I am a final-year PhD student in CS @ UIUC. I am fortunate to be advised by Prof. Jimeng Sun. I also closely work with Prof. M. Brandon Westover from Harvard Medical School and Beth Israel Deaconess Medical Center. Previously, I worked with Dr. Cao (Danica) Xiao from GE Healthcare, Prof. Tarek Abdelzaher, Prof. Hari Sundaram, Prof. Xiaofeng Gao, and Prof. Gongshen Liu. I finished B.S. in Shanghai Jiao Tong University in 2019.

I am building machine learning models and systems for healthcare time-dependent data (e.g., biosignals, EHRs). Relevant techniques are (not limited to) tensor decomposition, timeseries and sequence modeling, self-supervised learning, domain generalization.

We are building [PyHealth], a deep learning toolkit for healthcare AI research and its reproducibility (19k+ downloads!). Check out the [GitHub] and [Live Records].
