I joined the Data and Web Science Group in April 2017 as a Juniorprofessor. My research interests are Computer Vision and Machine Learning. More specifically, I am interested in problems such as

  • Learning Graph Embeddings and Graph Representations
  • Neural Architecture Search
  • Grouping Problems (in applications such as Image and Motion Segmentation and Multiple Object Tracking)
  • Efficient Solvers for Large Grouping Problems
  • Motion Estimation
  • Image Generation and Deep Fake Detection

During my PhD with Thomas Brox at the University of Freiburg, I focused on the segmentation in volumetric bio-medical image data.

Ongoing Research Projects
