      Asegun Henry wins National Science Foundation’s Alan T. Waterman Award

      by

      The National Science Foundation (NSF) today named Asegun Henry, an associate professor in MIT’s Department of Mechanical Engineering, as a 2023 recipient of its Alan T. Waterman Award. This award is the NSF’s highest honor for early-career researchers and provides funding for research in any science or engineering field. 

      This is the second year NSF has chosen to honor three researchers with the award. Henry is the sixth faculty member from MIT to receive this honor in its 47-year history, and is only the second mechanical engineer to ever win the award. In addition to a medal, Henry and his fellow awardees, Natalie S. King of Georgia State University and William Anderegg from the University of Utah, will each receive $1 million over five years for research in their chosen field of science.

      “I am thrilled to congratulate this year’s Waterman awardees, three outstanding scientists who are courageously tackling some of the most challenging societal problems through their ingenuity and innovative mindset,” says NSF Director Sethuraman Panchanathan. “Their pioneering accomplishments are precisely what the Waterman Award was created to recognize, and I look forward to their tremendous contributions in the future.”

      NSF recognizes Henry as an international thermal science and engineering leader. Henry has made breakthrough advances in nanoscale heat transfer and high-temperature energy systems. He directs the Atomistic Simulation and Energy (ASE) Research Group at MIT, focusing on heat transfer at the atomic level. He also works on developing technologies that can help mitigate climate change, addressing many problems from the atomic to the gigawatt scale.

      Henry and colleagues have led the development of several technological breakthroughs, setting a world record for the highest-temperature pump, using an all-ceramic mechanical pump to move liquid metal above 1,400 degrees Celsius, as well as the world record for thermophotovoltaic efficiency.

      “It has been challenging to push the field towards acceptance of new ideas, and it has been a path fraught with resistance and questioning of the validity of our results,” says Henry. “Receiving this award is vindicating and will impact my career greatly as it helps validate that the advances we’ve pioneered really do register as major contributions, and I pride myself on the impact of my work.”

      The Waterman Award will be presented to Henry at a ceremony held in Washington on May 9 during the National Science Board meeting.  More

      Robert Armstrong: A lifetime at the forefront of chemical engineering research and education

      by

      Robert C. Armstrong, the Chevron Professor of Chemical Engineering who has been the director of the MIT Energy Initiative (MITEI) since 2013 and part of MITEI’s leadership team since its inception in 2007, has announced that he will retire effective June 30. At that time he will have completed 50 years on the MIT faculty.  

      Armstrong plans to continue to work at 10 percent capacity, focusing on research projects on which he serves as principal investigator and also advising a number of graduate students.

      “Working at MIT has been a great honor and privilege for me,” says Armstrong. “Nowhere else can I imagine having had the opportunity to work with such exceptional students and colleagues and to have a ‘job’ that makes me want to get up every day to see what I can do to help humanity with its great challenges.”

      Armstrong joined the founding MITEI leadership team with Ernest Moniz, now the Cecil and Ida Green Professor of Physics and Engineering Systems emeritus and special advisor to the MIT president. When Moniz left MIT in 2013 to become U.S. secretary of energy, Armstrong was named MITEI director.

      “MITEI has enabled us to leverage MIT’s great talent base to make significant advances in energy research, education, and outreach,” says Armstrong. “This is an incredibly important and exciting time in energy, and there is much to be done in envisioning and implementing an energy transition that mitigates the worst impacts of climate change, provides energy justly and equitably to those around the world without access or with inadequate access, and improves security of energy supply. I have been honored to do this work with amazing colleagues at MITEI and throughout MIT, and I will be cheering that team on, as it races to reach net-zero greenhouse gas emissions by 2050.”

      MIT Vice President for Research Maria Zuber will form a search committee to select the new MITEI director. Zuber has worked closely with Armstrong since she became vice president for research in 2012.

      “Anyone who knows Bob knows that he is soft-spoken, but a person of deep conviction,” says Zuber. “He is a master of complexity, an admired educator, a respected leader, and a terrific colleague. During his decade as director, Bob has focused the MIT Energy Initiative on the urgent, daunting challenge of transforming the global energy system to respond to the climate crisis. In the last couple of years, Bob led the creation of MITEI’s Future Energy Systems Center, reflecting his keen understanding that an effective climate response requires integrated analysis and a systems approach — there is no one-fix-all solution. I congratulate Bob on a remarkable career, and I thank him for his half-century of dedicated service to MIT.”

      Armstrong joined the MIT faculty in 1973 after earning his doctorate in chemical engineering from the University of Wisconsin at Madison. A native of Louisiana, he earned his undergraduate degree in chemical engineering from Georgia Tech. He served as chair of the MIT Department of Chemical Engineering from 1996 until joining MITEI in 2007. 

      “In his 50 years at MIT, Bob has been a truly dedicated educator, researcher, and leader in our department, the Institute, and the field of chemical engineering,” says Paula T. Hammond, Institute professor and the head of the MIT Department of Chemical Engineering — a successor to Armstrong in that role. “During his time as head, he expertly expanded the breadth and depth of the department’s research and academics while maintaining its high level of excellence. He has served as a thoughtful and proactive mentor to so many of our faculty members, as well as a dedicated teacher and advocate for modernizing chemical engineering curriculum. We are extremely fortunate to have profited from his scholarship and leadership over the past several decades and will continue to benefit thanks to his vision and work toward the future of chemical engineering and energy.”

      In 2008, Armstrong was elected a member of the National Academy of Engineering, based on his research into non-Newtonian fluid mechanics, his leadership in chemical engineering education, and his co-authoring of influential chemical engineering textbooks. He became a fellow of the American Academy of Arts and Sciences in 2020.

      He received the 2006 Bingham Medal from The Society of Rheology, which is devoted to the study of the science of deformation and flow of matter, as well as the Founders Award (2020), the Warren K. Lewis Award (2006), and the Professional Progress Award (1992), all from the American Institute of Chemical Engineers. More

      Exploring the bow shock and beyond

      by

      For most people, the night sky conjures a sense of stillness, an occasional shooting star the only visible movement. A conversation with Rishabh Datta, however, unveils the supersonic drama crashing above planet Earth. The PhD candidate has focused his recent study on the plasma speeding through space, flung from sources like the sun’s corona and headed toward Earth, halted abruptly by colliding with the planet’s magnetosphere. The resulting shock wave is similar to the “bow shock” that forms around the nose cone of a supersonic jet, which manifests as the familiar sonic boom.

      The bow shock phenomenon has been well studied. “It’s probably one of the things that’s keeping life alive,” says Datta, “protecting us from the solar wind.” While he feels the magnetosphere provides “a very interesting space laboratory,” Datta’s main focus is, “Can we create this high-energy plasma that is moving supersonically in a laboratory, and can we study it? And can we learn things that are hard to diagnose in an astrophysical plasma?”

