Jean-Luc Vay is a Senior Physicist at Lawrence Berkeley National Laboratory (LBNL) and the coordinator of modeling and simulation activities for LBNL’s Applied Physics and Accelerator Technologies Division. His research interests center on advanced modeling of particle accelerator physics and technology, especially for the development of novel accelerators, including high-energy physics colliders, laser plasma accelerators, light sources, and drivers for high energy density physics and heavy ion inertial fusion. A significant portion of his research involves the development of novel algorithms, their implementation in production codes and optimization on a multiplicity of platforms (from PC to supercomputers), the validation of these algorithms, and the application of the codes to the solution of practical accelerator physics problems. This work, and allied efforts of others at LBNL, are brought together as the Berkeley Lab Accelerator Simulation Toolkit (BLAST). Vay He is recipient of the 2013 US Particle Accelerator School Prize for Achievement in Accelerator Physics and Technology for original contributions to the development of novel methods for simulating particle beams, particularly the Lorentz boosted frame techniques, and for the successful application of these methods to multi-scale, multi-species problems. He also received the 2014 NERSC Award for Innovative Use of High Performance Computers for his work on “boosted frame” and novel spectral decomposition techniques.
