Interests: I am broadly interested in the theoretical and algorithmic aspects of mathematical statistics, information theory, and machine learning. My research is driven by application domains such as power systems and wireless communication networks.

​

Short bio: I received the B.Sc. (2002) and M.Sc. (2004) degrees in Electrical Engineering from Sharif University of Technology, and the M.A. degree in Statistics and the Ph.D. degree (2010) in Electrical Engineering from Columbia University. I was a postdoctoral research associate at Princeton University from 2010 to 2012. 

​

I am currently an Associate Editor for the IEEE Transactions on Information Theory. In the past, I have served as an Associate Editor for the IEEE Transactions on Signal Processing, an Associate Editor for the IEEE Transactions on Communications, an Editor for the IEEE Transactions on Smart Grids, a Guest Editor for the IEEE Signal Processing Magazine, and a Guest Editor-in-Chief for the IEEE Transactions on Smart Grid. I received an NSF CAREER Award in 2016, the Jury Award for Excellence in Research in 2011 from Columbia University, and the James M . Tien '66 Early Career Award from Rensselaer.