      Datta’s research journey to the bow shock and beyond began when he joined a research program for high school students at the National University Singapore. Tasked with culturing bacteria and measuring the amount of methane they produced in a biogas tank, Datta found his first research experience “quite nasty.”

      “I was working with chicken manure, and every day I would come home smelling completely awful,” he says.

      As an undergraduate at Georgia Tech, Datta’s interests turned toward solar power, compelled by a new technology he felt could generate sustainable energy. By the time he joined MIT’s Department of Mechanical Engineering, though, his interests had morphed into researching the heat and mass transfer from airborne droplets. After a year of study, he felt the need to go in a yet another direction.

      The subject of astrophysical plasmas had recently piqued his interest, and he followed his curiosity to Department of Nuclear Science and Engineering Professor Nuno Loureiro’s introductory plasma class. There he encountered Professor Jack Hare, who was sitting in on the class and looking for students to work with him.

      “And that’s how I ended up doing plasma physics and studying bow shocks,” he says, “a long and circuitous route that started with culturing bacteria.”

      Gathering measurements from MAGPIE

      Datta is interested in what he can learn about plasma from gathering measurements of a laboratory-created bow shock, seeking to verify theoretical models. He uses data already collected from experiments on a pulsed-power generator known as MAGPIE (the Mega-Ampere Generator of Plasma Implosion Experiments), located at Imperial College, London. By observing how long it takes a plasma to reach an obstacle, in this case a probe that measures magnetic fields, Datta was able to determine its velocity.   

      With the velocity established, an interferometry system was able to provide images of the probe and the plasma around it, allowing Datta to characterize the structure of the bow shock.

      “The shape depends on how fast sound waves can travel in a plasma,” says Datta. “And this ‘sound speed’ depends on the temperature.”

      The interdependency of these characteristics means that by imaging a shock it’s possible to determine temperature, sound speed, and other measurements more easily and cheaply than with other methods.

      “And knowing more about your plasma allows you to make predictions about, for example, electrical resistivity, which can be important for understanding other physics that might interest you,” says Datta, “like magnetic reconnection.”

      This phenomenon, which controls the evolution of such violent events as solar flares, coronal mass ejections, magnetic storms that drive auroras, and even disruptions in fusion tokamaks, has become the focus of his recent research. It happens when opposing magnetic fields in a plasma break and then reconnect, generating vast quantities of heat and accelerating the plasma to high velocities.

      Onward to Z

      Datta travels to Sandia National Laboratories in Albuquerque, New Mexico, to work on the largest pulsed power facility in the world, informally known as “the Z machine,” to research how the properties of magnetic reconnection change when a plasma emits strong radiation and cools rapidly.

      In future years, Datta will only have to travel across Albany Street on the MIT campus to work on yet another machine, PUFFIN, currently being built at the Plasma Science and Fusion Center (PSFC). Like MAGPIE and Z, PUFFIN is a pulsed power facility, but with the ability to drive the current 10 times longer than other machines, opening up new opportunities in high-energy-density laboratory astrophysics.

      Hare, who leads the PUFFIN team, is pleased with Datta’s increasing experience.

      “Working with Rishabh is a real pleasure,” he says, “He has quickly learned the ins and outs of experimental plasma physics, often analyzing data from machines he hasn’t even yet had the chance to see! While we build PUFFIN it’s really useful for us to carry out experiments at other pulsed-power facilities worldwide, and Rishabh has already written papers on results from MAGPIE, COBRA at Cornell in Ithaca, New York, and the Z Machine.”

      Pursuing climate action at MIT

      Hand-in-hand with Datta’s quest to understand plasma is his pursuit of sustainability, including carbon-free energy solutions. A member of the Graduate Student Council’s Sustainability Committee since he arrived in 2019, he was heartened when MIT, revising their climate action plan, provided him and other students the chance to be involved in decision-making. He led focus groups to provide graduate student input on the plan, raising issues surrounding campus decarbonization, the need to expand hiring of early-career researchers working on climate and sustainability, and waste reduction and management for MIT laboratories.

      When not focused on bringing astrophysics to the laboratory, Datta sometimes experiments in a lab closer to home — the kitchen — where he often challenges himself to duplicate a recipe he has recently tried at a favorite restaurant. His stated ambition could apply to his sustainability work as well as to his pursuit of understanding plasma.

      “The goal is to try and make it better,” he says. “I try my best to get there.”

      Datta’s work has been funded, in part, by the National Science Foundation, National Nuclear Security Administration, and the Department of Energy. More

      Exploring new sides of climate and sustainability research

      by

      When the MIT Climate and Sustainability Consortium (MCSC) launched its Climate and Sustainability Scholars Program in fall 2022, the goal was to offer undergraduate students a unique way to develop and implement research projects with the strong support of each other and MIT faculty. Now into its second semester, the program is underscoring the value of fostering this kind of network — a community with MIT students at its core, exploring their diverse interests and passions in the climate and sustainability realms.Inspired by MIT’s successful SuperUROP [Undergraduate Research Opportunities Program], the yearlong MCSC Climate and Sustainability Scholars Program includes a classroom component combined with experiential learning opportunities and mentorship, all centered on climate and sustainability topics.“Harnessing the innovation, passion, and expertise of our talented students is critical to MIT’s mission of tackling the climate crisis,” says Anantha P. Chandrakasan, dean of the School of Engineering, Vannevar Bush Professor of Electrical Engineering and Computer Science, and chair of the MCSC. “The program is helping train students from a variety of disciplines and backgrounds to be effective leaders in climate and sustainability-focused roles in the future.”

      “What we found inspiring about MIT’s existing SuperUROP program was how it provides students with the guidance, training, and resources they need to investigate the world’s toughest problems,” says Elsa Olivetti, the Esther and Harold E. Edgerton Associate Professor in Materials Science and Engineering and MCSC co-director. “This incredible level of support and mentorship encourages students to think and explore in creative ways, make new connections, and develop strategies and solutions that propel their work forward.”The first and current cohort of Climate and Sustainability Scholars consists of 19 students, representing MIT’s School of Engineering, MIT Schwarzman College of Computing, School of Science, School of Architecture and Planning, and MIT Sloan School of Management. These students are learning new perspectives, approaches, and angles in climate and sustainability — from each other, MIT faculty, and industry professionals.Projects with real-world applicationsStudents in the program work directly with faculty and principal investigators across MIT to develop their research projects focused on a large scope of sustainability topics.

