Scientific Interests

My main research lies in Mathematical Imaging and Optimization. In particular, I am interested in Compressed Sensing as well as Variational Inequalities and Complementarity Problems, and how, using these tools, structures of signal- and data-generating models  can be exploited in Image Analysis and Inverse Problems.

Current Research

  • Tomography From Few Projections: Theory and Algorithms
  • Compressed Motion Sensing with Application to Dynamic Tomo PIV and Echo PIV
  • Structured Regularization for Multi-Channel Signal Recovery
  • Geometry of Multiplicative Iterative Solvers
  • Graphical Model Parameter Learning by Inverse Linear Programming
  • Geometric Image Labeling
