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 freeform optical surfaces for laser optics by methods of optimal transport (with K. Brix, E. Friebel)
 Development and analysis of adaptive lowrank schemes for highdimensional operator equations (with M. Bachmayr)
 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 noncoercive 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 wellconditioned variational formulations and their computational realization.
 Analyzing tensorsparsity of solutions to high dimensional PDEs like FokkerPlanck equations modeling polymeric fluids (with R. DeVore, L. Grasedyck, E. Süli).
 Development of robust preconditioners for Discontinuous Galerkin methods on locally refined meshes with arbitrary polynomial order (with K. Brix, M. CamposPinto, C. Canuto).
