Tim has a PhD in Electrical Engineering from the University of Delaware. He worked for five years in private industry before joining the National Institute of Standards and Technology (NIST) in 1999. At NIST he published research in internet telephony, self-organizing wireless networks, and spectrum sharing, including dynamic spectrum access. He was also a program manager in NIST’s Advanced Technology Program (ATP).
