He is currently leading efforts on the verification, validation and uncertainty quantification of wind energy computational models. His research includes wind turbine wake dynamics, the effects of leading-edge erosion and soiling on airfoil and rotor performance, and the functional scaling and design of rotor blades. He received a PhD in Aerospace Engineering from the Pennsylvania State University, where he was an instructor of aircraft design for several years and performed research in applied aerodynamics, wind tunnel testing, and wind turbine aerodynamics.
