Dr. Simpson earned B.S., M.S., and Ph.D. degrees in Electrical Engineering from the University of Tennessee in 1983, 1987, and 1991, respectively. His dissertation research focused on charge trapping correction in high-purity germanium radiation detectors. At the time he received his Ph.D. Simpson worked in R&D at EG&G Ortec, and moved to the Scientific Staff of the Oak Ridge National Laboratory in 1992 where he initially worked on the design of high-speed, custom, analog, integrated circuits for collider physics experiments. Later Simpson’s research interest focused more on nanoscale structures, and in particular, on the interface between nanoscale devices and biological systems. Simpson is now a Distinguished Research Staff Member and Theme Leader in the ORNL Center for Nanophase Materials Sciences. Dr. Simpson began a joint faculty appointment with the University of Tennessee in 1993, first with the Electrical and Computer Engineering Department, and now with the Materials Science and Engineering Department, where he teaches nanobiosciences courses and performs research at the physical-biological sciences boundary. Dr Simpson has authored or co-authored 115 peer reviewed journal papers, holds 24 U.S. Patents, and has presented numerous invited talks at conferences, workshops, and symposia.
