Jack Deslippe

Jack Deslippe is a Researcher at Lawrence Berkeley National Laboratory (LBNL), specifically within the National Energy Research Scientific Computing Center (NERSC). He currently serves as the acting lead of the Applications Performance Group (APG), where he optimizes scientific application codes for NERSC's high-performance computing systems including the Cori supercomputer. He leads the NERSC Exascale Science Application Program (NESAP) and represents key projects like BerkeleyGW, Quantum ESPRESSO, and PARSEC.

His educational background includes:

• Ph.D. in Physics, University of California, Berkeley, 2011

Dr. Deslippe specializes in computational materials science and chemistry, focusing on scaling many-body Green's function methods for excited-state properties of complex materials. As a lead developer of the BerkeleyGW software package and architect of its 1.0 release, he combines expertise in high-performance computing, quantum mechanics simulations, and scientific software infrastructure. His work extends to web-based science gateways including MyNERSC and the ALS "SPOT" portal.
