About me

Welcome to my personal website! I am currently a Ph.D. student in the Department of Electrical and Computer Engineering at the University of Maryland (UMD). I have had the privilege of working in the CASE Lab under the guidance of Professor Ang Li. My research interests include Federated Learning, Large Language Models, and AI for medicine.
