Dr. Joseph Oefelein is a professor in the Daniel Guggenheim School of Aerospace Engineering at the Georgia Institute of Technology. He joined the faculty at Georgia Tech. in the fall of 2017, after a 17-year career at Sandia National Laboratories, Combustion Research Facility, where he served as a distinguished member of technical staff. Prior to this, he served as a research associate in the Department of Mechanical Engineering at Stanford University. He is actively engaged in research on a broad range of topics in simulation and modeling of advanced propulsion, power, and related systems. His expertise is interdisciplinary, with focus on the theory and analysis of complex fluid flows where turbulence interacts with a multitude of strongly coupled fluid dynamic, thermodynamic, transport, chemical, multiphase, and/or heat transfer processes. He is an expert in the area of supercritical fluid phenomena and has extensive experience in the development and application of the Large Eddy Simulation (LES) technique, Computational Fluid Dynamics (CFD), and high-performance massively-parallel computing. He is active in a number of professional societies including The Combustion Institute, American Physical Society (APS), American Institute of Aeronautics and Astronautics (AIAA), American Society of Mechanical Engineers (ASME), and Society of Automotive Engineers (SAE). He is an associate editor for the Journal of Propulsion and Power, and a member and past chair of the AIAA Propellants and Combustion Technical Committee. He also serves on the editorial board of The Combustion Institute and as an associate editor for the Proceedings of The Combustion Institute. Dr. Oefelein has been a principal investigator for a broad range of sponsored research projects funded by the United States  Department of Energy, Department of Defense (e.g., AFOSR, AFRL, DARPA, SERDP), National Aeronautics and Space Administration (e.g., MSFC, LaRC), and National Science Foundation. He has also established significant collaborations with key industry leaders in the aerospace and transportation sectors. The portfolio of projects involves research across a broad range of topics while also providing a crucial link between basic and applied research.