      “This broad scope is important,” says Desirée Plata, MIT’s Gilbert W. Winslow Career Development Professor in Civil and Environmental Engineering, “because climate and sustainability solutions are needed in every facet of society. For a long time, people were searching for a ‘silver bullet’ solution to the climate change problems, but we didn’t get to this point with a single technological decision. This problem was created across a spectrum of sociotechnological activities, and fundamentally different thinking across a spectrum of solutions is what’s needed to move us forward. MCSC students are working to provide those solutions.”

      Undergraduate student and physics major M. (MG) Geogdzhayeva is working with Raffaele Ferrari, Cecil and Ida Green Professor of Oceanography in the Department of Earth, Atmospheric and Planetary Sciences, and director of the Program in Atmospheres, Oceans, and Climate, on their project “Using Continuous Time Markov Chains to Project Extreme Events under Climate.” Geogdzhayeva’s research supports the Flagship Climate Grand Challenges project that Ferrari is leading along with Professor Noelle Eckley Selin.

      “The project I am working on has a similar approach to the Climate Grand Challenges project entitled “Bringing computation to the climate challenge,” says Geogdzhayeva. “I am designing an emulator for climate extremes. Our goal is to boil down climate information to what is necessary and to create a framework that can deliver specific information — in order to develop valuable forecasts. As someone who comes from a physics background, the Climate and Sustainability Scholars Program has helped me think about how my research fits into the real world, and how it could be implemented.”

      Investigating technology and stakeholders

      Within technology development, Jade Chongsathapornpong, also a physics major, is diving into photo-modulated catalytic reactions for clean energy applications. Chongsathapornpong, who has worked with the MCSC on carbon capture and sequestration through the Undergraduate Research Opportunities Program (UROP), is now working with Harry Tuller, MIT’s R.P. Simmons Professor of Ceramics and Electronic Materials. Louise Anderfaas, majoring in materials science and engineering, is also working with Tuller on her project “Robust and High Sensitivity Detectors for Exploration of Deep Geothermal Wells.”Two other students who have worked with the MCSC through UROP include Paul Irvine, electrical engineering and computer science major, who is now researching American conservatism’s current relation to and views about sustainability and climate change, and Pamela Duke, management major, now investigating the use of simulation tools to empower industrial decision-makers around climate change action.Other projects focusing on technology development include the experimental characterization of poly(arylene ethers) for energy-efficient propane/propylene separations by Duha Syar, who is a chemical engineering major and working with Zachary Smith, the Robert N. Noyce Career Development Professor of Chemical Engineering; developing methods to improve sheet steel recycling by Rebecca Lizarde, who is majoring in materials science and engineering; and ion conduction in polymer-ceramic composite electrolytes by Melissa Stok, also majoring in materials science and engineering.

      “My project is very closely connected to developing better Li-Ion batteries, which are extremely important in our transition towards clean energy,” explains Stok, who is working with Bilge Yildiz, MIT’s Breene M. Kerr (1951) Professor of Nuclear Science and Engineering. “Currently, electric cars are limited in their range by their battery capacity, so working to create more effective batteries with higher energy densities and better power capacities will help make these cars go farther and faster. In addition, using safer materials that do not have as high of an environmental toll for extraction is also important.” Claire Kim, a chemical engineering major, is focusing on batteries as well, but is honing in on large form factor batteries more relevant for grid-scale energy storage with Fikile Brushett, associate professor of chemical engineering.Some students in the program chose to focus on stakeholders, which, when it comes to climate and sustainability, can range from entities in business and industry to farmers to Indigenous people and their communities. Shivani Konduru, an electrical engineering and computer science major, is exploring the “backfire effects” in climate change communication, focusing on perceptions of climate change and how the messenger may change outcomes, and Einat Gavish, mathematics major, on how different stakeholders perceive information on driving behavior.Two students are researching the impact of technology on local populations. Anushree Chaudhuri, who is majoring in urban studies and planning, is working with Lawrence Susskind, Ford Professor of Urban and Environmental Planning, on community acceptance of renewable energy siting, and Amelia Dogan, also an urban studies and planning major, is working with Danielle Wood, assistant professor of aeronautics and astronautics and media arts and sciences, on Indigenous data sovereignty in environmental contexts.

      “I am interviewing Indigenous environmental activists for my project,” says Dogan. “This course is the first one directly related to sustainability that I have taken, and I am really enjoying it. It has opened me up to other aspects of climate beyond just the humanity side, which is my focus. I did MIT’s SuperUROP program and loved it, so was excited to do this similar opportunity with the climate and sustainability focus.”

      Other projects include in-field monitoring of water quality by Dahlia Dry, a physics major; understanding carbon release and accrual in coastal wetlands by Trinity Stallins, an urban studies and planning major; and investigating enzyme synthesis for bioremediation by Delight Nweneka, an electrical engineering and computer science major, each linked to the MCSC’s impact pathway work in nature-based solutions.

      The wide range of research topics underscores the Climate and Sustainability Program’s goal of bringing together diverse interests, backgrounds, and areas of study even within the same major. For example, Helena McDonald is studying pollution impacts of rocket launches, while Aviva Intveld is analyzing the paleoclimate and paleoenvironment background of the first peopling of the Americas. Both students are Earth, atmospheric and planetary sciences majors but are researching climate impacts from very different perspectives. Intveld was recently named a 2023 Gates Cambridge Scholar.

      “There are students represented from several majors in the program, and some people are working on more technical projects, while others are interpersonal. Both approaches are really necessary in the pursuit of climate resilience,” says Grace Harrington, who is majoring in civil and environmental engineering and whose project investigates ways to optimize the power of the wind farm. “I think it’s one of the few classes I’ve taken with such an interdisciplinary nature.”

      Perspectives and guidance from MIT and industry expertsAs students are developing these projects, they are also taking the program’s course (Climate.UAR), which covers key topics in climate change science, decarbonization strategies, policy, environmental justice, and quantitative methods for evaluating social and environmental impacts. The course is cross-listed in departments across all five schools and is taught by an experienced and interdisciplinary team. Desirée Plata was central to developing the Climate and Sustainability Scholars Programs and course with Associate Professor Elsa Olivetti, who taught the first semester. Olivetti is now co-teaching the second semester with Jeffrey C. Grossman, the Morton and Claire Goulder and Family Professor in Environmental Systems, head of the Department of Materials Science and Engineering, and MCSC co-director. The course’s writing instructors are Caroline Beimford and David Larson.  

      “I have been introduced to a lot of new angles in the climate space through the weekly guest lecturers, who each shared a different sustainability-related perspective,” says Claire Kim. “As a chemical engineering major, I have mostly looked into the technologies for decarbonization, and how to scale them, so learning about policy, for example, was helpful for me. Professor Black from the Department of History spoke about how we can analyze the effectiveness of past policy to guide future policy, while Professor Selin talked about framing different climate policies as having co-benefits. These perspectives are really useful because no matter how good a technology is, you need to convince other people to adopt it, or have strong policy in place to encourage its use, in order for it to be effective.”

