About me

Hi there! 👋 I’m Stefan, an ML Engineer working on autonomous driving at Mercedes-Benz.

I have obtained my PhD as part of the Autonomous Vision Group at the University of TĂĽbingen, supervised by Andreas Geiger. You can find my thesis here.

My research is at the intersection of machine learning and 3D Vision, especially motion-based self-supervised learning for 3D LiDAR sensors.

I strongly believe in the Bitter Lesson: In the long run, methods that can make better use of data and compute tend to outperform all the clever tricks we come up with as computer vision researchers. That said, I think motion-based self-supervised learning in 3D is a powerful shortcut for models to obtain a deeper world understanding: It scales with data and compute, while taking advantage of how things actually move and exist in 3D space without requiring any human annotations.
