Hi! I’m Stephan, a final-year BSE student in the University of Pennsylvania School of Engineering and Applied Sciences studying Computer Science and Mathematical Economics. I’m interested in topics within machine learning, game theory, and economics. I am fortunate to work with Kevin He and Aaron Roth on social learning, algorithmic fairness, and learning theory. Previously, I was fortunate to work as a research assistant at the Xing Lab, where I worked with Yi Xing and Robert Wang.

In my free time I dance, choreograph, and film for Pan-Asian Dance Troupe, and I am a long-time wushu student and enthusiast. I also compose and play instrumental music (formerly with Penn Chamber), primarily for the piano.
