Sohom Bhattacharya

I am an Assistant Professor in Department of Statistics, University of Florida. I am broadly interested in high-dimensional statistics and statistical machine learning, focusing on learning under data heterogeneity and complex dependence. Recently, I received 2027 Honorable Mention, Bernoulli Society New Researcher Award. I serve as an Associate Editor for Sankhya A.

Previously, I was a postdoc in Princeton ORFE mentored by Professor Jianqing Fan. I completed my PhD from Department of Statistics, Stanford University, supervised by Professor Sourav Chatterjee.
