## About me

I am an Assistant Professor at the ECE Department at UW Madison. I am a fellow at the Grainger Institute for Engineering and an affiliate with the optimization group at the Wisconsin Institutes for Discovery. My research interests lie in the areas of information theory, network science, probability and statistics.

From 08/15 - 08/16, I was a postdoctoral fellow at the Warren Center for Network and Data Sciences at the University of Pennsylvania. I was hosted jointly by the Statistics and the CIS departments. I completed my PhD in the EECS Department at UC Berkeley in 08/15, where I was advised by Professor Venkat Anantharam. I worked on problems in information theory with a focus on the connections between convex geometry and information theory. My thesis may be found here: Thesis.

Prior to Berkeley, I graduated with a Bachelor of Technology (B. Tech) degree in Electrical Engineering from IIT Bombay in 08/10. I was advised by Professor Abhay Karandikar and Professor Sibi Raj B Pillai. I also spent three exciting months (05/09-07/09) at the Department of Information Engineering, Chinese University of Hongkong working with Professor Chandra Nair.
