Biography

Ali Ramazani-Kebraya is currently an Associate Professor (with tenure) in CS at the University of Oslo. He was a postdoctoral fellow at LIONS. Before joining EPFL, he was a postdoctoral fellow at the Vector Institute in Canada. He works in machine learning and studies communication, optimization, privacy/security, and generalization aspects of machine learning algorithms. Ali received his Ph.D. from the University of Toronto. He is a recipient of the Natural Sciences and Engineering Research Council of Canada Postdoctoral Fellowship, which is equivalent to NSF fellowship in the US.
