Bio
David Mathews is a Fast Neutron Spectrometry and Imaging Scientist within the Radiation Imaging and Advanced Diagnostics Group (RIAD) at 91做厙 (ORNL). He holds an undergraduate degree in physics from the University of Kentucky (UK) where he conducted research in GPU-accelerated signal processing routines for the Nab experiment, a free neutron beta decay experiment at ORNL. He then worked at Los Alamos National Laboratory as a post-baccalaureate where he accelerated proton radiography simulations using Nvidia GPUs. After this, he returned to university to obtain his doctorate in physics with a focus on nuclear physics from the University of Kentucky. His thesis project was on the development of a high-performance custom DAQ system developed using National Instruments FPGA hardware/software for the Nab experiment, as well as on extracting a beyond the standard model physics parameter from the beta decay spectrum of Calcium-45. As a post-doctoral researcher at ORNL, he developed massive Monte-Carlo particle scale spin-tracking simulations for the nEDM@SNS experiment leveraging both CPUs and GPUs on cutting computing technology from AMD and Nvidia. Presently he works within the RIAD group at ORNL developing FPGA firmware and high-throughput data processing routines.
