    Andrea Lo ’21 draws on ecological lessons for life, work, and education

    Growing up in Los Angeles about 10 minutes away from the Ballona Wetlands, Andrea Lo ’21 has long been interested in ecology. She witnessed, in real-time, the effects of urbanization and the impacts that development had on the wetlands. 

    “In hindsight, it really helped shape my need for a career — and a life — where I can help improve my community and the environment,” she says.

    Lo, who majored in biology at MIT, says a recurring theme in her life has been the pursuit of balance, valuing both extracurricular and curricular activities. She always felt an equal pull toward STEM and the humanities, toward wet lab work and field work, and toward doing research and helping her community. 

    “One of the most important things I learned in 7.30[J] (Fundamentals of Ecology) was that there are always going to be trade-offs. That’s just the way of life,” she says. “The biology major at MIT is really flexible. I got a lot of room to explore what I was interested in and get a good balance overall, with humanities classes along with technical classes.” 

    Lo was drawn to MIT because of the focus on hands-on work — but many of the activities Lo was hoping to do, both extracurricular and curricular, were cut short because of the pandemic, including her lab-based Undergraduate Research Opportunities Program (UROP) project. 

    Instead, she pursued a UROP with MIT Sea Grant, working on a project in partnership with Northeastern University and the Charles River Conservancy with funding support from the MIT Community Service fund as part of STEAM Saturday.  

    She was involved in creating Floating Wetland kits, an educational activity directed at students in grades 4 to 6 to help students understand ecological concepts,the challenges the Charles River faces due to urbanization, and how floating wetlands improve the ecosystem. 

    “Our hope was to educate future generations of local students in Cambridge in order for them to understand the ecology surrounding where they live,” she says. 

    In recent years, many bodies of water in Massachusetts have become unusable during the warmer months due to the process of eutrophication: stormwater runoff picks up everything — from fertilizer and silt to animal excrement — and deposits it at the lowest point, which is often a body of water. This leads to an excess of nutrients in the body of water and, when combined with warm temperatures, can lead to harmful algal blooms, making the water sludgy, bright green, and dangerously toxic. 

    The wetland kits Lo worked with were mini ecosystems, replicating a full-sized floating wetland. One such floating wetland can be seen from the Longfellow Bridge at one end of MIT’s campus — the Charles River floating wetland is a patch of grass attached to a buoy like a boat, which is often visited by birds and inhabited by much smaller critters that cannot be seen from the shore.  

    The Charles River floating wetland has a variety of flora, but the kits Lo helped present use only wheat grass because it is easy to grow and has long, dangling roots that could penetrate the watery medium below. A water tray beneath the grass — the Charles river of the mini ecosystem — contains spirulina powder for replicating algae growth and daphnia, which are small, planktonic crustaceans that help keep freshwater clean and usable. 

    “This work was really fulfilling, but it’s also really important, because environmental sustainability relies on future generations to carry on the work that past generations have been doing,” she says. “MIT’s motto is ‘mens et manus’ — education for practical application, and applying theoretical knowledge to what we do in our daily lives. I think this project really helped reinforce that.” 

    Since 2021, Lo has been working in Denmark in a position she learned about through the MIT-Denmark program. 

    She chose Denmark because of its reputation for environmental and sustainability issues and because she didn’t know much about it except for it being one of the happiest countries in the world, often thought of synonymously with the word “hygge,” which has no direct translation but encapsulates coziness and comfort from the small joys in life. 

    “At MIT, we have a very strong work-hard, play-hard culture. I think we can learn a lot from the work-life balance that Denmark has a reputation for,” she says. “I really wanted to take the opportunity in between graduation and whatever came after to explore beyond my bubble. For me, it was important to step back, out of my comfort zone, step into a different environment — and just live.”

    Currently, her personal project is comparing the conditions of two lagoons on the island of Fyn in Denmark. Both are naturally occurring, but in different states of environmental health. 

    She’s been doing a mix of field work and lab work. She collects sediment and fauna samples using a steel corer, or “butter stick” in her lab’s slang. In the same way that one can use a metal tube-shaped tool to remove the core of an apple, she punches the steel corer into the ground, removing a plug of sample. She then sifts the sample through 1 millimeter mesh, preserves the filtered sample in formalin, and takes everything back to the lab. 

    Once there, she looks through the sample to find macrofauna — mollusks, barnacles, and polychaetes, a bristly-looking segmented worm, for example. Collected over time, sediment characteristics like organic matter content, sediment grain size, and the size and abundance of macrofauna, can reveal trends that can help determine the health of the ecosystem. 

    Lo doesn’t have any concrete results yet, but her data could help researchers project the recovery of a lagoon that was rehabilitated using a technique called managed realignment, where water is allowed to reclaim areas where it was once found. She says she’s glad she gets a mix of field work and lab work, even on Denmark’s stormiest days. 

    “Sometimes there are really cold days where it’s windy and I wish I was in the lab, but, at the same time, it’s nice to have a balance where I can be outside and really be hands-on with my work,” she says.  

