Interview with Robert Jennings, retired since 2018 from the FDA’s Center for Devices and Radiological Health, where he was a research physicist. He recounts his childhood in Southern California and the formative influence of Sputnik on his physics education. Jennings discusses his undergraduate experience at Occidental and his master’s work at UCLA, and he describes his postgraduate work at the NASA Ames Research Center where he worked on optical detectors. He explains his decision to pursue a PhD at Dartmouth where he studied under John Merrill and worked on Tonks-Dattner resonances. Jennings describes the circumstances leading to his postdoctoral research in Brazil at the Institute of Atomic Energy, where he worked on medical radiation in the Division of Solid-State Physics. He discusses his subsequent research with John Cameron at the University of Wisconsin’s Medical Physics section to develop spectroscopy systems. Jennings explains that the expertise he developed in radiation and modeling in Wisconsin served as his entrée to the FDA ,which excited him as the place where the most impactful research was happening at the time. He surveys the major projects he was involved with over his career, including human visual signal detection, quality assessment of medical devices, improving mammography diagnostics, tomosynthesis, and CT scanners. At the end of the interview, Jennings surveys the fundamental developments that have advanced over the course of his forty-plus year career at FDA, his major contributions in tissue simulation science, and why he believes AI will become increasingly central to advances in medical imaging.
