When twin sisters Abbey and Maggie Miller graduated from Gunston in 2022, they didn’t just share a last name—they famously shared the top academic honor as the class co-valedictorians, as well as National Merit Finalists.

Four years later, these standout alumnae have officially wrapped up their undergraduate careers, leaving an indelible mark on two world-class institutions. While their academic paths diverged into different engineering fields, their drive for innovation, leadership, and hands-on problem-solving remains exactly the same. Here is what Gunston’s top 2022 grads have been up to—and where they are headed next.

Abbey Miller ’22 graduated with high honors from Carnegie Mellon University with a bachelor's degree in mechanical engineering and a minor in business administration. “CMU was the perfect university for gaining hands-on engineering experience. I was the head mechanic of Fringe Racing for two years—building buggies, which are carbon fiber vehicles—as well as a mechanical tech lead for CMU’s first-year NASA Lunabotics team,” said Abbey.

Recently, Abbey and her teammates joined other student engineers from across the country at the Kennedy Space Center in Florida for the 2026 Lunabotics Challenge, demonstrating robotic technologies and systems engineering expertise designed to build and sustain long‑term lunar infrastructure. CMU’s team took home the Presentations and Demonstrations First Steps Awards. During her time at CMU, Abbey was also a member of Tau Beta Pi (the oldest engineering honor society in the United States, founded in 1885) and Pi Tau Sigma (a prestigious international honor society for mechanical engineers, founded in 1915). Additionally, she is an active member of the Society of Women Engineers.

Now, Abbey is headed to Stanford University to earn her master’s degree in aeronautics and astronautics. “I’m super excited to be heading to Stanford to pursue my goal of working with engines—whether plane, rocket, or jet—in the future!” said Abbey.

Maggie Miller ’22 graduated with high honors from the University of Pennsylvania, earning a degree in chemical and biomolecular engineering with a concentration in polymers and soft matter, alongside a minor in chemistry. During her time at Penn, Maggie kept busy both in and out of the lab. She served as the photo director for Penn Appétit food magazine, was a member of the Society of Women Engineers, and served on the planning committee for Zeta Tau Alpha. In an incredible display of entrepreneurship, Maggie also launched her own custom cake business while balancing her Ivy League coursework, incredibly fulfilling more than 100 orders in just two years.

“I have a passion for food science and commercial food production,” Maggie said. She put that precise passion to work on a commercial scale, completing a high-impact internship last summer with Ocean Spray Cranberries, where she got a firsthand look at major food manufacturing systems.

Next up for Maggie is a master’s degree in computational science and engineering at Georgia Tech.

Congratulations and good luck to the Millers!
