Sumit Roy

  • Integrated Systems Professor

Sumit Roy has been a faculty member in Electrical & Computer Engineering at the University of Washington since 1998, where he is presently Integrated Systems Professor. He spent 2001-03 on academic leave at Intel Wireless Technology Lab as a Senior Researcher engaged in systems architecture and standards development for ultra-wideband systems (Wireless PANs) and next generation high-speed wireless LANs. During January-July 2008, he was the Science Foundation of Ireland’s E.T.S. Walton Awardee for a sabbatical at University College, Dublin, and during summer 2011 he was the recipient of a Royal Academy of Engineering (UK) Distinguished Visiting Fellowship

Roy’s activities for the IEEE Communications Society (ComSoc) include membership of several technical and conference program committees, notably the Technical Committee on Cognitive Networks. He has served as Associate Editor for all the major ComSoc publications in his area at various times, including the IEEE Transactions on Communications and IEEE Transactions on Wireless Communications, and as a Distinguished Lecturer (2014-15) for ComSoc. He was elevated to IEEE Fellow by ComSoc in 2007 for “contributions to multi-user communications theory and cross-layer design of wireless networking standards.”

Research Interests

Wireless communications/networking; emerging applications (smart grid, vehicular networks, cognitive and sensor networks).