    Reflecting her dual interests in the technical and the innovative, she will be back in the Greater Boston area in the fall, pursuing a master of science in innovation and management and an MS in civil and environmental engineering at the Tufts Gordon Institute.

    “So much has happened and changed due to the pandemic that it’s easy to dwell on what could’ve been, but I tell myself to be optimistic and take the positive aspects that have come out of the circumstances,” Lo says. “My opportunities with the Sea Grant, MISTI, and Tufts definitely wouldn’t have happened if the pandemic hadn’t happened.” More

    MIT speaker series taps into students’ passion for entrepreneurship and social impact.

    Last summer, leaders of MIT’s Venture Mentoring Service (VMS) noticed a growing trend in entrepreneur applications to the program: An increasing number of aspiring founders were expressing a passion for social impact.

    VMS, which connects students and alumni with teams of mentors, hosts bootcamps, holds expert office hours, and offers an annual Demo Day, did not previously have offerings to help founders focused on this type of impact, so its leaders decided to pilot an Impact Speaker Series.

    The series, which featured experienced early-stage entrepreneurs from the MIT community and took place throughout the year, was a smashing success. In total, more than 1,200 MIT community members registered across eight events, including students at all stages of their education as well as alumni interested in making a positive impact on the world through entrepreneurship.

    “We felt an intense desire from attendees to explore entrepreneurship as a path to solve our most pressing problems,” VMS mentor and series co-Lead Paul Bosco says. “The degree to which students identified with challenges such as climate, health, sustainability, and education, rather than their major, was striking. Our goal was to help them see a path as first-time founders.”

    Now VMS is riding the momentum from the speaker series by rolling out more support services for impact-driven students, including hosting additional events, adding experienced impact entrepreneurs and social enterprise experts to its network of mentors, and connecting with more funders and executives with experience leading organizations focused on impact.

    Ultimately, VMS believes these new efforts will bolster MIT’s broader mission of translating science and innovation from its labs and classrooms into positive advances around the world.

    “Our pivot to strengthen support for founders with a passion for impact is absolutely aligned with the mission of MIT,” Bosco says. “Pursuing research and ideas with a passion for world-changing impact has always been in the DNA of MIT. A new generation of entrepreneurs is challenging us to help them hone their skills and lead organizations to build a better world.”

    Striking a chord

    Each one of VMS’ events had a different theme, from addressing general founder challenges, like first time pre-seed or nondilutive fundraising to building startup ventures in sectors like climate, health care, and education. One panel focused on helping entrepreneurs find their personal paths to success and impact, featuring founders leading impactful companies at different stages of development. Another panel discussion, titled Funding Your Path to Impact and Success, featured investors and directors of programs funding ventures delivering impact.

    “I want to encourage founders to consider driving toward a new ‘unicorn success’ model, where success is not measured in $1-billion-dollar valuations, but is based on world-changing carbon reductions, water cleanliness, lives saved, students inspired, etc.,” Ela Mirowski, a program director with the National Science Foundation, told the audience at one event.

    In total, the events featured 24 expert speakers, early-stage founders, and funders. Impact driven businesses, speakers emphasized, can take many forms. Bosco, who moderated one of the panels, says he’s heard from students and alumni interested in starting for-profit companies focused on profit and impact, what he called “dual bottom lines,” as well as students interested in starting public benefit companies, social enterprises, and traditional nonprofit organizations.

    “VMS is getting better at tapping into the different types of entrepreneurs at different stages of their journeys,” says Akshit Singla SM ’22. “It’s exactly what’s needed, and I know that because there was a huge waitlist for these events.”

    Zahra Kanji, who attended VMS’s most recent event in May and is currently director of MIT Hacking Medicine, sees the speaker series as a natural response to evolving student needs.

    “For students, I think the focus has changed a lot over the years,” Kanji said. “There used to be a lot more interest in entrepreneurship with making money as the final goal, and now it’s turned into more of a triple goal, like a public benefit corporation or something that has more impact. So, hearing key lessons learned from experts is really important — these aren’t answers you can get in a textbook.”

    Listening to the community

    Many of next year’s VMS events will be similar to the events that most resonated with the MIT community this year. VMS will also be adding an event on entrepreneurship in artificial intelligence and computing for impact. VMS is hoping to continue expanding student connections to recent founders, or what Bosco refers to as “near-peer founders,” that can relate more closely with first-time founders navigating the current startup environment.

    “Given that many new entrepreneurs are shifting to focus on impact, we need to evolve,” says VMS mentor Matt Cherian SM ’11. “I’m glad students are starting to think differently, and I’m really glad VMS is making this programming to help people think in this new way.”

    “The most notable aspect of our series was the commitment of students, including undergrads, graduates, and postdocs, pursuing their passion for impact through entrepreneurship,” Bosco says. “Many students we met exploring entrepreneurship for impact have exceptional job offers from top employers, or if they are alums they’re leaving significant positions to pursue a greater purpose in their lives. It is profoundly inspiring and an honor to help each of these founders.” More

    A clean alternative to one of the world’s most common ingredients

    Never underestimate the power of a time crunch.

