Marc Day manages the High-Performance Algorithms and Complex Fluids Group within the Computational Science Center at NREL. He dedicates his time to developing algorithms for large-scale scientific computations of complex fluid flow problems. Over his career, Marc has contributed to projects associated with compressible and low Mach number astrophysics, compressible and low Mach number terrestrial combustion, and reacting multiphase flows in subsurface porous media. The common theme is the development of highly efficient algorithms that exploit known separations in scale (spatial and/or temporal). In addition, Marc works with uncertainty propagation in large complex applications using techniques based on Markov chain Monte Carlo and implicit sampling, as well as in machine learning with applications in reacting and inert fluid flows.
