A leg up for STEM majors

MIT undergrads broaden their perspectives and prospects through political science

Senior Kevin Guo, a computer science major, and junior Erin Hovendon, studying mechanical engineering, are on widely divergent paths at MIT. But their lives do intersect in one dimension: They share an understanding that their political science and public policy minors provide crucial perspectives on their research and future careers.

For Guo, the connection between computer science and policy emerged through his work at MIT's Election and Data Science Lab (MEDSL). "When I started, I was just looking for a place to learn how to code and do data science," he reflects. "But what I found was this fascinating intersection where technical skills could directly shape democratic processes."

Hovendon is focused on sustainable methods for addressing climate change. She is currently participating in a multi-semester research project at MIT's Environmental Dynamics (END) Lab developing monitoring technology for marine carbon dioxide removal (mCDR).

She believes the success of her research today and in the future depends on an understanding of its impact on society. Her academic track in policy provides that grounding.  “When you’re developing a new technology, you need to focus as well on how it will be applied,” she says. “This means learning about the policies required to scale it up and about the best ways to convey the value of what you’re working on to the public.”

Bridging STEM and policy

For both Hovendon and Guo, interdisciplinary study is proving to be a valuable platform for tangibly addressing real-world challenges.

Guo came to MIT from Andover, Massachusetts, the son of parents who specialize in semiconductors and computer science. While math and computer science were a natural track for him, Guo was also keenly interested in geopolitics. He enrolled in American Foreign Policy 17.40. "It was my first engagement with MIT political science and I liked it a lot, because it dealt with historical episodes I wanted to learn more about, like World War II, the Korean War and Vietnam," says Guo.

He followed up with a class on American Military History and on the Rise of Asia, where he found himself enrolled with graduate students and active duty US military officers. "I liked attending a course with people who had unusual insights," Guo remarks. "I also liked that these humanities classes were small seminars, and focused a lot on individual students."

From coding to elections

It was in Machine Learning and Data Science in Politics (17.835) that Guo first realized he could directly connect his computer science and math expertise to the humanities. "They gave us big political science
data sets to analyze, which was a pretty cool application of the skills I learned in my major," he says.

Guo springboarded from this class to a three-year, undergraduate research project in the Election and Data Science Lab. "The hardest part is data collection, which I worked on for an election audit project that looked at whether there were significant differences between original vote counts and audit counts in all the states, at the precinct level," says Guo. "We had to scrape data, raw PDFs, and create a unified data set, standardized to our format, that we could publish."

The data analysis skills he acquired in the lab have come in handy in the professional sphere in which he has begun training: investment finance.

"The workflow is very similar: clean the data to see what you want, analyze it, to see if I can find an edge; and then write some code to implement it," he says. "The biggest difference between finance and the
lab research is that the development cycle is a lot faster, where you want to act on a data set in a few days rather than weeks or months."

Engineering environmental solutions

Hovendon, a native of North Carolina with a deep love for the outdoors, arrived at MIT committed "to doing something related to sustainability, and having a direct application in the world around me," she says.

Initially, she headed toward environmental engineering, "but then I realized that pretty much every major can take a different approach to that topic," she says. "So I ended up switching to mechanical
engineering because I really enjoy the hands-on aspects of the field."

In parallel to her design and manufacturing, and mechanics and materials courses, Hovendon also immersed herself in energy and environmental policy classes. One memorable anthropology class, Living through Climate Change (21A.404), asked students to consider whether technological or policy solutions could be fully effective on their own for combating climate change. "It was useful to apply holistic ways of exploring human relations to the environment," says Hovendon.

Hovendon brings this well-rounded perspective to her research at ENDLab in marine carbon capture and fluid dynamics. She is helping to develop verification methods for mCDR at a pilot treatment plant in California. The facility aims to remove 100 tons of CO₂ directly from the ocean by enhancing natural processes. Hovendon hopes to design cost-efficient monitoring systems to demonstrate the efficacy of this new technology. If scaled up, mCDR could enable oceans to store significantly more atmospheric carbon, helping cool the planet.

But Hovendon is well aware that innovation with a major impact cannot emerge on the basis of technical efficacy alone.

"You're going to have people who think that you shouldn't be trying to replicate or interfere with a natural system, and if you're putting one of these facilities somewhere in water, then you're using public spaces
and resources," she says. "It's impossible to come up with any kind of technology, but especially any kind of climate-related technology, without first getting the public to buy into it."

She recalls Making Public Policy (17.30J), which emphasized the importance of both economic and social analysis to the successful passage of highly impactful legislation, such as the Affordable Care Act.

"I think that breakthroughs in science and engineering should be evaluated not just through their technological prowess, but through the success of their implementation for general societal benefit," she says. "Understanding the policy aspects is vital for improving accessibility for scientific advancements."

Beyond the Dome

Guo will soon set out for a career as a quantitative financial trader, and he views his political science background as essential to his success. While his expertise in data cleaning and analysis will come
into play, he believes other skills will as well: "Understanding foreign policy, considering how US policy impacts other places, that's actually very important in finance," he explains. "Macroeconomic changes and politics affect trading volatility and markets in general so it's very important to understand what's going on."

With one year to go, Hovendon is contemplating graduate school in mechanical engineering, perhaps designing renewable energy technologies. "I just really hope that I'm working on something I'm genuinely
passionate about, something that has a broader purpose," she says. "In terms of politics and technology, I also hope that at least some government research and development will still go to climate work,
because I'm sure there will be an urgent need for it."