      Bringing the industry perspective, guests have presented from MCSC member companies such as PepsiCo, Holcim, Apple, Cargill, and Boeing. As an example, in one class, climate leaders from three companies presented together on their approaches to setting climate goals, barriers to reaching them, and ways to work together. “When I presented to the class, alongside my counterparts at Apple and Boeing, the student questions pushed us to explain how can collaborate on ways to achieve our climate goals, reflecting the broader opportunity we find within the MCSC,” says Dana Boyer, sustainability manager at Cargill.

      Witnessing the cross-industry dynamics unfold in class was particularly engaging for the students. “The most beneficial part of the program for me is the number of guest lectures who have come in to the class, not only from MIT but also from the industry side,” Grace Harrington adds. “The diverse range of people talking about their own fields has allowed me to make connections between all my classes.”Bringing in perspectives from both academia and industry is a reflection of the MCSC’s larger mission of linking its corporate members with each other and with the MIT community to develop scalable climate solutions.“In addition to focusing on an independent research project and engaging with a peer community, we’ve had the opportunity to hear from speakers across the sustainability space who are also part of or closely connected to the MIT ecosystem,” says Anushree Chaudhuri. “These opportunities have helped me make connections and learn about initiatives at the Institute that are closely related to existing or planned student sustainability projects. These connections — across topics like waste management, survey best practices, and climate communications — have strengthened student projects and opened pathways for future collaborations.

      Having a positive impact as students and after graduation

      At the start of the program, students identified several goals, including developing focused independent research questions, drawing connections and links with real-world challenges, strengthening their critical thinking skills, and reflecting on their future career ambitions. A common thread throughout them all: the commitment to having a meaningful impact on climate and sustainability challenges both as students now, and as working professionals after graduation.“I’ve absolutely loved connecting with like-minded peers through the program. I happened to know most of the students coming in from various other communities on campus, so it’s been a really special experience for all of these people who I couldn’t connect with as a cohesive cohort before to come together. Whenever we have small group discussions in class, I’m always grateful for the time to learn about the interdisciplinary research projects everyone is involved with,” concludes Chaudhuri. “I’m looking forward to staying in touch with this group going forward, since I think most of us are planning on grad school and/or careers related to climate and sustainability.”

      The MCSC Climate and Sustainability Scholars Program is representative of MIT’s ambitious and bold initiatives on climate and sustainability — bringing together faculty and students across MIT to collaborate with industry on developing climate and sustainability solutions in the context of undergraduate education and research.

      Volunteer committee helps the MIT community live and work sustainably

      by

      April 22 marks the arrival of Earth Day, which provides all of us with a good reason to think of ways to live more sustainably. For more than 20 years, the MIT Working Green Committee has helped community members do just that by encouraging the reuse and recycling of possessions.

      Made up entirely of volunteers, the committee has played an important role in promoting more sustainable operations at MIT and raising awareness of the importance of conservation.

      “We try to provide a place for people to learn how to live and work in a more environmentally friendly way,” says committee co-chair Rebecca Fowler, a senior administrative assistant in MIT’s Office of Sustainability.

      The committee hosts regular Choose to Reuse events to give MIT’s community members a chance to donate unwanted items — or find free things that just might become prized possessions. It also provides resources to help host more sustainable events, make more sustainable purchasing decisions, and learn more about recycling.

      “The recycling industry is very frustrating, so people are always asking what to do,” Fowler says. “They feel like they make the wrong decisions and just want to know how to do it. We get a lot of questions, and we’re always there to help find answers.”

      Committee members say they’ve realized devoting a little time each month to things like recycling education, and hosting events can make a big difference in reducing waste. In last month’s Choose to Reuse event, more than 100 people dropped off thousands of items including clothing, housewares, and office supplies. MIT’s always-active Reuse email lists, which the committee encourages community members to join, are another great way to pass gently used items to others who can give them new life.

      “The goal is to keep things out of landfills, and the Choose to Reuse event shows you immediate results,” says committee co-chair Gianna Hernandez-Figueroa, who is the assistant to the director at the MIT AgeLab. “It’s inspiring because people are excited to put things in the hands of someone who is going to repurpose it. It’s a circular event that’s really beautiful.”

      Choose to Reuse events are typically on the third Thursday of every other month, although the next one — the last for the spring semester — is on Monday, April 24.

      The committee is one of the only groups on campus run by support staff, whose responsibilities involve clerical duties, data processing, and library and accounting functions, among other things. It is a subcommittee of the Working Group for Support Staff.

      The committee began as the Working Group on Recycling in 2000 at a time when MIT’s recycling rate was around 11 percent. By 2006, MIT had reached a 40 percent recycling rate and received a Go Green Award from the City of Cambridge. That year the committee earned an MIT Excellence Awards for its work.

      Around 2011, the group started hosting Choose to Reuse events, which became an instant success.

      “I really believe in the gift economy, specifically in academic settings where you have a lot of international students,” Hernandez-Figueroa says. “Plus, Boston is an expensive city!”

      For a long time, the group was run by Ruth Davis, who served as MIT’s manager for recycling and materials management and retired last year. Since Davis left, others have stepped up.

      “A lot of the volunteers have been around since the first Choose to Reuse event 13 years ago,” Fowler says, adding that the committee is always looking for more volunteers. “They’re all very committed to the event and to the cause.”

      The organization is also a way for support staff to gain new skills. Fowler credits her experience working on the committee with improving her project management and website design abilities.

      “We really emphasize capacity building,” Fowler says. “If there’s a skill a volunteer would like to develop, we can explore ways to do that through the committee. That’s something I’d like to continue: finding people’s strengths and helping them build their careers.”

      Overall, Fowler says the committee aligns with MIT’s commitment to make an impact.

      The group’s long history “shows a commitment to environmentalism and sustainability and a yearning to do more beyond what is in your job responsibilities,” she says. “It really shows the commitment to volunteerism of MIT’s staff members.” More

      3 Questions: New MIT major and its role in fighting climate change

      by

      Launched this month, MIT’s new Bachelor of Science in climate system science and engineering is jointly offered by the departments of Civil and Environmental Engineering (CEE) and Earth, Atmospheric and Planetary Sciences (EAPS). As part of MIT’s commitment to aid the global response to climate change, the new degree program is designed to train the next generation of leaders, providing a foundational understanding of both the Earth system and engineering principles — as well as an understanding of human and institutional behavior as it relates to the climate challenge. Jadbabaie and Van der Hilst discuss the new Course 1-12 multidisciplinary major and why it’s needed now at MIT. 

