Mark J. W. Rodwell received the B.S. degree in electrical engineering from the University of Tennessee, Knoxville, in 1980, and the M.S. degree from Stanford University in 1982. He received the Ph.D. degree in electrical engineering from Stanford University in January 1988 and remained there as a research associate until September 1988. From 1981 through 1984 he worked for AT&T Bell Laboratories, developing optical transmission systems. He joined the Department of Electrical and Computer Engineering, University of California, Santa Barbara, in September 1988, where he is currently an associate professor. His research involves picosecond electrical shock-wave and soliton devices, millimeter-wave generation and instrumentation, picosecond photodetectors, fiber-optic transmission technologies, resonant tunneling diodes, and millimeter wave HBT and HEMT circuit design. Dr. Rodwell is the recipient of a 1989 National Science Foundation Presidential Young Investigator award.
