Personal Information

I'm an assistant professor in Department of Statistics at the Wharton School, the University of Pennsylvania. Before joining Wharton, I was a William H. Kruskal Instructor in Department of Statistics at the University of Chicago. I obtained my PhD degree from Department of Statistics and Data Science at Yale University, advised by Professor Harrison Zhou. I have a broad interest in the theory and application of statistics and machine learning. My current research interests include:


STAT 431: Statistical Inference (Fall 2019)
STAT 24500: Statistical Theory and Method 2 (Spring 2019, University of Chicago)
STAT 22000: Statistical Methods and Applications (Fall 2018, University of Chicago)
