Professor Holt received his PhD in physics from Stony Brook University in 2008 under the supervision of Gerald E. Brown. Before joining the Physics and Astronomy department at Texas A&M in 2015, he performed postdoctoral research at the Technical University of Munich and the University of Washington in Seattle. His research explores the structure, phases, and dynamics of strongly interacting matter (protons, neutrons, quarks, and gluons) at high temperatures. The long-term goal is to understand how the strong nuclear force shapes the structure, evolution, and observable emissions of high-energy astrophysical systems, such as core-collapse supernovae, neutron stars, and binary neutron star mergers. Professor Holt works to develop microscopic models of hot and dense neutron-rich matter based on the low-energy effective field theory of strong interactions. The nuclear thermodynamic equation of state, governing neutron star structure as well as the hydrodynamic evolution of supernovae and neutron star mergers, is being investigated across the range of extreme astrophysical conditions needed for accurate numerical simulations. This will enable more reliable predictions for the electromagnetic, neutrino, and gravitational wave signals from supernovae and neutron star mergers. To help pin down the astrophysical site for the formation of r-process elements, such as gold and uranium, Professor Holt studies nucleon spectral properties and response functions of hot nuclear matter. Finally, Professor Holt is involved in new efforts to exploit high-performance computing to simulate with quantum Monte Carlo methods dilute neutron matter at finite temperature in order to better understand the effect of neutron superfluidity on transport and cooling phenomena in proto-neutron stars.
