In 2020, Electrical and Computer Engineering Professor Wencong Su was looking for an undergraduate student to assist with a project focused on adding innovative energy efficiency measures to the already LEED-certified Engineering Lab Building. At the time, Su was teaching all graduate courses so he didn’t have many undergrads in his orbit. So Su asked for a little help from one of his graduate assistants, who emailed the job posting to the students in a 200-level lab. LaRico Andres, a sophomore and recent transfer from Henry Ford College, thought it sounded interesting and reached out to Su with his resume. Su remembers Andres didn’t exactly fit the description of the type of student who usually applies for these kinds of opportunities. Andres was a few years older than Su, already had a full-time job working as an instrument tech at the Great Lakes Water Authority, and his GPA at the time wasn’t knocking anyone out. But after the two chatted for a little while, Su offered him the job. Andres was personable, seemed excited to learn, and though he was a research novice, it turned out his background in instrumentation was actually quite relevant to the types of things they would be investigating in the ELB.

Andres excelled on the project and it led to many more opportunities to work alongside Su. On one project supported by the National Science Foundation’s I-Corps — a program that helps researchers translate their laboratory work into marketable products — Andres traveled to conferences in Orlando, San Diego and Austin, completing a flurry of more than 100 interviews with industrial professionals in seven weeks about . On another project, he and Su created an app that used the ELB’s building management software and the utility’s fuel profile to give users an idea of what being a building occupant added to their personal carbon footprint. As you’d expect, Andres picked up a lot of skills working with Su. But as often happens when two people spend a lot of time together, Andres and Su also started talking about things other than their work. Andres jokes that they initially bonded over the fact that they “both like to eat.” But the conversations gradually grew more personal. Both men had daughters, so they talked about their kids. Su shared some of the challenges he faced when he first came to the United States for college and he knew very little English. Andres reciprocated with stories about some challenges he faced growing up in Detroit, not always having enough money to pay all the bills at once, and some things that happened when he was younger that tripped up his plans to go to college earlier in his life.

Su says he enjoyed Andres' perspective — in part, because Su is someone who’s interested in people, and the ups and downs of Andres’ life made for a compelling personal story. In addition, Su says he’s always been interested in Detroit, and through Andres, a lifelong Detroiter, he enjoyed learning about a side of the city that “you don’t hear about on the TV news.” Interestingly, at a certain point, both men noticed that many of their personal conversations weren’t actually that separate from their field of study: energy systems. For example, Andres shared stories about how, in his family, when the power would go out, that meant you didn’t open the fridge so his grandfather’s insulin wouldn’t spoil. Or how, if the power was out long enough, they’d start barbequing the meat they had in the freezer so it wouldn’t go to waste. Or how he and his relatives used to take turns refilling his grandmother’s boiler when she couldn’t afford to fix it right away. “The biggest burden a lot of my people have is energy, whether it’s fuel, gassing up your car going to work, or just trying to keep your house warm,” Andres says. “I know what it’s like to struggle to pay a utility bill and choose between paying that bill on time or buying food. I know people whose furnaces go out and can’t afford to get them fixed. That’s the impact energy has. Energy helps. But if you don't have a lot of money, energy can be a burden.”

Andres’ testimony left an impression on Su, and eventually the two of them started kicking around ideas for projects focused on energy justice, an emerging field that focuses on equity, affordability, accessibility and participation in the energy system and the ongoing transition to new energy technologies. That lens became the cornerstone of their 2023 Summer Undergraduate Research Experience project, in which Andres helped create an interactive mapping tool that explores the connection between historical real estate redlining and disparities in energy access in metro Detroit. Using Andres’ dashboard, a user can quickly toggle through different layers and explore whether a neighborhood is formerly redlined, where current utility outages are and their causes, locations of renewable energy installations and EV charging stations, as well as census data that provides demographic information about the people currently living in the neighborhood. One of the big reveals from Andres’ work is that metro Detroit neighborhoods that were historically redlined tend to be lower-income, non-white, have power outages that tend to be longer, and have less access to renewable energy and EV charging infrastructure. Their work on the app led to an .

After the project, Andres was nearing the end of his undergraduate career, and Su began asking him a little more frequently and persistently if he’d ever thought about grad school. Andres says that honestly wasn’t on his radar when he initially transferred to ������-Dearborn. At that time, his thinking pretty much revolved around the straightforward calculus that getting an engineering degree would help him get a higher-paying job and lead to a more comfortable life for him and his family. But after working in Su’s lab, particularly on the energy justice-focused mapping project, he says his perspective began to change. “If I did the safe thing and got a job, yeah, that would help me. But working with Professor Su helped me see what it is that I really wanted to do. And what I really wanted to do was help people,” Andres says. To do that, Andres decided to take a chance and continue his education, enrolling in the department’s doctoral program, where he’s now continuing his work alongside Su. Andres is still just in his first year of the program, but the pair have already started discussing ideas for Andres’ dissertation research. Not surprisingly, energy justice topics are rising to the top of their list. One idea they’ve been kicking around recently is creating a machine learning-based app that would use weather and outage data to forecast the likelihood of power outages, sort of like the snow day prediction models that have become super popular with parents and kids. “A technology like this could have multiple applications,” Su says. “It could help a utility identify where they need to upgrade their infrastructure to make it more resilient, or where they might need to deploy the most crews ahead of a storm. But it could also directly help people. Like, if you saw that there was a 90% chance you were going to lose your power for five hours tomorrow, people could charge their batteries or make a trip out to get food.” 

Andres says it’s still a little wild to think he’s in a PhD program, and the future he’s contemplating for himself now is much different than the one he was thinking about a few years ago. For the time being, he’d love to continue to do research in the energy justice field and develop innovative ways to help people. He also wants to start a nonprofit that gets young people excited about things like sustainable energy technologies and smart cities. Ultimately, if all goes well, he’d love to be a college professor just like his mentor. “It’s funny, the opportunities that come up in your life,” Andres says. “Like, what if I had ignored that email? What if I hadn’t stepped out and emailed professor Su? He saw something in me that I didn’t even know about myself. And he probably doesn't even know how many other people that’s going to touch. My daughter and little cousins, they all get to see that, ‘Hey, Uncle Rico is gonna be a doctor.’ Because of Professor Su, I’m setting a new example for the people in my life. My wife, sister and other family members, everybody is, like, ‘Wow, you was always smart.’ I just went the long way. And I’m just glad I have an opportunity now to make an impact in the community.” 

That a college professor would have such a profound impact on a student isn’t super surprising. It’s what many faculty shoot to achieve every day. But Su says Andres has also had a big influence on him. On a personal level, he finds Andres' life so inspiring, and admires his work ethic, the personal sacrifices he’s making to be part of the PhD program, and his vision for using research to help people in his community. Their relationship has also had a big influence on Su’s own work. “For example, losing power for one hour in a wealthy neighborhood compared to a disadvantaged neighborhood, it has totally different impacts. Or if you lose power, then that suddenly becomes a food issue for some people. I never really thought about stuff like that before,” Su says. “Now, I'm thinking more about how our research has the potential to help people. Because, otherwise, maybe you’re just publishing a paper with some very fancy solutions and complicated equations. But how are you helping average people?”
