Zhen Lin

I was a Ph.D. student at the University of Illinois at Urbana-Champaign from 2020 to 2024, supervised by Professor Jimeng Sun. My research interest is in developing robust deep learning models for healthcare problems, with a focus on uncertainty quantification. I was fortunate to be recognized as a 2023 Meta PhD Fellowship Finalist.

Previously, I received my bachelor’s degrees in Computer Science, Mathematics, and Statistics from UChicago. I also spent two years at AQR Capital Management LLC as an alpha signal researcher.
