Dr. Myers is the program manager for Geophysical Monitoring Programs.
Dr. Myers's research focuses on nuclear explosion monitoring with emphasis on technologies that improve the accuracy of event locations and characterization of uncertainty. Dr. Myers led development of the BayesLoc method for simultaneous relocation of many seismic events and assessment of data quality. He also leads the multi-national-laboratory Regional Seismic Travel Time (RSTT) effort which accounts for the effects of Earth heterogeneity in a method that is computationally efficient enough for use in real-time operational systems. Machine learning is currently being explored as a new way to achieve higher prediction fidelity in a computationally efficient algorithm. In additional to these contributions to nuclear non-proliferation, Dr. Myers maintains an interest in basic Earth science, particularly regional and whole-Earth structure.
