Tom Hou is Bradley Distinguished Professor of Electrical and Computer Engineering at Virginia Tech, Blacksburg, VA. He received his B.E. degree from the City College of New York in 1991, M.S. degree from Columbia University in 1993, and Ph.D. degree from New York University (NYU) Tandon School of Engineering in 1998, all in Electrical Engineering. From 1997 to 2002, he was a Researcher at Fujitsu Laboratories of America, Sunnyvale, CA. Prof. Hou's research interests are to develop innovative solutions to complex cross-layer optimization problems in wireless networks. He is particularly interested in exploring new performance limits at the network layer by exploiting advances at the physical layer. In recent years, he has been actively working on cross-layer optimization problems for cognitive radio wireless networks, cooperative communications, MIMO-based ad hoc networks and energy related problems. Prof. Hou was a recipient of an ONR Young Investigator Award (2003) and an NSF CAREER Award (2004). He has published extensively in IEEE and ACM transactions/journals and top-tier IEEE/ACM conferences. He received five best paper awards from IEEE (including IEEE INFOCOM 2008 Best Paper Award and IEEE ICNP 2002 Best Paper Award) and two Best Paper Awards from the ACM. Prof. Hou was named an IEEE Fellow for contributions to modeling and optimization of wireless networks.
