(My last name is pronounced "Ven-cut-rum-uh-nun")


I am Professor of Information Engineering at the University of Cambridge, and a Staff Fellow at Trinity Hall. I am part of the Signal Processing and Communications Lab in the Division of Information Engineering.

I received my PhD in Electrical Engineering from the University of Michigan, Ann Arbor in 2008, and my undergraduate degree from the Indian Institute of Technology, Madras in 2002. Before joining the University of Cambridge in 2013, I held post-doctoral positions at Stanford University and Yale University. I am an Associate Editor of the IEEE Transactions on Information Theory, and from 2018-21 was a Fellow at the Alan Turing Institute, and an Associate Editor of the IEEE Transactions on Communications.


My research interests are broadly in statistical learning, information theory, and communications.
