I will be a Postdoc at Stanford University, with Jonathan Pritchard & James Zou. Previously, I obtained my Ph.D. in Biomedical Data Science at University of Wisconsin-Madison, advised by Qiongshi Lu and Lauren Schmitz. I got my undergraduate degree in Statistics from Nanjing University.
I am interested in the reliable use of AI/ML to accelerate genetic and scientific discovery, and in understanding the mechanisms and implications of treatment and genetic effect heterogeneity.
I develop theory, methods, and software for dissecting how genetic variation impact human complex traits and diseases, with a focus on accelerating drug discovery and advancing precision medicine.
Here are my selected papers, google scholar, and CV.
