I am an institute postdoc at the Institute for Computational and Experimental Research in Mathematics (ICERM) in Brown University.
My research interests are in approximation of functions, random sampling, optimal recovery, reduced order modeling, high-dimensional approximation of PDEs and inverse problems.
I was previously a postdoc at the Institut für Geometrie und Praktische Mathematik (IGPM) of RWTH Aachen, in Germany. Before that, I did my PhD at Laboratoire Jacques-Louis Lions, in Sorbonne Université, Paris.
