Our Leading Team

Key Personnel


Founder, President & CEO

Brian received his PhD in physics from UCLA in 1982. He has over 30 years of sensor experience spanning spaceborne and airborne radar simulation, radar image algorithm development, radar low observables, radar measurements, simulation of IR sensor systems, multiple hypothesis trackers, and radar automated target recognition systems. In the early 90s he was a co-developer of a system for making diagnostic airborne radar images of the B-2 bomber. The program was highly successful and was described by the then Secretary of the Air Force as a “national treasure." As head of EMSI, Brian has led the development of the company into the areas of ISAR image processing and radar automated target recognition.


Senior Scientist

Stephen is a recognized subject matter expert in radar, and as such he functions as EMSI’s technical innovator. He has 35 years of experience developing and automating radar signal and image processing technology for target detection, identification, tracking and engagement and for measurement of target motion dynamics. He received his PhD in physics from Stanford University. Stephen is the co-author of two books on radar signal processing, one software package, numerous papers and has taught courses on radar in the U.S., Europe and Asia.
