Biography

Ahmad Beirami received the B.Sc. degree in electrical engineering from Sharif University of Technology, Tehran, Iran, in 2007 and the M.Sc. and Ph.D. degrees in electrical and computer engineering from the Georgia Institute of Technology, Atlanta, GA, USA, in 2011 and 2014, respectively. He is currently a postdoctoral fellow with the school of engineering and applied sciences at Harvard University, and also with electrical engineering and computer science department at MIT. Previously, he was a postdoctoral associate at Duke University. His research interests broadly include information theory, statistics, machine learning, and networks. He is the recipient of the 2013-2014 School of ECE Graduate Research Excellence Award and the 2015 Sigma Xi Best Ph.D. Thesis Award from the Georgia Institute of Technology.
