Francisco Ponce is currently a physicist at Pacific Northwest National Laboratory in the National Security Directorate, developing capabilities related to internal quantum information sciences as part of Pacific Northwest National Laboratory’s involvement in the Co-design Center for Quantum Advantage (C2QA). His current research areas include the characterization of loss mechanisms in superconducting transmon devices and the use of superconducting sensors as high-resolution photon/particle detectors. He is working collaboratively on the Beryllium Electron capture in Superconducting Tunnel junctions (BeEST) experiment to search for sterile neutrinos by establishing a process to enable phase IV of the experiment. This effort involves scaling up the number of sensors, transitioning to a dilution refrigerator, and integrating room-temperature detectors to enhance the reach of the experiment. He previously worked on the SuperCDMS experiment to search for dark matter and studied the nuclear decay of 229mTh as a potential resonator in a nuclear clock. Dr. Ponce obtained his doctorate from the University of California, Davis, his master’s degree from San Francisco State University, and his bachelor’s degree from the University of California, Berkeley.
