報告摘要：
A review of recent advances in uncertainty quantification (UQ) with application to fluid mechanics and other areas will be presented. UQ is currently one of the fastest growing fields worldwide and in China.
The main UQ framework is based on Wiener chaos expansions and other extensions that allow us to deal efficiently with multi-dimensional systems at a fraction of the computational cost as compared with the Monte-Carlo simulations. The same stochastic modeling approach allows us to examine the effect of random noise and arbitrary perturbations on the stability of flows and other systems.

The Charles Pitts Robinson and John Palmer Barstow Professor of Applied Mathematics, Brown University; also: at MIT and at DOE/PNNL
Professor Karniadakis received his S.M. (1984) and Ph.D. (1987) from Massachusetts Institute of Technology. He was appointed Lecturer in the Department of Mechanical Engineering at MIT in 1987 and subsequently he joined the Center for Turbulence Research at Stanford / Nasa Ames. He joined Princeton University as Assistant Professor in the Department of Mechanical and Aerospace Engineering and as Associate Faculty in the Program of Applied and Computational Mathematics. He was a Visiting Professor at Caltech (1993) in the Aeronautics Department. He joined Brown University as Associate Professor of Applied Mathematics in the Center for Fluid Mechanics on January 1, 1994. He became a full professor on July 1, 1996. He has been a Visiting Professor and Senior Lecturer of Ocean/Mechanical Engineering at MIT since September 1, 2000. He was Visiting Professor at Peking University (Fall 2007 & 2013). He is a Fellow of the Society for Industrial and Applied Mathematics (SIAM, 2010-), Fellow of the American Physical Society (APS, 2004-), Fellow of the American Society of Mechanical Engineers (ASME, 2003-) and Associate Fellow of the American Institute of Aeronautics and Astronautics (AIAA, 2006-). He received the CFD award (2007) and the J Tinsley Oden Medal (2013) by the US Association in Computational Mechanics. His h-index is 64 and he has been cited more than 20,000 times.
Karniadakis is the lead PI of an OSD/AFOSR MURI on Uncertainty Quantification and Director of a new DOE Center of Mathematics for Mesoscale Modeling of Materials (CM4).
