Research

Research Interests

  • approximation theory, especially nonlinear approximation
  • computational harmonic analysis
  • learning theory, compressed sensing
  • image processing
  • numerical analysis, especially adaptive multiscale methods for operator equations
  • model order reduction methods
  • interdisciplinary applications in fluid dynamics and process engineering

Current Projects

  • Development of novel imaging techniques in electron microscopy (with P. Binev, R. Sharpley, T. Vogt, D. Blom) as well as mathematical learning theory in connection with regression and classification (with P. Binev, A. Cohen, R. DeVore).
  • Multiscale modeling in aerodynamical applications.
  • Reduced basis methods and related model order reduction concepts for non-coercive problems. This is related to the development and analysis of adaptive solvers for transport dominated PDEs (with G. Welper, C. Schwab). An important ingredient here is to establish new well-conditioned variational formulations and their computational realization.
  • Analyzing tensor-sparsity of solutions to high dimensional PDEs like Fokker-Planck equations modeling polymeric fluids (with L. Grasedyck, E. Süli).
  • Development of robust preconditioners for Discontinuous Galerkin methods on locally refined meshes with arbitrary polynomial order (with K. Brix, M. Campos-Pinto, C. Canuto).
