Biography
George 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 has a joing appointment with PNNL since 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 SIAM CSE/ACM prize (2021), the SIAM Ralf E Kleinman award (2015), the (inaugural) J. Tinsley Oden Medal (2013), and the CFD award (2007) by the US Association in Computational Mechanics. His hindex is 118 and he has been cited over 62,500 times (see his google scholar citations). You can also check out his Geneaology Tree (remember to zoom in!). Here is his wikepedia profile.
 Karniadakis is currently the lead PI of an OSD/ARO/MURI on Fractional PDEs, and previously the lead PI of an OSD/AFOSR MURI on Machine Learning for PDEs. He is also the Director of the DOE center PhILMS on PhysicsInformed Learning Machines and previously he was also the Director of the DOE Center of Mathematics for Mesoscale Modeling of Materials (CM4).
Research Interests
His current research interests are on machine learning for scientific computing (Scientific Machine Learning), that is how to solve and discover new PDEs via deep learning, hence removing the tyranny of grids and using gappy data only. Check here to find how to use deep neural networks to solve the Schrodinger equations with only 10 lines of Tensorflow code! Check here to see how to use deep CNN to classify different types of red blood cells in sickle cell anemia.
His broad research interests focus on stochastic multiscale mathematics and modeling of physical and biological systems. Current thrusts include probabilistic numerics, stochastic simulation (in the context of uncertainty quantification and beyond), fractional PDEs, and multiscale modeling of complex systems (e.g., the brain). Can you believe that we solve problems in 100 dimensions  check this out! Read here about our work on sickle cell anemia and also on modeling malaria from first principles, which was also featured on the web site of the National Public Radio. Read also about our work on the first large multiscale modeling of a brain aneurysm (finalist in the Gordon Bell Award, Supercomputing'11). Our new area is neurovascular coupling in the brain, i.e., bridging the gap between neuroscience and vascular mechanics. New experimental evidence suggests the intriguing possibility that by slightly modulating the brain blood flow one can control information processing  read our paper here!

A new report by the National Research Council points to the philosophy and direction of my group, practiced over the last 25 years. (Thank you NRC!) Here's a brief sample: "...But the value of the mathematical sciences to the overall science and engineering enterprise and to the nation would be heightened if the number of mathematical scientists who share the following characteristics could be increased: (1) They are knowledgeable across a broad range of the discipline, beyond theirown area(s) of expertise; (2) They communicate well with researchers in other disciplines; (3) They understand the role of the mathematical sciences in the wider world of science, engineering, medicine, defense, and business; and (4) They have some experience with computation..."
