His research activities center on spacecraft and optical instrument control systems for spacecraft. He is currently investigating jitter stabilization methods for optical sensors, lidar control systems modeling, and magnetic attitude control techniques. He previously designed the attitude determination and control system for SDL's Skipper spacecraft, as well as participating in other programs and studies on small spacecraft control problems for BMDO, MDA, DARPA, ONR, and AFRL. Dr. Fullmer has worked in spacecraft control system design since 1993.