    In 2016, MIT classmates David Heller ’18, Shara Ticku, and Harry McNamara PhD ’19 were less than two weeks away from the deadline to present a final business plan as part of their class MAS.883 (Revolutionary Ventures: How to Invent and Deploy Transformative Technologies). The students had connected over a shared passion for using biology to solve climate challenges, but their first few ideas didn’t pan out, so they went back to the drawing board.

    In a brainstorming session, Ticku began to reminisce about a trip to Singapore she’d taken where the burning of forests had cast a dark haze over the city. The story sparked a memory from halfway across the world in Costa Rica, where McNamara had traveled and noticed endless rows of palm plantations, which are used to harvest palm oil.

    “Besides Shara’s experience in Singapore and Harry’s in Costa Rica, palm was a material none of us had seriously thought about,” Heller recalls. “That conversation made us realize it was a big, big industry, and there’s major issues to the way that palm is produced.”

    The classmates decided to try using synthetic biology to create a sustainable alternative to palm oil. The idea was the beginning of C16 Biosciences. Today C16 is fulfilling that mission at scale with a palm oil alternative it harvests from oil-producing yeast, which ferment sugars in a process similar to brewing beer.

    The company’s product, which it sells to personal care brands and directly to consumers, holds enormous potential to improve the sustainability of the personal care and food industries because, as it turns out, the classmates had stumbled onto a massive problem.

    Palm oil is the most popular vegetable oil in the world. It’s used in everything from soaps and cosmetics to sauces, rolls, and crackers. But palm oil can only be harvested from palm trees near the equator, so producers often burn down tropical rainforests and swamps in those regions to make way for plantations, decimating wildlife habitats and producing a staggering amount of greenhouse gas emissions. One recent study found palm expansion in Southeast Asia could account for 0.75 percent of the world’s total greenhouse gas emissions. That’s not even including the palm expansion happening across west Africa and South America. Among familiar creatures threatened by palm oil deforestation are orangutans, all three species of which are now listed as “critically endangered” — the most urgent status on the IUCN Red List of Threatened Species, a global endangered species list.

    “To respond to increasing demand over the last few decades, large palm producers usually inappropriately seize land,” Heller explains. “They’ll literally slash and burn tropical rainforests to the ground, drive out indigenous people, they’ll kill or drive out local wildlife, and they’ll replace everything with hectares and hectares of palm oil plantations. That land conversion process has been emitting something like a gigaton of CO2 per year, just for the expansion of palm oil.”

    From milliliters to metric tons

    Heller took Revolutionary Ventures his junior year as one of the few undergraduates in the Media Lab-based class, which is also open to students from nearby colleges. On one of the first days, students were asked to stand in front of the class and explain their passions, or “what makes them tick,” as Heller recalls. He focused on climate tech.

    McNamara, who was a PhD candidate in the Harvard-MIT Program in Health Sciences and Technology at the time, talked about his interest in applying new technology to global challenges in biotech and biophysics. Ticku, who was attending Harvard Business School, discussed her experience working in fertility health and her passion for global health initiatives. The three decided to team up.

    “The core group is very, very passionate about using biology to solve major climate problems,” says Heller, who majored in biological engineering while at MIT.

    After a successful final presentation in the class, the founders received a small amount of funding by participating in the MIT $100K Pitch Competition and from the MIT Sandbox Innovation Fund.

    “MIT Sandbox was one of our first bits of financial support,” Heller says. “We also received great mentorship. We learned from other startups at MIT and made connections with professors whom we learned a lot from.”

    By the time Heller graduated in 2018, the team had experimented with different yeast strains and produced a few milliliters of oil. The process has gradually been optimized and scaled up from there. Today C16 is producing metric tons of oil in 50,000-liter tanks and has launched a consumer cosmetic brand called Palmless.

    Heller says C16 started its own brand as a way to spread the word about the harms associated with palm oil and to show larger companies it was ready to be a partner.

    “The oil palm tree is amazing in terms of the yields it generates, but the location needed for the crop is in conflict with what’s essential in our ecosystem: tropical rainforests,” Heller says. “There’s a lot of excitement when it comes to microbial palm alternatives. A lot of brands have been under pressure from consumers and even governments who are feeling the urgency around climate and are feeling the urgency from consumers to make changes to get away from an oil ingredient that is incredibly destructive.”

    Scaling with biology

    C16’s first offering, which it calls Torula Oil, is a premium product compared to traditional palm oil, but Heller notes the cost of palm oil today is deflated because companies don’t factor in its costs to the planet and society. He also notes that C16 has a number of advantages in its quest to upend the $60 billion palm oil industry: It’s far easier to improve the productivity of C16’s precision fermentation process than it is to improve agricultural processes. C16 also expects its costs to plummet as it continues to grow.

