Dr Jim Gaffney is a physicist and group leader at Lawrence Livermore National Laboratory (LLNL). He received his Master’s degree in Theoretical Physics from the University of Durham in the UK in 2006, a PhD in Plasma Physics from Imperial College London in 2011, and joined LLNL’s physics division as a postdoc and then staff scientist. In 2020, Jim moved to LLNL’s Center for Applied Scientific Computing where he leads the Uncertainty Quantification and Optimization group. Jim is interested in the intersection of data science, large-scale simulation, and experiments in inertial confinement fusion (ICF), high energy density physics, and beyond. He has helped develop new `cognitive simulation’ approaches to the design and interpretation of ICF experiments and leads projects applying machine learning and statistical methods to a range of scientific problems. He currently co-leads an effort to integrate deep surrogates into expensive multiphysics simulations, and is focus area lead in the Materials Science in Extreme Environments (MSEE) university research alliance.
