Yiannis Andreopoulos


Yiannis Andreopoulos held postdoctoral research appointments at the University of Karlsruhe, Germany, and at Princeton University. His research expertise is in the areas of fluid dynamics which impact transportation, manufacturing, medicine, biology, energy, the environment, and defense and homeland security. He has developed several unique experimental techniques and designed a large-scale wind tunnel and a high energy/enthalpy experimental shock tube research facility for compressible flow studies in various configurations where high spatial and temporal resolution is required. In the last five years, he has been involved with research focusing on the interaction of fluids with soft compressible porous media. He has conducted theoretical, computational and experimental research on the aero-elastic interaction of shock waves with monolithic, composite and porous materials.
