Senior LevelORAU is part of the NASA Postdoctoral Program, which offers unique research opportunities for talented scientists. The role involves researching and applying statistical methods for uncertainty quantification in simulation-based analysis and design of aerospace vehicles.
Universities
No H1B
U.S. Citizen Only
Responsibilities
Research, develop and apply state-of-the-art nonintrusive statistical methods, including but not limited to dense and sparse quadratures, random sampling and Bayesian statistics to data obtained from high-fidelity, computational fluid dynamics and multidisciplinary simulations
Characterize the uncertainty in output quantities of interest, for example, aerodynamic performance coefficients, range, and acoustic signatures, due to various input uncertainties, such as operating and meteorological conditions, and aircraft shape
Estimate and control numerical and model-form errors to improve credibility of numerical predictions
Handle discontinuities, such as shocks, that may cause multimodal probability densities
Reduce computational cost of many-query UQ methods such that they can be applied routinely in conjunction with high-fidelity simulations
Explore cost reduction strategies including but not limited to multi-level and multi-fidelity approximations, and the use of output gradients
