David A Gwaltney received his undergraduate and master's degrees in Electrical Engineering from Auburn University, in Auburn, Alabama. He has 15 years of experience designing embedded controllers for NASA and has published several papers on control applications. Mr. Gwaltney is the Lead Design Engineer for Propulsion High Impact Avionics Technology (PHIAT ) project developing hardware and software for the proof-of-concept demonstration of a distributed, fault-tolerant network of sensors and actuators. Originally targeted for rocket engine control and monitoring, the project scope has expanded to be relevant to other space vehicle subsystems as well. Mr. Gwaltney is also the Principal Investigator for FY05/FY07 Intelligent Systems NRA task entitled "Evolvable Hardware for Realization of a Robust Fault-tolerant Analog Controller." He has been the Principal Investigator for several Marshall Space Flight Center Director Discretionary Fund tasks covering topics on adaptive control, fault detection and isolation in actuators and evolvable hardware. He has experience in flight hardware design for future International Space Station life support systems and microgravity experiments to include experience in the design and implementation of digital circuits in Field Programmable Gate Arrays (FPGAs). He worked at NASA's Langely Research Center from July 1990 to August 1998, where he worked on control system design for wind tunnels and other test facilities. Mr. Gwaltney is currently the Lead of the Embedded Control Design Team at NASA's Marshall Space Flight Center in Huntsville, Alabama.
