We recently moved to the University of Siegen. Visit our new page here.
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.
