Research Interests

My main research focus is deep learning-based recognition of human activities and interactions from video streams. I am especially interested in open-set, zero- and few-shot recognition as well as applying the developed models for driver monitoring in intelligent vehicles.

I am involved in the BMBF Project PAKoS (Personalisierte, adaptive kooperative Systeme für automatisierte Fahrzeuge), working on scene understanding inside autonomous cars. The goal of CV:HCI is real-time activity recognition under realistic driving conditions (e.g. varying or low illumination).


Bachelor/Master Thesis

Unfourtunately, at the moment, I am not able to accept new students.

If you are passionate about one of {machine learning, deep learning, computer vision} and want to apply what you have learned in the area of activity recognition / video comprehension in your thesis - please send me an email with a few sentences about yourself.