    “What’s exciting for us is we have these economies of scale,” Heller says. “We have the opportunity to expand vertically, in large stainless steel tanks, as opposed to horizontally on land, so we can drive down our cost curve by increasing the size of the infrastructure and improving the optimization of our strain. The timelines for improvement in a precision fermentation process are a fraction of the time it takes in an agricultural context.”

    Heller says C16 is currently focused on partnering with large personal care brands and expects to announce some important deals in coming months. Further down the line, C16 also hopes to use its product to replace the palm oil in food products, although additional regulations mean that dream is still a few years away.

    With all of its efforts, C16 tries to shine a light on the problems associated with the palm industry, which the company feels are underappreciated despite palm oil’s ubiquitous presence in our society.

    “We need to find a way to reduce our reliance on deforestation products,” Heller says. “We do a lot of work to help educate people on the palm oil industry. Just because something has palm oil in it doesn’t mean you should stop using it, but you should understand what that means for the world.” More

    Preparing Colombia’s cities for life amid changing forests

    It was an uncharacteristically sunny morning as Marcela Angel MCP ’18, flanked by a drone pilot from the Boston engineering firm AirWorks and a data collection team from the Colombian regional environmental agency Corpoamazonia, climbed a hill in the Andes Mountains of southwest Colombia. The area’s usual mountain cloud cover — one of the major challenges to working with satellite imagery or flying UAVs (unpiloted aerial vehicles, or drones) in the Pacific highlands of the Amazon — would roll through in the hours to come. But for now, her team had chosen a good day to hike out for their first flight. Angel is used to long travel for her research. Raised in Bogotá, she maintained strong ties to Colombia throughout her master’s program in the MIT Department of Urban Studies and Planning (DUSP). Her graduate thesis, examining Bogotá’s management of its public green space, took her regularly back to her hometown, exploring how the city could offer residents more equal access to the clean air, flood protection and day-to-day health and social benefits provided by parks and trees. But the hill she was hiking this morning, outside the remote city of Mocoa, had taken an especially long time to climb: five years building relationships with the community of Mocoa and the Colombian government, recruiting project partners, and navigating the bureaucracy of bringing UAVs into the country. Now, her team finally unwrapped their first, knee-high drone from its tarp and set it carefully in the grass. Under the gathering gray clouds, the buzz of its rotors joined the hum of insects in the trees, and the machine at last took to the skies.

    From Colombia to Cambridge

    “I actually grew up on the last street before the eastern mountains reserve,” Angel says of her childhood in Bogotá. “I’ve always been at that border between city and nature.” This idea, that urban areas are married to the ecosystems around them, would inform Angel’s whole education and career. Before coming to MIT, she studied architecture at Bogotá’s Los Andes University; for her graduation project she proposed a plan to resettle an informal neighborhood on Bogotá’s outskirts to minimize environmental risks to its residents. Among her projects at MIT was an initiative to spatially analyze Bogotá’s tree canopy, providing data for the city to plan a tree-planting program as a strategy to give vulnerable populations in the city more access to nature. And she was naturally intrigued when Colombia’s former minister of environment and sustainable development came to MIT in 2017 to give a guest presentation to the DUSP master’s program. The minister, Luis Gilberto Murillo (now the Colombian ambassador to the United States), introduced the students to the challenges triggered by a recent disaster in the city of Mocoa, on the border between the lowland Amazon and the Andes Mountains. Unprecedented rainstorms had destabilized the surrounding forests, and that April a devastating flood and landslide had killed hundreds of people and destroyed entire neighborhoods. And as climate change contributed to growing rainfall in the region, the risks of more landslide events were rising. Murillo provided useful insights into how city planning decisions had contributed to the crisis. But he also asked for MIT’s support addressing future landslide risks in the area. Angel and Juan Camilo Osorio, a PhD candidate at DUSP, decided to take up the challenge, and in January 2018 and 2019, a research delegation from MIT traveled to Colombia for a newly-created graduate course. Returning once again to Bogotá, Angel interviewed government agencies and nonprofits to understand the state of landslide monitoring and public policy. In Mocoa, further interviews and a series of workshops helped clarify what locals needed most and what MIT could provide: better information on where and when landslides might strike, and a process to increase risk awareness and involve traditionally marginalized groups in decision-making processes around that risk. Over the coming year, a core team formed to put the insights from this trip into action, including Angel, Osorio, postdoc Norhan Bayomi of the MIT Environmental Solutions Initiative (ESI) and MIT Professor John Fernández, director of the ESI and one of Angel’s mentors at DUSP. After a second visit to Mocoa that brought into the fold Indigenous groups, environmental agencies, and the national army, a plan was formed: MIT would partner with Corpoamazonia and build a network of community researchers to deploy and test drone technology and machine learning models to monitor the mountain forests for both landslide risks and signs of forest health, while implementing a participatory planning process with residents. “What our projects aim to do is give the communities new tools to continue protecting and restoring the forest,” says Angel, “and support new and inclusive development models, even in the face of new challenges.”

