Hi, I am a fifth year Ph.D. candidate in Biomedical Data Science at University of Wisconsin-Madison, advised by Prof. Qiongshi Lu and Lauren Schmitz. Previously, I got my undergraduate degree in Statistics from Nanjing University.
I am interested in how to make reliable genetic and scientific discoveries from machine learning predictions, and in understanding the mechanisms and implications of context-dependent genetic effects.I develop theory, statistical methods, and software for analyzing genetic data, with a focus on accelerating drug discovery and advancing precision medicine.
Here are my selected papers, google scholar, and CV.
