I am an independent postdoc at the Institute for Geometry and Practical Mathematics of RWTH Aachen, in Germany, supported by the research center SFB 1481.
My research interests are in approximation of functions, random sampling, optimal recovery, reduced order modeling, high-dimensional approximation of PDEs and inverse problems.
