Biography
Terry Todd received the B.A.Sc, M.A.Sc and Ph.D degrees in Electrical Engineering from the University of Waterloo in Waterloo, Ontario, Canada. Dr. Todd is currently a Professor of Electrical and Computer Engineering at McMaster University in Hamilton, Ontario, Canada. In 1991 Dr. Todd was on research leave in the Distributed Systems Research Department at AT&T Bell Laboratories in Murray Hill, NJ. He also spent 1998 as a visiting researcher at The Olivetti and Oracle Research Laboratory (ORL) in Cambridge, England.During 2005/2006, Dr. Todd was on research leave at Research In Motion Inc., where he worked on vertical handover for multi-mode cellular handsets.

At McMaster he has been the Principal Investigator on a number of research projects in the optical and wireless networking areas. He currently directs a group working on wireless mesh networks and wireless VoIP. Professor Todd formerly held the NSERC/RIM/CITO research chair on wireless networks. He is a past Associate Editor of the IEEE/ACM Transactions on Networking and the IEEE Transactions on Mobile Computing.

Professor Todd is a Professional Engineer in the province of Ontario.
