Greg Burton has over 20 years experience in the analysis and simulation of turbulent flows. He earned a Ph.D. in 2003 in Aerospace Sciences from the University of Michigan, where as FXB Fellow, he studied computational fluid dynamics under Professor Bram van Leer and turbulence modeling under Professor Werner Dahm. He was one of 8 of 650 doctoral candidates to receive the Rackham Distinguished Dissertation Award in 2004. He continued his research as a postdoctoral fellow at Stanford University’s Center for Turbulence Research between 2003-2005 and in AX Division at LLNL between 2005-2008. He returned to Stanford University to serve as the CTR’s Senior Fellow between 2009-2010. Since returning to LLNL in 2010, he has worked in the Computational Engineering Division where he continues to specialize in developing numerical methods for the simulation of turbulent mixing and reacting flows using large-eddy simulation and Reynolds-averaged Navier-Stokes techniques. He focuses particularly on problems involving hypersonic flows, small-scale mixing, vortex dynamics and buoyancy-driven instabilities using his Nonlinear LES method in massively parallel configurations. He also has a primary role in establishing and running LLNL’s new Turbulence Analysis and Simulation Center (TASC), which specializes in applying advanced turbulence-simulation tools to a wide variety of turbulence, mixing and combustion-related problems encountered at LLNL and in industry.
