Biographical Sketch

Jack Deslippe specializes in the support of material science applications and users at NERSC. He is engaged in evaluating and improving the suitability of these applications for potential N8 architectures. He additionally works on bringing dynamic web-content to users through MyNERSC, the MOTD system, Completed Jobs Pages, ALS Science Gateway Projects and the NERSC mobile site,

Jack is a PI on a SCIDAC project ( and is one of the lead developers of the BerkeleyGW package for computing the excited state properties of materials.

Jack is the NERSC PI on the Berkeley Lab Directed Research project that is delivering real-time data analysis to ALS scientists through ESNET and NERSC resources. He is the developer the ALS analysis and simulation web-portal at NERSC.

He received a Ph.D. from UC Berkeley in physics in 2011. His research centered on materials physics and nano-science: scaling many-body Green's function computational methods for the study of the optical properties of materials with large and complex structures.
