Yichi Zhang

Welcome!

I am an assistant professor in Department of Statistics at Indiana University Bloomingtom.

Before that I was a Postdoctoral Scholar in the Department of Biostatistics & Bioinformatics and the Fuqua School of Business at Duke University, advised by Alexandre Belloni and Ethan X. Fang. I received my Ph.D. in Statistics from North Carolina State University (NCSU) in 2023, advised by Minh Tang and Shu Yang. During my doctoral studies, I was also advised by Dehan Kong and Weining Shen on multiple research projects. I received a B.S. in Mathematics and Applied Mathematics from Sichuan University in 2018 .
