Expertise
coding, communications, information theory, graphical models, methods of statistical physics applied to problems in communications and computer science, codes for quantum, foundations of machine learning
Mission
Design and analysis of error-correcting codes for both classical and quantum communication, as well as the theoretical foundations of modern machine learning.
Ruediger L. Urbanke received his Dipl. Ing. degree from the Vienna University of Technology, Austria, in 1990, followed by an M.Sc. and a Ph.D. in Electrical Engineering from Washington University in St. Louis, MO, in 1992 and 1995, respectively. From 1995 to 1999, he served in the Mathematics of Communications Department at Bell Labs, after which he joined the School of Computer & Communication Sciences (I&C) at EPFL, where he is part of the Information Processing Group.
He was an Associate Editor of the IEEE Transactions on Information Theory from 2000 to 2004, served as President of the IEEE Information Theory Society in 2017, and is currently the Dean of I&C. Dr. Urbanke is co-author of Modern Coding Theory (Cambridge University Press).
His research spans the design and analysis of error-correcting codes for both classical and quantum communication, as well as the theoretical foundations of modern machine learning.
