About me

I am a Ph.D. student majoring in Social and Engineering Systems at MIT IDSS and CSAIL. I have been fortunately working with Prof. Marzyeh Ghassemi on Machine Learning for Healthcare.

Previously, I received my M.S. in Machine Learning at CMU where I was advised by Prof. Eric P. Xing and Prof. Louis-Philippe Morency. I received my B.S. in Computer Science, Statistics, and Mathematics at UIUC where I was advised by Prof. Jiawei Han and Prof. Hari Sundaram.

Here are some highlights of my experience. Please refer to my CV for more details.
