• On April 1, 2015, I moved to Technische Universität München, where I now hold the TUM Tenure Track Assistant Professorship Optimization and Data Analysis at the teaching and research unit M15 Applied Numerical Analysis. My new homepages is here.
  

  My homepage at the University of Göttingen will no longer be updated.

• My paper Improved Recovery Guarantees for Phase Retrieval from Coded Diffraction Patterns, joint with David Gross and Richard Küng, has been accepted for publication in Applied and Computational Harmonic Analysis.
