Andrew and Erna Viterbi Early Career Chair

Associate Professor, Departments of Electrical and Computer Engineering and Computer Science

University of Southern California

I'm currently a Ph.D. student in the Electrical Engineering department at Stanford, advised by Emmanuel Candes.

. Starting September I will spend one year at UC Berkeley EECS/Stats as a postdoctoral researcher. My sponsers Berkeley are Ben Recht.

and Martin Wainwright.

. In August 2015 I will join the USC EE department as an assitant professor. I'm interested in various problems that lie at the interplay between statistics, convex optimization, geometric functional analysis and theoretical computer science. I'm interested in using these tools for the design and analysis of algorithms for data mining, machine learning, computer vision and signal/image processing. Recently, I've also become interested in the analysis of non-convex problems via iterative methods and the interactions between convex optimization and algebraic geometry.
