Ari Feldman (Fed)

High-Speed Measurements Group Leader

Ari D. Feldman received his B.S. in Engineering Physics in 2006 and Ph.D. in Materials Science in 2012 from the Colorado school of Mines, Golden, CO, USA. His doctoral thesis involved the study of anomalous photoconductive decay measurements in silicon under high-optical-injection conditions. Continuing his research on photodetectors, in 2012 he joined the Sensors and Detectors Group as a post-doctoral researcher at the National Institute of Standards and Technology, Boulder, CO. In the Fall of 2013, he was awarded the National Research Council Post-Doctoral Fellowship and joined the High-Speed Measurements Group to develop high-speed photodetectors. As a staff researcher he has contributed to a variety of projects including the Gold Award winning LTE Impacts on GPS and Terahertz Synthesizer IMS. As of the spring of 2019, he is the Group Leader for the High-Speed Measurements Group.