    Lifelines for the climate

    The goal of tropical forest conservation is an urgent one. As forests are cut down, their trees and soils release carbon they have stored over millennia, adding huge amounts of heat-trapping carbon dioxide to the atmosphere. Deforestation, mainly in the tropics, is now estimated to contribute more to climate change than any country besides the United States and China — and once lost, tropical forests are exceptionally hard to restore. “Tropical forests should be a natural way to slow and reverse climate change,” says Angel. “And they can be. But today, we are reaching critical tipping points where it is just the opposite.” This became the motivating force for Angel’s career after her graduation. In 2019, Fernández invited her to join the ESI and lead a new Natural Climate Solutions Program, with the Mocoa project as its first centerpiece. She quickly mobilized the partners to raise funding for the project from the Global Environmental Facility and the CAF Development Bank of Latin America and the Caribbean, and recruited additional partners including MIT Lincoln Laboratories, AirWorks, and the Pratt Institute, where Osorio had become an assistant professor. She hired machine learning specialists from MIT to begin design on UAVs’ data processing, and helped assemble a local research network in Mocoa to increase risk awareness, promote community participation, and better understand what information city officials and community groups needed for city planning and conservation. “This is the amazing thing about MIT,” she says. “When you study a problem here, you’re not just playing in a sandbox. Everyone I’ve worked with is motivated by the complexity of the technical challenge and the opportunity for meaningful engagement in Mocoa, and hopefully in many more places besides.” At the same time, Angel created opportunities for the next generation of MIT graduate students to follow in her footsteps. With Fernández and Bayomi, she created a new course, 4.S23 (Biodiversity and Cities), in which students traveled to Colombia to develop urban planning strategies for the cities of Quidbó and Leticia, located in carbon-rich and biodiverse areas. The course has been taught twice, with Professor Gabriella Carolini joining the teaching team for spring 2023, and has already led to a student report to city officials in Quidbó recommending ways to enhance biodiversity and adapt to climate change as the city grows, a multi-stakeholder partnership to train local youth and implement a citizen-led biodiversity survey, and a seed grant from the MIT Climate and Sustainability Consortium to begin providing both cities detailed data on their tree cover derived from satellite images. “These regions face serious threats, especially on a warming planet, but many of the solutions for climate change, biodiversity conservation, and environmental equity in the region go hand-in-hand,” Angel says. “When you design a city to use fewer resources, to contribute less to climate change, it also causes less pressure on the environment around it. When you design a city for equity and quality of life, you’re giving attention to its green spaces and what they can provide for people and as habitat for other species. When you protect and restore forests, you’re protecting local bioeconomies.”

    Bringing the data home

    Meanwhile, in Mocoa, Angel’s original vision is taking flight. With the team’s test flights behind them, they can now begin creating digital models of the surrounding area. Regular drone flights and soil samples will fill in changing information about trees, water, and local geology, allowing the project’s machine learning specialists to identify warning signs for future landslides and extreme weather events. More importantly, there is now an established network of local community researchers and leaders ready to make use of this information. With feedback from their Mocoan partners, Angel’s team has built a prototype of the online platform they will use to share their UAV data; they’re now letting Mocoa residents take it for a test drive and suggest how it can be made more user-friendly. Her visit this January also paved the way for new projects that will tie the Environmental Solutions Initiative more tightly to Mocoa. With her project partners, Angel is exploring developing a course to teach local students how to use UAVs like the ones her team is flying. She is also considering expanded efforts to collect the kind of informal knowledge of Mocoa, on the local ecology and culture, that people everywhere use in making their city planning and emergency response decisions, but that is rarely codified and included in scientific risk analyses. It’s a great deal of work to offer this one community the tools to adapt successfully to climate change. But even with all the robotics and machine learning models in the world, this close, slow-unfolding engagement, grounded in trust and community inclusion, is what it takes to truly prepare people to confront profound changes in their city and environment. “Protecting natural carbon sinks is a global socio-environmental challenge, and one where it is not enough for MIT to just contribute to the knowledge base or develop a new technology,” says Angel. “But we can help mobilize decision-makers and nontraditional actors, and design more inclusive and technology-enhanced processes, to make this easier for the people who have lifelong stakes in these ecosystems. That is the vision.” More

    Arina Khotimsky ’23 awarded 2023 Michel David-Weill Scholarship

    Arina Khotimsky ’23 was selected for the 2023 Michel David-Weill scholarship, awarded each year to one student from the United States in a master’s program at Sciences Po in France who exemplifies the core values embodied by its namesake: excellence, leadership, multiculturalism, and high achievement. This fall Khotimsky will enter the master’s program in international energy, which is part of Sciences Po’s Paris School of International Affairs. The program aims to provide a holistic understanding of energy issues, across disciplines and across all energy sources.

    Khotimsky graduated this year from MIT with a major in materials science and engineering, and minors in energy studies and in French.