      Q: What was the idea behind launching this new major at MIT?

      Jadbabaie: Climate change is an incredibly important issue that we must address, and time is of the essence. MIT is in a unique position to play a leadership role in this effort. We not only have the ability to advance the science of climate change and deepen our understanding of the climate system, but also to develop innovative engineering solutions for sustainability that can help us meet the climate goals set forth in the Paris Agreement. It is important that our educational approach also incorporates other aspects of this cross-cutting issue, ranging from climate justice, policy, to economics, and MIT is the perfect place to make this happen. With Course 1’s focus on sustainability across scales, from the nano to the global scale, and with Course 12 studying Earth system science in general, it was a natural fit for CEE and EAPS to tackle this challenge together. It is my belief that we can leverage our collective expertise and resources to make meaningful progress. There has never been a more crucial time for us to advance students’ understanding of both climate science and engineering, as well as their understanding of the societal implications of climate risk.

      Van der Hilst: Climate change is a global issue, and the solutions we urgently need for building a net-zero future must consider how everything is connected. The Earth’s climate is a complex web of cause and effect between the oceans, atmosphere, ecosystems, and processes that shape the surface and environmental systems of the planet. To truly understand climate risks, we need to understand the fundamental science that governs these interconnected systems — and we need to consider the ways that human activity influences their behavior. The types of large-scale engineering projects that we need to secure a sustainable future must take into consideration the Earth system itself. A systems approach to modeling is crucial if we are to succeed at inventing, designing, and implementing solutions that can reduce greenhouse gas emissions, build climate resilience, and mitigate the inevitable climate-related natural disasters that we’ll face. That’s why our two departments are collaborating on a degree program that equips students with foundational climate science knowledge alongside fundamental engineering principles in order to catalyze the innovation we’ll need to meet the world’s 2050 goals.

      Q: How is MIT uniquely positioned to lead undergraduate education in climate system science and engineering? 

      Jadbabaie: It’s a great example of how MIT is taking a leadership role and multidisciplinary approach to tackling climate change by combining engineering and climate system science in one undergraduate major. The program leverages MIT’s academic strengths, focusing on teaching hard analytical and computational skills while also providing a curriculum that includes courses in a wide range of topics, from climate economics and policy to ethics, climate justice, and even climate literature, to help students develop an understanding of the political and social issues that are tied to climate change. Given the strong ties between courses 1 and 12, we want the students in the program to be full members of both departments, as well as both the School of Engineering and the School of Science. And, being MIT, there is no shortage of opportunities for undergraduate research and entrepreneurship — in fact, we specifically encourage students to participate in the active research of the departments. The knowledge and skills our students gain will enable them to serve the nation and the world in a meaningful way as they tackle complex global-scale environmental problems. The students at MIT are among the most passionate and driven people out there. I’m really excited to see what kind of innovations and solutions will come out of this program in the years to come. I think this undergraduate major is a fantastic step in the right direction.

      Q: What opportunities will the major provide to students for addressing climate change?

      Van der Hilst: Both industry and government are actively seeking new talent to respond to the challenges — and opportunities — posed by climate change and our need to build a sustainable future. What’s exciting is that many of the best jobs in this field call for leaders who can combine the analytical skill of a scientist with the problem-solving mindset of an engineer. That’s exactly what this new degree program at MIT aims to prepare students for — in an expanding set of careers in areas like renewable energy, civil infrastructure, risk analysis, corporate sustainability, environmental advocacy, and policymaking. But it’s not just about career opportunities. It’s also about making a real difference and safeguarding our future. It’s not too late to prevent much more damaging changes to Earth’s climate. Indeed, whether in government, industry, or academia, MIT students are future leaders — as such it is critically important that all MIT students understand the basics of climate system science and engineering along with math, physics, chemistry, and biology. The new Course 1-12 degree was designed to forge students who are passionate about protecting our planet into the next generation of leaders who can fast-track high-impact, science-based solutions to aid the global response, with an eye toward addressing some of the uneven social impacts inherent in the climate crisis.

      Moving perovskite advancements from the lab to the manufacturing floor

      by

      The following was issued as a joint announcement from MIT.nano and the MIT Research Laboratory for Electronics; CubicPV; Verde Technologies; Princeton University; and the University of California at San Diego.

      Tandem solar cells are made of stacked materials — such as silicon paired with perovskites — that together absorb more of the solar spectrum than single materials, resulting in a dramatic increase in efficiency. Their potential to generate significantly more power than conventional cells could make a meaningful difference in the race to combat climate change and the transition to a clean-energy future.

      However, current methods to create stable and efficient perovskite layers require time-consuming, painstaking rounds of design iteration and testing, inhibiting their development for commercial use. Today, the U.S. Department of Energy Solar Energy Technologies Office (SETO) announced that MIT has been selected to receive an $11.25 million cost-shared award to establish a new research center to address this challenge by using a co-optimization framework guided by machine learning and automation.

      A collaborative effort with lead industry participant CubicPV, solar startup Verde Technologies, and academic partners Princeton University and the University of California San Diego (UC San Diego), the center will bring together teams of researchers to support the creation of perovskite-silicon tandem solar modules that are co-designed for both stability and performance, with goals to significantly accelerate R&D and the transfer of these achievements into commercial environments.

      “Urgent challenges demand rapid action. This center will accelerate the development of tandem solar modules by bringing academia and industry into closer partnership,” says MIT professor of mechanical engineering Tonio Buonassisi, who will direct the center. “We’re grateful to the Department of Energy for supporting this powerful new model and excited to get to work.”

      Adam Lorenz, CTO of solar energy technology company CubicPV, stresses the importance of thinking about scale, alongside quality and efficiency, to accelerate the perovskite effort into the commercial environment. “Instead of chasing record efficiencies with tiny pixel-sized devices and later attempting to stabilize them, we will simultaneously target stability, reproducibility, and efficiency,” he says. “It’s a module-centric approach that creates a direct channel for R&D advancements into industry.”

      The center will be named Accelerated Co-Design of Durable, Reproducible, and Efficient Perovskite Tandems, or ADDEPT. The grant will be administered through the MIT Research Laboratory for Electronics (RLE).

      David Fenning, associate professor of nanoengineering at UC San Diego, has worked with Buonassisi on the idea of merging materials, automation, and computation, specifically in this field of artificial intelligence and solar, since 2014. Now, a central thrust of the ADDEPT project will be to deploy machine learning and robotic screening to optimize processing of perovskite-based solar materials for efficiency and durability.

      “We have already seen early indications of successful technology transfer between our UC San Diego robot PASCAL and industry,” says Fenning. “With this new center, we will bring research labs and the emerging perovskite industry together to improve reproducibility and reduce time to market.”

