'On voit, par cet Essai, que la théorie des probabilités n'est, au fond, que le bon sens réduit au calcul; elle fait apprécier avec exactitude ce que les esprits justes sentent par une sorte d'instinct, sans qu'ils puissent souvent s'en rendre compte.'
- Pierre-Simon de Laplace, Théorie analytique des probabilités, Paris, Courcier, 1814, 2ème éd.


With the ultimate goal of improving energy efficiency, my research is focused on the development of Computational Fluid Dynamics (CFD) simulations, including Uncertainty Quantification (UQ), for energy systems. I currently work with Professor Jonathan B. Freund at the DOE-funded PSAAP2 XPACC center, where my activities include simulations of combustion & multiphase flows using detailed and reduced submodels of kinetics, transport and laser-plasma ignition. I lead the UQ efforts for the center's main predictions, which involve developments of adaptive UQ algorithms for large-scale computer simulations and model reduction. My UQ research is mainly axed in topics of global sensitivity analysis, building of meta-models, Bayesian parameter estimation, etc. One main objective is to target engineering applications with hundreds of uncertain parameters. I am particularly mindful of industrial needs, and anticipate that my interdisciplinary research projects will have broad impact in efficiency improvement, and Verification & Validation (V&V) in energy systems, as well as in other applied engineering systems.