    Asked what drew her to her major, Khotimsky talked about her love of the outdoors. Seeing effects of climate change on the world around made her made her want to explore solutions. “I settled on material science and engineering because there’s so many different applications: whether it be solar power, developing different battery materials and chemistries, or some other technology. Getting that technical background at MIT can help me understand how we can implement solutions around the world, with diverse cultures in mind.”

    One of Khotimsky’s material sciences professors, Polina Anikeeva, observes that “Arina possesses the spirit of creativity, optimism, and unparalleled work ethic — all necessary ingredients to solve energy and climate challenges of our century.”

    Khotimsky is well aware of the big stakes in discussions around energy policy. She explains, “We have to cooperate internationally to make a dent in carbon emissions. The United States is historically the biggest CO2 emitter and has a large role to play to transition to a more sustainable future.”

    Her interest in studying climate change solutions on a world scale also converged with her interest in studying other languages and cultures. Her main language studies at MIT have been in French, although she also speaks Russian and beginner Chinese.

    Due to her achievement in MIT French classes, Khotimsky was one of nine students selected for a two-week cultural immersion program in Paris last June, led by MIT Professor Bruno Perreau. Perreau also had her in class last fall, and spoke about the energy and commitment she brought to class, describing her as “one of my very best students since I started to teach 22 years ago.” Khotimsky is excited to be living in France for her master’s program and putting her French skills to work.

    Khotimsky’s impressive undergraduate career has also included being co-president of the MIT Energy and Climate Club, and participating in the MIT delegation to 2022 Conference of the Parties summit (COP27) of the United Nations in Egypt last November. She also participated in the NEET Decarbonizing Ulaanbaatar project, traveling to Mongolia in Independent Activities Period 2023 with a group of students and instructors to work on clean heating technologies for traditional ger homes.

    In addition to her academic work and other extracurricular activities, Khotimsky was also a member of the MIT women’s rowing team. She walked onto the team as a first-year student, making it into the Varsity 8 boat for her senior season. Holly Metcalf, MIT women’s varsity openweight rowing coach, explains, “Being on the rowing team has in many ways become a metaphor for what Arina has come to study … She realized that rowing is about so much more than physics — it is about who one must become as an individual to contribute to the sum of mental and physical strength of the entire team.” Khotimsky was recognized on May 22 by the Patriot League, who named her the 2023 Patriot League Women’s Rowing Scholar-Athlete of the Year.

    Looking ahead, Khotimsky envisions her future involving international energy negotiations or policy. “The master’s degree I’m pursuing in international relations will help me develop skills to communicate with stakeholders from around the world and figure out how to implement solutions globally.” More

    Civil discourse project to launch at MIT

    A new project on civil discourse aims to promote open and civil discussion of difficult topics on the MIT campus.

    The project, which will launch this fall, includes a speaker series and curricular activities in MIT’s Concourse program for first-year students. MIT philosophers Alex Byrne and Brad Skow from the Department of Linguistics and Philosophy lead the project, in close coordination with Anne McCants, professor of history and director of Concourse, and Linda Rabieh, a Concourse lecturer. 

    The Arthur Vining Davis Foundations provided a substantial grant to help fund the project. Promoting civil discourse on college campuses is an area of focus for AVDF — they sponsor related projects at many schools, including Duke University and Davidson College.

    The first event in the speaker series is planned for the evening of Oct. 24, on the question of how we should respond to climate change. The two speakers are Professor Steven Koonin (New York University, ex-provost of Caltech, and an MIT alum) and MIT Professor Kerry Emanuel from the Department of Earth, Atmospheric, and Planetary Sciences. Eight such events are planned over two years. Each will feature speakers discussing difficult or controversial topics, and will aim to model civil debate and dialogue involving experts from inside and outside the MIT community. 

    Byrne and Skow said that the project is meant to counterbalance a growing unwillingness to listen to others or to tolerate the expression of certain ideas. But the goal, says Byrne, “is not to platform heterodox views for their own sake, or to needlessly provoke. Rather, we want to platform collegial, informed conversations on important matters about which there is reasonable disagreement.” 

    Faculty at MIT voted last fall to adopt a statement on free expression, following a report written by an MIT working group. The project organizers want to build on that vote and the report. “The free expression statement says that discussion of controversial topics should not be prohibited or punished,” Skow says, “but the longer working-group report goes farther, urging MIT to promote free expression. This project is an attempt to do that — to show that open discussion and open inquiry are valuable.” 

    “It has the potential to generate lively, constructive, respectful discussion on campus and to show by example both that controversial views are not suppressed at MIT and that we learn by engaging with them openly,” says Kieran Setiya, the head of MIT Philosophy. Agustín Rayo, dean of the School of Humanities and Social Sciences, thinks that the project can “play a critical role in demonstrating — to faculty, students, staff, alumni, and friends — the Institute’s commitment to free speech and civil discourse.”