      “Our generation has an obligation to work collaboratively in the fight against climate change,” says Skylar Bagdon, CEO of Verde Technologies, which received the American-Made Perovskite Startup Prize. “Throughout the course of this center, Verde will do everything in our power to help this brilliant team transition lab-scale breakthroughs into the world where they can have an impact.”

      Several of the academic partners echoed the importance of the joint effort between academia and industry. Barry Rand, professor of electrical and computer engineering at the Andlinger Center for Energy and the Environment at Princeton University, pointed to the intersection of scientific knowledge and market awareness. “Understanding how chemistry affects films and interfaces will empower us to co-design for stability and performance,” he says. “The center will accelerate this use-inspired science, with close guidance from our end customers, the industry partners.”

      A critical resource for the center will be MIT.nano, a 200,000-square-foot research facility set in the heart of the campus. MIT.nano Director Vladimir Bulović, the Fariborz Maseeh (1990) Professor of Emerging Technology, says he envisions MIT.nano as a hub for industry and academic partners, facilitating technology development and transfer through shared lab space, open-access equipment, and streamlined intellectual property frameworks.

      “MIT has a history of groundbreaking innovation using perovskite materials for solar applications,” says Bulović. “We’re thrilled to help build on that history by anchoring ADDEPT at MIT.nano and working to help the nation advance the future of these promising materials.”

      MIT was selected as a part of the SETO Fiscal Year 2022 Photovoltaics (PV) funding program, an effort to reduce costs and supply chain vulnerabilities, further develop durable and recyclable solar technologies, and advance perovskite PV technologies toward commercialization. ADDEPT is one project that will tackle perovskite durability, which will extend module life. The overarching goal of these projects is to lower the levelized cost of electricity generated by PV.

      Research groups involved with the ADDEPT project at MIT include Buonassisi’s Accelerated Materials Laboratory for Sustainability (AMLS), Bulović’s Organic and Nanostructured Electronics (ONE) Lab, and the Bawendi Group led by Lester Wolfe Professor in Chemistry Moungi Bawendi. Also working on the project is Jeremiah Mwaura, research scientist in the ONE Lab. More

      Podcast: Curiosity Unbounded, Episode 1 — How a free-range kid from Maine is helping green-up industrial practices

      by

      The Curiosity Unbounded podcast is a conversation between MIT President Sally Kornbluth and newly-tenured faculty members. President Kornbluth invites us to listen in as she dives into the research happening in MIT’s labs and in the field. Along the way, she and her guests discuss pressing issues, as well as what inspires the people running at the world’s toughest challenges at one of the most innovative institutions on the planet.

      In this episode, President Kornbluth sits down with Desirée Plata, a newly tenured associate professor of civil and environmental engineering. Her work focuses on making industrial processes more environmentally friendly, and removing methane — a key factor in global warming — from the air.

      FULL TRANSCRIPT:

      Sally Kornbluth: Hello, I’m Sally Kornbluth, president of MIT, and I’m thrilled to welcome you to this MIT community podcast, Curiosity Unbounded. In my first few months at MIT, I’ve been particularly inspired by talking with members of our faculty who recently earned tenure. Like their colleagues, they are pushing the boundaries of knowledge. Their passion and brilliance, their boundless curiosity, offer a wonderful glimpse of the future of MIT.

      Today, I’m talking with Desirée Plata, associate professor of civil and environmental engineering. Desirée’s work is focused on predicting the environmental impact of  industrial processes and translating that research to real-world technologies. She describes herself as an environmental chemist. Tell me a little more about that. What led you to this work either personally or professionally?

      Desirée Plata: I guess I always loved chemistry, but before that, I was just a kid growing up in the state of Maine. I like to describe myself as a free-range kid. I ran around and talked to the neighbors and popped into the local businesses. One thing I observed in my grandparents’ town was that there were a whole lot of sick people. Not everybody, but maybe every other house. I remember being about seven or eight years old and driving home with my mom to our apartment one day and saying, “It’s got to be something everybody shares. The water, maybe something in the food or the air.” That was really my first environmental hypothesis.

      Sally: You had curiosity unbounded even when you were a child. 

      Desirée: That’s right. I spent the next several decades trying to figure it out and ultimately discovered that there was something in the water where my grandmother lived. In that time, I had earned a chemistry degree and came to MIT to do my grad work at MIT in the Woods Hole Oceanographic in environmental chemistry and chemical oceanography.

      Sally: You saw a pattern, you thought about it, and it took some time to get the tools to actually address the questions, but eventually you were there. That is great. As I understand it, you have two distinct areas of interest. One is getting methane out of the atmosphere to mitigate climate warming, and the other is making industrial processes more environmentally sound. Do you see these two as naturally connected?

      Desirée: I’ll start by saying that when I was young and thinking about this chemical contamination that I hypothesized was there in my grandmother’s neighborhood, one of the things—when I finally found out there was a Superfund site there—one of the things I discovered was that it was owned by close family friends. They were our neighbors. The decisions that they made as part of their industrial practice were just part of standard operating procedure. That’s when it clicked for me that industry is just going along, hoping to innovate to make the world a better place. When these environmental impacts occur, it’s often because they didn’t have enough information or know the right questions to ask. I was in graduate school at the time and said, “I’m at one of the most innovative places on planet Earth. I want to go knock on the doors of other labs and say, ‘What are you making and how can I help you make it better?'”

      If we all flash back to around 2008 or so, hydraulic fracturing was really taking off in this country and there was a lot of hypotheses about the number of chemicals being used in that process. It turns out that there are many hundreds of chemicals being used in the hydraulic fracturing process. My group has done an immense amount of work to study every groundwater we could get our hands on across the Appalachian region of the eastern United States, which is where a lot of this development took place and is still taking place. One of the things we discovered was that some of the biggest environmental impacts are actually not from the injected chemicals but from the released methane that’s coming into the atmosphere. Methane is growing at an exorbitant rate and is responsible for about as much warming as CO2 over the next 10 years. I started realizing that we, as engineers and scientists, would need a way to get these emissions back. To take them back from the atmosphere, if you will. To abate methane at very dilute concentrations. That’s what led to my work in methane abatement and methane mitigation.

      Sally: Interesting. Am I wrong about when we think about the impact of agriculture on the environment, that methane is a big piece of that as well?

      Desirée: You are certainly not wrong there. If you look at anthropogenic emissions or human-derived emissions, more than half are associated with agricultural practices. The cultivation of meat and dairy in particular. Cows and sheep are what are known as enteric methane formers. Part of their digestion process actually leads to the formation of methane. It’s estimated that about 28% of the global methane cycle is associated with enteric methane formers in our agricultural practices as humans. There’s another 18% that’s associated with fossil energy extraction.

