Bronson Messer is a Distinguished Scientist and Director of Science at the Oak Ridge Leadership Computing Facility (OLCF) at ORNL. He is also a Joint Faculty Associate Professor in the Department of Physics & Astronomy at the University of Tennessee. His primary research interests are related to the explosion mechanisms and phenomenology of supernovae (both thermonuclear and core-collapse), especially neutrino transport and signatures, dense matter physics, and the details of turbulent nuclear combustion

Dr. Messer is a member of the American Astronomical Society and he currently serves on the American Physical Society’s Committee on Informing the Public (2018).
