I am currently a Ph.D. Candidate under the supervision of Prof. Mathias Niepert at Max Planck Research School for Intelligent Systems (IMPRS-IS) and University of Stuttgart. I have also been a Researcher at the German Research Center for Artificial Intelligence (DFKI) since 2021.
My topics of interest are
- Hybrid Discrete-Continuous Learning (differentiable relaxations for discrete intermediate representations)
- Scalable Algorithms for Multi-modal Learning with applications for Healthcare, Simulation Science
- Efficient Deep Learning (model compression, accelerated training/inference, etc.)
