Biography

Dr. Erik Draeger is the group leader of the Scientific Computing Group in the Center for Applied Scientific Computing. He is also the Director of the High Performance Computing Innovation Center (HPCIC) and the RADIUSS project at LLNL.  Previously, Dr. Draeger was the Deputy Director for Application Development for the DOE Exascale Computing Project and before that the developer of the LLNL qball branch of the open source Qbox code, a massively parallel first-principles molecular dynamics code originally written by Francois Gygi. Dr. Gygi and Dr. Draeger won the 2006 Gordon Bell award for sustained floating point performance on the Blue Gene/L supercomputer. He co-developed the Cardioid cardiac electrophysiology code, a highly scalable biology application used to model arrhythmias in human heart geometries at near-real time, and is one of the main developers of the HARVEY code, a Lattice Boltzmann fluid dynamics code used for circulatory modeling that was a 2015 Gordon Bell Award Finalist.

Dr. Draeger earned a Bachelor's degree in Physics from the University of California, Berkeley in 1995 and later earned a Master's and a Ph.D. in theoretical condensed matter physics from the University of Illinois, Urbana-Champaign in 2001, working with Professor David Ceperley on path integral Monte Carlo simulations of superfluid helium droplets and surfaces.
