Chris Chang is a senior scientist with NREL's Computational Science Center. He recently led the benchmarking effort for the Eagle high-performance computing (HPC) procurement and development of the technical requirements for the ESIF-HPC-3 procurement. He has worked on complex electronic structure of transition metal systems, macromolecular dynamics, comparative chemical bonding analysis, electron transfer, and HPC for systems biochemistry. His current activities include assessment of quantum computing potential; research on electronic structure for QIS; photochemical dynamics of lanthanide metal complexes; enabling complex and/or accelerated workflows for data science and simulation on local and cloud resources; and, leading the HPC User and Application Support Team.
