[image-51]Dr. Jeffrey Sheehy serves as the Senior Technical Officer of the Space Technology Mission Directorate (STMD), advising the Associate Administrator and Deputy Associate Administrators on technology investment planning for the STMD portfolio. He has nearly 25 years of experience in aerospace technology research, development, and demonstration at NASA and the Air Force Research Laboratory (AFRL).
Before accepting his current appointment, he was chief engineer of the Technology Demonstration Missions program, which is managed by the NASA Marshall Space Flight Center. Sheehy provided technical and systems engineering oversight for a diverse portfolio of flight demonstrations including solar sail propulsion, supersonic decelerators, laser communications relay, deep-space atomic clock, cryogenic propellant storage, advanced chemical propellants, and telerobotics.
Prior to that, Sheehy was deputy chief engineer for the Orion Launch Abort System, which involved the development and demonstration of new solid rocket motor technologies including a reverse-flow abort motor and a pintle-modulated controllable-solid attitude control motor. The culmination of those efforts was a remarkably successful Pad Abort 1 flight test.
Earlier in his time at Marshall, Sheehy was a branch chief in the Propulsion Research Center, leading a team in the research and development of novel thruster concepts for high-power electric propulsion.
At AFRL, Sheehy was chief of the Propellants Branch, leading a group engaged in the development of new rocket propellants. Additionally, he was team lead of the High Energy Density Matter program, which pursued the discovery of highly energetic propellant ingredients.
Prior to moving to AFRL, Sheehy performed theoretical and computational chemical physics research on problems relevant to astrophysics, materials science, and space vehicle thermal protection at the NASA Ames Research Center.
Sheehy earned a PhD in chemical physics from Indiana University and received a prestigious postdoctoral associateship award from the National Research Council. He has authored or co-authored 40 journal articles in peer-reviewed scientific literature, as well as five book chapters and 30 technical reports. He has received numerous awards, including an Air Force Exemplary Civilian Service Award and a NASA Exceptional Service Medal.
