Dr. Phillip J. Wolfram is a computational fluid dynamist in the Theoretical division Fluid Dynamics and Solid Mechanics group at Los Alamos National Laboratory with expertise in numerical methods and modeling of small- and large-scale environmental flows. His work has centered on understanding mixing processes within complex flows, most recently for secondary flows in channel networks in the Sacramento San Joaquin Delta and geostrophic turbulence in idealized Northern Atlantic and Southern Ocean flows. He uses fluid mechanics, algorithms, high-performance computing, software engineering, and advanced visualization techniques to increase knowledge of computation, analysis, and the physics of complex, eddy-driven mixing processes, with emphasis on coastal and climate applications. He is an expert in development and application of unstructured computational fluid dynamics, especially nonhydrostatic processes and in-situ Lagrangian particle tracking techniques.
