Shuangjie Zhang | Texas A&M University

Welcome! I am currently a postdoctoral researcher associate at Texas A&M University working with Yang Ni and Bani K. Mallick. Before this, I received Ph.D. in Statistics at University of California Santa Cruz in 2024, supervised by Juhee Lee. Before joining UCSC, I completed my Master degree in Statistical Science at Duke University. I’m currently working on

Bayesian high-dimensional modeling
Causal Discovery
Bayesian nonparametric modeling
Application to biological data

MISC

My free time is mostly split among restful swimming, watching tennis (fan of Novak Djokovic), and playing chess. I played chess since I was 6, and obtained level of Candidate Master before 10. I regularly play chess online to have a mind ‘spa’. I also like traveling, and some great landscapes are here.
