Biography:
Professor Duraisamy is interested in the development of computational models, algorithms and uncertainty quantification approaches with application to the aeromechanics of fixed and rotary wing aircraft, wind turbines and hypersonic cruise vehicles. This research includes fluid dynamic modeling at a fundamental level as well as in an integrated system-level setting. An overarching theme in his research involves the use of computational methods to answer scientific and engineering questions at the desired level of sophistication with an understanding of the effect of modeling uncertainties on the predicted results.
