Anders Petersson is a computational mathematician in the Center for Applied Scientific Computing @ LLNL, where he currently leads projects on Quantum optimal control and characterization. Anders' research lies at the cross-section of numerical methods for wave propagation, high performance computing, optimization and optimal control. His research is performed in close collaboration with physicists specializing in quantum information sciences. Anders previously lead the development of the exa-scale computing code SW4 for large scale seismic wave propagation, under the Serpentine Wave Propagation Project.
