David Sohl has 35 years experience in the development, testing, and operation of space flight instruments and instrument electronics. This experience includes all aspects of instrument and electronics development, fabrication, assembly, and test. He has worked as a technician, design engineer, test engineer, lead engineer, chief engineer, integration and test manager, and instrument manager. He worked on multiple types of instruments in all wavelength ranges (UV, IR, Visible, X-ray, Gama Ray) that operate from 30°C down to 0.25°K. These instruments have flown on all platforms (aircraft, balloons, sounding rockets, space shuttle, and satellites). He has also worked on all phases of project lifecycle from proposal through development and on-orbit operation. He recently supervised the development of the JWST NearSpec instrument electronics, SMAP radiometer electronics and science data processing system development, and the development of two instrument electronics boxes for the ASTRO-H mission. He is currently serving as the Branch Head of the Instrument Electronics Development Branch at the Goddard Space Flight Center. He graduated from Johns Hopkins University with a degree in Electrical Engineering.