      Sally: That’s really interesting. Thinking about your work then, particularly in agriculture, part of the equation has got to be how people live, what they eat, and production of methane as part of the sustainability of agriculture. The other part then seems to be how you actually, if you will, mitigate what we’ve already bought in terms of methane in the environment.

      Desirée: Yes, this is a really important topic right now.

      Sally: Tell me a little bit about, maybe in semi-lay terms, about how you think about removal of methane from the environment.

      Desirée: Recently, over 120 countries signed something called the Global Methane Pledge, which is essentially a pledge to reduce 45% of methane emissions by 2030. If you can do that, you can save about 0.5 degree centigrade warming by 2100. That’s a full third of the 1.5 degrees that politicians speak about. We can argue about whether or not that’s really the full extent of the warming we’ll see, but the point is that methane impacts near-term warming in our lifetimes. It’s one of the unique greenhouse gases that can do that.

      It’s called a short-lived climate pollutant. What that means is that it lives in the atmosphere for about 12 years before it’s removed. That means if you take it out of the atmosphere, you’re going to have a rapid reduction in the total warming of planet Earth, the total radiative forcing. Your question more specifically was about, how do we grapple with this? We’ve already omitted so much methane. How do we think about, as technologists, getting it back? It’s a really hard problem, actually. In the air in the room in front of us that we’re breathing, only two of the million molecules in front of us are methane. 417 or so are CO2. If you think direct air capture of CO2 is hard, direct air capture of methane is that much harder.

      The other thing that makes methane a challenge to abate is that activating the bonds in methane to promote its destruction or its removal is really, really tricky. It’s one of the smallest carbon-based molecules. It doesn’t have what we call “Van der Waals interactions”—there are no handles to grab onto. It’s not polar. That first destruction and that first C-H bond is what we as chemists would call “spin forbidden”. It’s hard to do and it takes a lot of energy to do that. One of the things we’ve developed in my lab is a catalyst that’s based on earth-abundant materials. There are some other groups at MIT that also work on these same types of materials. It’s able to convert methane at very low levels, down to the levels that we’re breathing in this room right now.

      Sally: That’s fascinating. do you see that as being something that will move to practical application?

      Desirée: One of the things that we’re doing to try to translate this to meaningful applications for the world is to scale the technology. We’re fortunate to have funding from several different sources, some private philanthropy groups and the United States Department of Energy. They’re helping us over the next three years try to scale this in places where it might matter most. Perhaps counterintuitive places, coal mines. Coal mines emit a lot of methane and it happens to be enriched in such a way that it releases energy. It might release enough energy to actually pay for the technology itself. Another place we’re really focused on is dairy.

      Sally: Really interesting. You mentioned at the beginning that you were at MIT, you left, you came back. I’m just wondering — I’m new to MIT and, obviously, I’m just learning it — but how do you think about the MIT community or culture in a way that is particularly helpful in advancing your work?

      Desirée: For me, I was really excited to come back to MIT because it is such an innovative place. If you’re someone who says, “I want to change the way we invent materials and processes,” it’s one of the best places you could possibly be. Because you can walk down the hall and bump into people who are making new things, new molecules, new materials, and say, “How can we incorporate the environment into our decision-making process?”

      As engineering professors, we’re guilty of teaching our students to optimize for performance and cost. They go out into their jobs, and guess what? That’s what they optimize for. We want to transition, and we’re at a point in our understanding of the earth system, that we could actually start to incorporate environmental objectives into that design process.

      Engineering professors of tomorrow should, say, optimize for performance and cost and the environment. That’s really what made me very excited to come back to MIT. Not just the great research that’s going on in every nook and corner of the Institute, but also thinking about how we might influence engineering education so that this becomes part of the fabric of how humans invent new practices and processes.

      Sally: If you look back in your past, you talked about your childhood in Maine and observing these patterns. You talked about your training and how you came to MIT and have really been, I think, thriving here. Was there a path not taken, a road not taken if you hadn’t become an environmental chemist? Was there something else you really wanted to do?

      Desirée: That’s such a great question. I have a lot of loves. I love the ocean. I love writing. I love teaching and I’m doing that, so I’m lucky there. I also love the beer business. My family’s in the beer business in Maine. I thought, as a biochemist, I would always be able to fall back on that if I needed to. My family’s not in the beer business because we’re particularly good at making beer, but because they’re interested in making businesses and creating opportunities for people. That’s been an important part of our role in the state of Maine.

      MIT really supports that side of my mind, as well. I love the entrepreneurial ecosystem that exists here. I love that when you bump into people and you have a crazy idea, instead of giving you all the reasons it won’t work, an MIT person gives you all the reasons it won’t work and then they say, “This is how we’re going to make it happen.” That’s really fun and exciting. The entrepreneurship environment that exists here is really very supportive of the translation process that has to happen to get something from the lab to the global impact that we’re looking for. That supports my mission just so much. It’s been a joy.

      Sally: That’s excellent. You weren’t actually tempted to become a yeast cell biologist in the service of beer production?

      Desirée: No, no, but I joke, “They only call me when something goes really bad.”

      Sally: That’s really funny. You experienced MIT as a student, now you’re experiencing it as a faculty member. What do you wish there was one thing about each group that the other knew?

      Desirée: I wish that, speaking with my faculty hat on, that the students knew just how much we care about them. I know that some of them do and really appreciate that. When I send an email at 3:00 in the morning, I get emails back from my colleagues at 3:00 in the morning. We work around the clock and we don’t do that for ourselves. We do that to make great sustainable systems for them and to create opportunity for them to propel themselves forward. To me, that’s one of the common unifying features of an MIT faculty member. We care really deeply about the student experience.

      As a student, I think that we’re hungry to learn. We wanted to really see the ins and outs of operation, how to run a research lab. I think sometimes faculty try to spare their students from that and maybe it’s okay to let them know just what’s going on in all those meetings that we sit through.

      Sally: That’s interesting. I think there are definitely things you find out when you become a faculty member and you’re like, “Oh, so this is what they were thinking.” With regard to the passion of the faculty about teaching, it really is remarkable here. I really think some of the strongest researchers here are so invested in teaching and you see that throughout the community.

      Desirée: It’s a labor of love for sure.

      Sally: Exactly. You talked a little bit about the passion for teaching. Were there teachers along your way that you really think impacted you and changed the direction of what you’re doing?

      Desirée: Yes, absolutely. I could name all of them. I had a kindergarten teacher who would stay after school and wait for my mom to be done work. I was raised by a single mom and her siblings and that was amazing. I had a fourth-grade teacher who helped promote me through school and taught me to love the environment. If you ask fourth graders if they saw any trash on the way to school, they’ll all say, “No.” You take them outside and give them a trash bag to fill up and it’ll be full by the end of the hour. This is something I’ve done with students in Cambridge to this day and this was many years on now. She really got me aware and thinking about environmental problems and how we might change systems.