    Apart from climate change, topics for the first series of events include feminism and progress (Nov. 9, with Mary Harrington, author of “Feminism against Progress”), and Covid public health policy (Feb. 26, with Vinay Prasad, professor of epidemiology and biostatistics at the University of California at San Francisco). Organizers say they hope the speaker series becomes a permanent part of MIT’s intellectual life after the grant period. To amplify the work to an audience beyond MIT, the project organizers have partnered with the Johns Hopkins University political scientist Yascha Mounk and his team at Persuasion to produce podcast episodes around the speaker events. They will air as special episodes of Mounk’s podcast “The Good Fight.” 

    The Concourse component of the project will take advantage of the small learning community setting to develop the tools and experience for productive disagreement. 

    “The core mission of Concourse depends on both the principle of free expression and the practice of civil discourse,” says McCants, “making it a natural springboard for promoting both across the intellectual culture of MIT.”  

    Concourse will experiment with, among other things, seminars discussing the history and practice of freedom of expression, roundtable discussions, and student-led debates. Braver Angels, an organization with the mission of reducing political polarization, is another partner, along with Persuasion. 

    “Our goal,” says Rabieh, “is to facilitate, in collaboration with Braver Angels, the probing, intense, and often difficult conversations that lie at the heart of the Concourse program and that are the hallmark of education.” More

    Will the charging networks arrive in time?

    For many owners of electric vehicles (EVs), or for prospective EV owners, a thorny problem is where to charge them. Even as legacy automakers increasingly invest in manufacturing more all-electric cars and trucks, there is not a dense network of charging stations serving many types of vehicles, which would make EVs more convenient to use.

    “We’re going to have the ability to produce and deliver millions of EVs,” said MIT Professor Charles Fine at the final session this semester of the MIT Mobility Forum. “It’s not clear we’re going to have the ability to charge them. That’s a huge, huge mismatch.”

    Indeed, making EV charging stations as ubiquitous as gas stations could spur a major transition within the entire U.S. vehicle fleet. While the automaker Tesla has built a network of almost 2,000 charging stations across the U.S., and might make some interoperable with other makes of vehicles, independent companies trying to develop a business out of it are still trying to gain significant traction.

    “They don’t have a business model that works yet,” said Fine, the Chrysler Leaders for Global Operations Professor of Management at the MIT Sloan School of Management, speaking of startup firms. “They haven’t figured out their supply chains. They haven’t figured out the customer value proposition. They haven’t figured out their technology standards. It’s a very, very immature domain.”

    The May 12 event drew nearly 250 people as well as an online audience. The MIT Mobility Forum is a weekly set of talks and discussions during the academic year, ranging widely across the field of transportation and design. It is hosted by the MIT Mobility Initiative, which works to advance sustainable, accessible, and safe forms of transportation.

    Fine is a prominent expert in the areas of operations strategy, entrepreneurship, and supply chain management. He has been at MIT Sloan for over 30 years; from 2015 to 2022, he also served as the founding president, dean, and CEO of the Asia School of Business in Kuala Lumpur, Malaysia, a collaboration between MIT Sloan and Bank Negara Malaysia. Fine is also author of “Faster, Smarter, Greener: The Future of the Car and Urban Mobility” (MIT Press, 2017).

    In Fine’s remarks, he discussed the growth stages of startup companies, highlighting three phases where firms try to “nail it, scale it, and sail it” — that is, figure out the concept and workability of their enterprise, try to expand it, and then operate as a larger company. The charging-business startups are still somewhere within the first of these phases.

    At the same time, the established automakers have announced major investments in EVs — a collective $860 billion over the next decade, Fine noted. Among others, Ford says it will invest $50 billion in EV production by 2026; General Motors plans to spend $35 billion on EVs by 2025; and Toyota has announced it will invest $35 billion in EV manufacturing by 2030.

    With all these vehicles potentially coming to market, Fine suggested, the crux of the issue is a kind of “chicken and egg” problem between EVs and the network needed to support them.

    “If you’re a startup company in the charging business, if there aren’t many EVs out there, you’re not going to be making much money, and that doesn’t give you the capital to continue to invest and grow,” Fine said. “So, they need to wait until they have revenue before they can grow further. On the other hand, why should anybody buy an electric car if they don’t think they’re going to be able to charge it?”

    Those living in single-family homes can install chargers. But many others are not in that situation, Fine noted: “For people who don’t have fixed parking spaces and have to rely on the public network, there is this chicken-and-egg problem. They can’t buy an EV unless they know how they’re going to be able to charge it, and charging companies can’t build out their networks unless they know how they’re going to get their revenue.”

    The event featured a question-and-answer session and audience discussion, with a range of questions, and comments from some industry veterans, including Robin Chase SM ’86, the co-founder and former CEO of Zipcar. She expressed some optimism that startup charging companies will be able to get traction in the nascent market before long.

    “The right companies can learn very fast,” Chase said. “There’s no reason why they can’t correct those scaling problems in short-ish order.”

    In answer to other audience questions, Fine noted some of the challenges that will have to be addressed by independent charging firms, such as unified standards and interoperability among automakers and charging stations.

