Hello! I am a second-year PhD student in the UPenn Theory Group, where I am incredibly fortunate to be advised by Erik Waingarten and Sanjeev Khanna. My research interests lie in algorithm design and complexity for problems in high dimensional geometry, graph theory, and machine learning. Previously, I studied computer science and math at Columbia, where I was fortunate to be mentored by Alexandr Andoni and Xi Chen.
