About Me

I am an Assistant Professor in the School of Electrical, Computer, and Energy Engineering at the Arizona State University. Before this I was a Postdoctoral Fellow in the Electrical and Computer Engineering department at Rice University where I worked with Rich Baraniuk. And prior to that, I was at the Machine Learning Department at Carnegie Mellon University where I worked with Aarti Singh.
I received my M.S. and Ph.D. in Electrical Engineering in 2010 and 2014 respectively from the University of Wisconsin - Madison, where I was advised by Rob Nowak and Stark Draper. Before that, I received my B. Tech in Electronics and Communication Engineering in 2008 from VIT University.
My research interests span topics in Machine Learning, Statistics, Signal Processing, Networked Systems, and Information Theory. More on my research can be found here.
