Background

I am currently an assistant professor in the Department of Statistics at the University of Wisconsin-Madison. From 2015 to 2016, I did my postdoc in Economics at the Stanford Graduate School of Business, advised by Guido Imbens. In 2015, I received my Ph.D. in Statistics at the Wharton School of Business of the University of Pennsylvania and I was co-advised by T. Tony Cai and Dylan S. Small.

Broadly speaking, my research is focused on developing theory and methods to analyze causal relationships in large observational data by leveraging instrumental variables, econometrics, high dimensional inference, and causal inference. I am interested in applications to genetics, epidemiology, health policy research, and economics.

I am currently an associate editor for Biometrics.
