Kai Chen
Kai Chen of Pierson College graduates with distinction with a degree in Art. A multi-disciplinary artist in painting, photography, and installation, their work presses against traditionally fixed images and addresses the alternative reality in which queer and non-binary artists may exist. Kai utilizes large-format film and pinhole cameras to build spirit-photography effects without digital manipulation. Their sustained intellectual engagement across disciplines served them as artist, thinker, and presence in their community. As co-head of Yale Visual Artists, Kai organized a large-scale open-call exhibition with rare administrative and curatorial skill. They also served on the faculty search committee for the Painting and Printmaking department. More than illustrative, Kai’s practice investigates with intentionality and rigor.

The Josiah Willard Gibbs Prize
The Josiah Willard Gibbs Prize is awarded to a graduating senior for excellence in engineering and the applied sciences.
Shaun Pexton
Shaun Pexton of Silliman College graduates cum laude, with distinction in both his majors: Applied Physics and Computer Science. He is the winner of the Yale Science and Engineering Association Award for Outstanding Undergraduate Achievement. His coursework reaches deep into graduate territory not to accumulate credits but to fuel research that has already reshaped corners of the field. That research has produced results that would distinguish a doctoral student. At Quantum Motion Technologies in Oxford, Pexton co-authored “Snakes on a Plane: Mobile, Low-Dimensional Logical Qubits on a 2D Surface,” now under review and accompanied by a pending patent. With his Yale advisors Aleksander Kubica and Yongshan Ding, he produced a second manuscript on error mitigation within fault-tolerant quantum circuits, submitted to MICRO-59. At ASML Research, the only non-PhD member of the R&D team, he built machine-learning schemes for ultrafast optical metrology. He won MIT’s iQuHack and twice won the Johns Hopkins × OpenAI AI Hackathon. Pexton is not only a scholar but a community builder. As board member at Code Haven, he manages volunteers teaching computer science to over two hundred students across New Haven public schools, and teaches a classroom himself each week. He sits on both the Yale Physics and Engineering advisory committees, co-presides over Yale Undergraduate Quantum Computing, plays the saxophone in the Yale Jazz Collective, and this year served as a First-Year Counselor. He has also swum the English Channel, raising over $10,000 for charity. For his scholarship, his research, and his service to Yale and New Haven, Yale College is proud to award the Josiah Willard Gibbs Prize to Shaun Pexton.

The Alpheus Henry Snow Prize
The Alpheus Henry Snow Prize is awarded to that “senior who through the combination of intellectual achievement, character, and personality, shall be adjudged by the faculty to have done the most for Yale by inspiring in his or her classmates an admiration and love for the best traditions of high scholarship.”
August Rios
August Rios, of Timothy Dwight College, graduates magna cum laude, with distinction, in Intensive Sociology. A Rhodes Scholar, he will pursue graduate study in Comparative Social Theory at Oxford next year. August’s work exemplifies a rare integration of intellectual rigor and moral commitment. His senior thesis, “If Walls Could Talk: Chronic Disrepair, Habitability Policy, and the Low-Income Renter Experience in New Haven,” brings together theoretical insight, statistical analysis, and deeply engaged fieldwork. Working with Yale’s Housing and Health Equity Lab and as a mayoral appointee to the city’s Affordable Housing Commission, he conducted a meticulous study of housing code violations and enforcement. Yet his work did not remain at the level of data alone: August went door to door, documenting living conditions and listening with care to the experiences of New Haven residents, producing an ethnography marked by patience, respect, and clarity of purpose. This integration of scholarship and action has defined August’s time at Yale. As a first-year student, he founded Connecticut’s only volunteer small claims assistance organization to support tenants seeking redress in court. As a sophomore, he became a licensed real estate agent in order to represent low-income first-time homebuyers at no cost. For August, the questions of policy and justice are not abstractions but lived commitments—what one professor rightly described as a calling. For his exceptional scholarship, his integrity of purpose, and his profound commitment to the communities he serves, Yale College takes great pleasure in bestowing the Alpheus Henry Snow Prize upon August Rios.
