I earned my PhD in Statistics in 2014 from the Department of Statistics at Texas A&M University, after which I spent two years as a post-doc at the University of Mannheim before starting as an assistant professor at USC in 2016. My research has focused on the bootstrap, nonparameteric estimation, high dimensional regression, and post-selection inference problems.
