Dr. Denis Aslangil joined the Department of Aerospace Engineering and Mechanics (AEM) at the University of Alabama as an Assistant Professor in Fall 2021. Prior to joining AEM, Dr. Aslangil was a postdoctoral researcher at Los Alamos National Laboratory (LANL). He is an expert in turbulence and active scalar turbulent mixing and specializes in high fidelity Large-Eddy Simulations (LES) and Direct Numerical Simulations (DNS). He is also developing physics-informed machine learning turbulence models capable of capturing all physical features relevant to the real flow. His research interests include the theory, modeling and simulation of multi-material turbulence; hydrodynamic instabilities in nuclear fusion, ICF; sub- and super-sonic flows; physics informed machine learning; and high-performance computing.