      Sally: I think it’s really great for faculty to think about their own experiences, but also to hear people who become faculty members reflect on the great impact their own teachers had. I think the things folks are doing here are going to reverberate in their student’s minds for many, many years. It also is interesting in terms of thinking about the pipeline and when you get students interested in science. You talk about your own early years of education that really ultimately had an impact.

      It’s funny, when I became president at MIT, I got a note from my second-grade teacher. I remembered her like it was yesterday. These are people that really had an impact. It’s great that we honor teaching here at MIT and we acknowledge that this is going to have a really big impact on our student’s lives.

      Desirée: Yes, absolutely. It’s a privilege to teach these top talents. At many schools around the country, it’s just young people that have so much potential. I feel like when we walk into that classroom, we’ve got to bring inspiration with us along with the tangible, practical skills. It’s been great to see what they become.

      Sally: Tell me a little bit about what you do outside of work. When you ask faculty hobbies, sometimes I go, “Hobbies?” There must be something you spend your time on. I’m just curious.

      Desirée: We’re worried we’re going to fail this part of the Q&A. Yes. I have four children.

      Sally: You don’t need any hobbies then.

      Desirée: I know. It’s been the good graces of the academic institution. Just for those people who are out there thinking about going into academia and say, “It’s too hard. I couldn’t possibly have the work and life that I seek if I go into academia,” I don’t think that’s true anymore. I know there are a lot of women who paved the way for me, and men for that matter. I remember my PhD advisors being fully present for their children. I’ve been very fortunate to be able to do the same thing. I spend lots of time taking care of them right now. But we love being out in nature hiking, skiing, and kayaking and enjoying what the Earth gives us.

      Sally: It’s also fun to see that “aha” moment in your children when they start to learn a little bit about science and they get the idea that you really can discover things by observing closely. I don’t know if they realize they benefit from having parents who think that way, but I think that also stays with them through their lives.

      Desirée: My son is just waiting for the phone call to be able to be part of MIT’s toy design class.

      Sally: That’s fantastic.

      Desirée: As an official evaluator. Yes.

      Sally: In the last five years or so, we’ve been through the pandemic. In practical terms, how you think about your work and your life, what do you do that has improved your life? I always hate the words of “work-life balance” because they’re so intermeshed, but just for the broader community, how have you thought about that?

      Desirée: I’ve been thinking about my Zoom world and how I am still able to do quite a bit of talking to my colleagues and advancing the research mission and talking to my students that I wouldn’t have been able to do. Even pre-pandemic, it would’ve been pretty hard. We’re all really trained to interact more efficiently through these media and mechanisms. I know how to give a good talk on Zoom, for better or worse. I think that that’s been something that has been great.

      In the context of environment, I think a lot of us—this might be cliched at this point—but realize that there are things that we don’t need to get up on a plane for and perhaps we can work on the computer and interact in that way. I think that’s awesome. There’s not much that can replace real, in-person human interaction, but if it means that you can juggle a few more balls in the air and have your family feel valued and yourself feel valued while you’re also valuing your work that thing that is igniting for you, I think that’s a great outcome.

      Sally: I think that’s right. Unfortunately, though, your kids may never know the meaning of a snow day.

      Desirée: You got it.

      Sally: They may be on a remote school whenever we would’ve been home building snow forts.

      Desirée: As a Mainer, I appreciate this fully, and almost had to write a note this year. Just let them go outside.

      Sally: Exactly, exactly. As we’re wrapping up, just thinking about the future of climate work and coming back to the science, I think you’ve thought a lot about what you’re doing and impact on the climate. I’m just wondering, as you look around MIT, where you think we might have some of the greatest impact? How do you think about what some of your colleagues are doing? Because I’m starting to think a lot about what MIT’s real footprint in this area is going to be.

      Desirée: The first thing I want to say is that I think for a long time, the world’s been looking for a silver bullet climate solution. That is not how we got into this problem and it’s not how we’re going to get out of it.

      Sally: Exactly.

      Desirée: We need a thousand BBs. Fortunately, at MIT, there are many thousands of minds that all have something to contribute. I like to impose, especially on the undergraduates and the graduate researchers, our student population out there, think, “How can I bring my talents to bear on this really most pressing and important problem that’s facing our world right now?” I would say just whatever your skill is and whatever your passion is, try to find a way to marry those things together and find a way to have impact.

      The other thing I would say is that we think really differently about problems. That’s what might be needed. If you’re going to break systems, you need to come at it from a different perspective or a different angle. Encouraging people to think differently, as this community does so well, I think is going to be an enormous asset in bringing some solutions to the climate change challenge.

      Sally: Excellent. If you look back over your career, and even earlier than when you became a faculty member, what do you think the best advice is that you’ve ever been given?

      Desirée: There’s so much. I’ve been fortunate to have a lot of really great mentors. What is the best piece of advice? I think this notion of balancing work and not work. I’ve gotten two really key points of advice. One is about travel. I think that ties into this concept of COVID and whether now we can actually go remote for a lot of things. It was from an MIT professor. He said, “You know, the biggest thing you can do to protect your personal life and your life with your family is to say no and travel less. Travel eats up time on the front, in the back, and it’s your family that’s paying the price for that, so be really judicious about your choices.” That was excellent advice for me.

      Another female faculty member of mine said, “You have to prioritize your family like they are an appointment on your calendar and it’s okay when you do that.” I think those have been really helpful for me as I navigate and struggle with my own very mission-oriented self where I want to keep working and put my focus there, but know that it’s okay to maybe go for a walk and talk to real people.

      Sally: Go wild.

      Desirée: Yes, that’s right.

      Sally: This issue, actually, of saying no, not only to travel but thinking about where you really place your efforts and when there’s a finite amount of time. When I think about this—and advising junior faculty in terms of service—every faculty member is going to be asked way more things than they’re going to want to do. Yet, their service to the department, service to the Institute, is important, not only for their advancement but in how we create a community. I always advise people to say yes to the things they’re truly interested in and they’re passionate about, and there will be enough of those things.

      Desirée: I have a flowchart for when to say yes and when to say no. Having an interest is at the top of the list and then feeling like you’re going to have an impact. That’s something I think, when we do this service at MIT, we really are able to have an impact. It’s not just the oldest people in the room that get to drive the bus. They’re really listening and want to hear that perspective from everybody.

      Sally: That’s excellent. Thanks again, Desirée. I really enjoyed that conversation. To our audience, thanks again for listening to Curiosity Unbounded. I very much hope you’ll all join us again. I’m Sally Kornbluth. Stay curious. More
