Biography:

Thomas Hou obtained his B.E. degree from the City College of New York in 1991, the M.S. degree from Columbia University in 1993, and the Ph.D. degree from Polytechnic University, Brooklyn, New York, in 1998, all in Electrical Engineering. From 1997 to 2002, He was a researcher at Fujitsu Laboratories of America, IP Networking Research Department, Sunnyvale, California. Since Fall 2002, he has been an Assistant Professor at Virginia Tech, the Bradley Department of Electrical and Computer Engineering, Blacksburg, Virginia.

His current research interests include resource (spectrum) management and networking issues for SDR-enabled wireless networks, optimization and algorithm design for wireless ad hoc and sensor networks, and video communications over dynamic ad hoc networks. In recent past, he also had work on scalable architectures, protocols, and implementations for differentiated services Internet, service overlay networking, video streaming, and network bandwidth allocation policies and distributed flow control algorithms. He has published over 100 journal and conference papers in the above areas and is a recipient of the 2004 IEEE Communications Society Multimedia Communications Best Paper Award, the 2002 IEEE International Conference on Network Protocols (ICNP) Best Paper Award, and the 2001 IEEE Transactions on Circuits and Systems for Video Technology (CSVT) Best Paper Award. He is a member of ACM and a senior member of IEEE.
