About Me
I’m a fourth year Ph.D. student in the Program in Applied and Computational Mathematics at Princeton University and I am fortunate to be advised by Prof. Jason Lee. I’m currently working on understanding implicit regularization and feature learning in deep learning and my research interests broadly lie in optimization and machine learning. My research is supported by a National Science Foundation Graduate Research Fellowship and a Jane Street Graduate Research Fellowship.
I did my undergrad at Duke University where I received a B.S. in Mathematics and was fortunate to work with Prof. Cynthia Rudin and Prof. Hau-Tieng Wu.
