Presentation

Currently a research director at the French National Research Agency (CNRS) and head of the Mechanical Engineering dpt at the Interdisciplinary Lab of Numerical Sciences (LISN), part of Paris-Saclay campus, France. I received my PhD (2004) in Applied Math. from Brown University; was a postdoctoral fellow (2004-2005) in the dpt of Ocean Eng at MIT. Research interests: stochastic modeling/computational mechanics, physics-informed machine learning, uncertainty quantification, data assimilation, robust optimization and inverse problems with applications ranging from turbulence, environmental flows and biomechanics
