I am a Postdoc in the statisitics department of Wharton school at the University of Pennsylvania, working with Prof. Tony Cai. Previously, I received my Ph.D in the mathematics department at Stanford University, where I worked with my Ph. D advisor Prof. Emmanuel Candes.
I am interested in the roles of sparse and low-rank structures in high-dimensional statistics, unsupervised learning and signal processing. In particular, I am interested in compressed sensing, robust PCA, community detection in graphical models, phase retrieval, and testing with sparse alternatives. Here is my google citation page.
