Milo Parra-Alvarez joined NREL in July 2020 as a postdoctoral researcher in the High-Performance Algorithms and Complex Fluids Group. In his current role, he develops multiphase computational fluid dynamics (CFD) simulations of algae bioreactors for the production of biofuels and raw materials. He also incorporates physics and data-driven modeling into his CFD analysis for the development of reduced order models, optimization, and uncertainty quantification.

He has a strong background in reacting multiphase flows in RANS and LES, large-scale simulations in high-performance computing environments, and scientific data analysis using uncertainty quantification and machine learning tools. His experience includes the implementation of mathematical and numerical tools to represent gas-solid and gas-liquid flows using statistical techniques, the development of supporting models for overarching multiphase methodologies in open-source code and scientific data, and tool developments to streamline simulation results and scientific analysis.
