I am an Assistant Professor in the Department of Statistics at Columbia University. I am also a member of the Data Science Institute. Prior to joining Columbia in 2021, I spent a year as a postdoc at Duke University, mentored by David B. Dunson. In 2020 I received a Ph.D. in Statistics from the University of Michigan, advised by Gongjun Xu. In 2015 I received a B.S. in Mathematics from Tsinghua University.
I am generally interested in latent variable models, statistical machine learning, high-dimensional statistics, and psychometrics. My specific research interests include the methods, theory, and applications of graphical models with latent variables, multivariate categorical data, mixture models, tensor decompositions, deep generative models, and cognitive diagnostic modeling.
