Wayne Pfeiffer

Wayne (PhD, Engineering Science) has done research in supercomputer performance analysis, and was previously principal investigator for NSF- and DARPA-funded studies to evaluate a novel computer with multithreaded architecture. He also co-led the Joint NSF-NASA Initiative on Evaluation of scalable parallel computers. At SDSC, he has held various senior management positions, including Deputy Director of NPACI, the NSF-funded national partnership led by SDSC. He was also Deputy Director of SDSC, responsible initially for the entire research program and subsequently its technology components.

Ross Walker

Ross (PhD, Computational Chemistry) is formally trained as a computational chemist but has diversified into the life sciences arena. He has extensive experience in Molecular Dynamics simulations and is an active developer of both AMBER and CHARMM. He has considerable experience in porting and optimizing molecular dynamics codes for massively parallel computers. Ross has worked with both message passing and threads-based programming paradigms. His research work is centered on force field development, QM/MM MD development, and enzyme reaction path modelling.