    “For a driver to have to have six different apps, or [their] car doesn’t fit in the plug here or there, or my software doesn’t talk to my credit card … connectivity, standards, technical issues need to be worked out as well,” Fine said.

    There are also varying regulatory issues, including grid policies and what consumers can be billed for, which have to be worked out on a state-by-state basis, meaning that even modest-size startups will have to have knowledgeable and productive legal departments.

    All of which makes it possible, as Fine suggested, that the large legacy automakers will start investing more heavily in the charging business in the near future. Mercedes, he noted, just announced in January that it is entering into a partnership with charging firms ChargePoint and MN8 Energy to develop about 400 charging stations across North America by 2027. By necessity, others might have to follow suit if they want to protect their massive planned investments in the EV sector.

    “I’m not in the business of telling [automakers] what to do, but I do think they have a lot at risk,” Fine said. “They’re spending billions and billions of dollars to produce these cars, and I don’t think they can afford an epic failure [if] people don’t buy them because there’s no charging infrastructure. If they’re waiting for the startups to build out rapidly, then they may be waiting longer than they hope to wait.” More

    Paula Hammond wins faculty’s Killian Award for 2023-24

    Paula Hammond, a leading innovator in nanotechnology and head of MIT’s Department of Chemical Engineering, has been named the recipient of the 2023-2024 James R. Killian Jr. Faculty Achievement Award.

    Hammond, an MIT Institute Professor, was honored for her work designing novel polymers and nanomaterials, which have extensive applications in fields including medicine and energy.

    “Professor Hammond is a pioneer in nanotechnology research, with a program that spans from basic science to translational research in medicine and energy. She has introduced new approaches for the design and development of complex drug delivery systems for cancer treatment and non-invasive imaging,” according to the award citation, which was read at the May 17 faculty meeting by Laura Kiessling, the chair of the Killian Award Selection Committee and the Novartis Professor of Chemistry at MIT.

    Established in 1971 to honor MIT’s 10th president, James Killian, the Killian Award recognizes extraordinary professional achievements by an MIT faculty member.

    “I’ve been to past Killian Award lectures, and I’ve always thought these were the ultimate achievers at MIT in terms of their work and their science,” Hammond says. “I am incredibly honored and overwhelmed to be considered even close to a part of that group.”

    Hammond, who earned her bachelor’s degree from MIT in 1984, worked as an engineer before returning to the Institute four years later to earn a PhD, which she received in 1993. After two years as a postdoc at Harvard University, she returned to MIT again as a faculty member in 1995.

    “In a world where it isn’t always cool to be heavy into your science and your work, MIT was a place where I felt like I could just be completely myself, and that was an amazing thing,” she says.

    Since joining the faculty, Hammond has pioneered techniques for creating thin polymer films and other materials using layer-by-layer assembly. This approach can be used to build polymers with highly controlled architectures by alternately exposing a surface to positively and negatively charged particles.

    Hammond’s lab uses this technique to design materials for many different applications, including drug delivery, regenerative medicine, noninvasive imaging, and battery technology.

    Her accomplishments include designing nanoparticles that can zoom in on tumors and release their cargo when they associate with cancer cells. She has also developed nanoparticles and thin polymer films that can carry multiple drugs to a specific site and release the drugs in a controlled or staggered fashion. In recent years, much of that work has focused on potential treatments and diagnostics for ovarian cancer.

    “We’ve really had a focus on ovarian cancer over the past several years. My hope is that our work will move us in the direction of understanding how we can treat ovarian cancer, and, in collaboration with my colleagues, how we can detect it more effectively,” says Hammond, who is a member of MIT’s Koch Institute for Integrative Cancer Research.

    The award committee also cited Hammond’s record of service, both to MIT and the national scientific community. She currently serves on the President’s Council of Advisors on Science and Technology, and she is a former member of the U.S. Secretary of Energy Scientific Advisory Board. At MIT, Hammond chaired the Initiative on Faculty Race and Diversity, and co-chaired the Academic and Professional Relationships Working Group and the Implementation Team of the MIT response to the National Academies’ report entitled “Sexual Harassment of Women.”

    Among her many honors, Hammond is one of only 25 scientists who have been elected to the National Academies of Engineering, Sciences, and Medicine.

    Hammond has also been recognized for her dedication to teaching and mentoring. As a reflection of her excellence in those areas, Hammond was awarded the Irwin Sizer Award for Significant Improvements to MIT Education, the Henry Hill Lecturer Award in 2002, and the Junior Bose Faculty Award in 2000. She also co-chaired the recent Ad Hoc Committee on Faculty Advising and Mentoring, and has been selected as a “Committed to Caring” honoree for her work mentoring students and postdocs in her research group.

    “The Selection Committee is delighted to have this opportunity to honor Professor Paula Hammond, not only for her tremendous professional achievements and contributions, but also for her genuine warmth and humanity, her thoughtfulness and effective leadership, and her empathy and ethics. She is someone worth emulating. Indeed, simply put, she is the best of us,” the award committee wrote in its citation. More
