Derek Vigil-Fowler

Research Scientist: High Performance Computing | 303-384-6635

Dr. Vigil-Fowler is an expert in high performance computing and high-fidelity simulation methods for materials physics and chemistry, with particular expertise in post-DFT, high accuracy methods such as the GW approximation for electronic structure and random phase approximation (RPA) total energies for total energies and reaction energetics. He has done pioneering work on pushing the state of the art in computational methods, including efficient methods for including the effects of substrates on electronic structure in a computationally tractable way, novel parallelization schemes for GW/RPA calculations, improving threaded performance and parallel I/O of the the BerkeleyGW package for exascale applications,  and recent work on calculating RPA total energies on complex surface chemistry. He is a developer of the massively-parallel BerkeleyGW computational package. 

Dr. Vigil-Fowler is currently applying his expertise in high performance computing to his traditional area of expertise (materials science and chemistry), as well as branching out to applications in wind turbine simulation, power systems, and data science.
