A physicist at the Jet Propulsion Laboratory, I have at various times worked on semiconductor surface and interface science, planetary science, MEMS (Micro Electro Mechanical Systems), and scientific instrument development. The highlight of my career at JPL was my service as project manager for the Mars Environmental Compatibility Assessment, a soil analysis payload intended to fly on the cancelled Mars Surveyor Program 2001 Lander. I was involved in the original conception of the Deep Space 2 probes that flew in 1999, and led a technology development team for the New Millennium Program that sponsored them. I have designed, built, and operated numerous laboratory instruments for materials analysis, a field in which I have published extensively. I was also the first recipient of JPL's Lew Allen Award for Excellence.
