Arthur is the Lead for Strategic Development for the Inertial Confinement (ICF) Program at Lawrence Livermore National Laboratory (LLNL) and the Associate Director for Strategy of the Livermore Institute for Fusion Technology (LIFT). Arthur is focused on further developing inertial fusion for economic, energy, and national security. Since joining the National Ignition Campaign at LLNL in 2011, Arthur has held a number of positions within the ICF program, including leading experimental campaigns and analysis working groups that achieved fusion ignition in 2022. His research has focused on using experimental measurements, together with analytic models and detailed simulations to understand and mitigate the principal mechanisms that inhibited fusion ignition. Arthur received his Bachelor degree from the University of California, Davis in Optical Science Engineering, and his Ph.D from the University of California, Los Angeles in Plasma Physics.
