John R. Johnson is deputy division director of PNNL's Advanced Computing, Mathematics & Data Division, where he leads high performance computing and large scale data analytics research for national security. Prior to joining PNNL, he was a senior technology/investment manager for the world's largest global macro hedge fund. In that role, Johnson led computational programs in portfolio construction and optimization focused on risk controls and compliance, market signals processing, netting and transaction costs, trade checks and release for execution, FX and Treasury hedging, and options.

Before that, Johnson was a research program manager with the Center for Applied Scientific Computing at Lawrence Livermore National Laboratory (LLNL), where he led multiple programs exploring novel and emerging computing architectures and progressive algorithms for data-intensive applications of relevance to the national security community. As part of the DOE's Accelerated Strategic Computing Initiative, he was the CS technical lead for a massively parallel, high-fidelity physics simulation project at LLNL, earning a DOE Weapons Recognition of Excellence Award. Johnson also led projects in climate modeling and simulation as part of LLNL's Program for Climate Model Diagnosis and Intercomparison.
