Hi! I’m Stephan, a first-year PhD student in the Machine Learning Department at Carnegie Mellon University advised by Ameet Talwalkar. I am supported by the NSF GRFP. Previously, I did my undergrad at the University of Pennsylvania School of Engineering and Applied Sciences studying Computer Science and Mathematical Economics. I’m broadly interested in topics within machine learning and decision-making. At Penn I was fortunate to work with Kevin He and Aaron Roth on social learning, algorithmic fairness, and learning theory, as well as Yi Xing and Robert Wang at the Xing Lab on computational biology.

In my free time in undergrad I danced, choreographed, and filmed 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.
