Research Interests

My primary research interest is in the development and application of numerical methods to simulate fluid flows related to aerospace vechicles and renewable energy systems. Currently, I am spending a good deal of my time towards numerical error estimation and uncertainty quantification in computational fluid dynamic formulations with application to a variety of areas including fixed and rotary wing aircraft, wind turbines and hypersonic cruise vehicles.
