I am an AI researcher and PhD candidate in Electrical and Computer Engineering at Harvard University, based at Massachusetts General Hospital, where I work with Prof. Na Li and Prof. Quanzheng Li.
Before Harvard, I received BS and MS degrees in Electrical and Computer Engineering from Carnegie Mellon University, and worked as a software engineer at Google, Meta, Duolingo, and JP Morgan Chase.
