M.Sc. Stephanie Käs Room 129 Phone: +49 241 8020773 Office hours: Tuesday - Thursday

My current research centers on Human Movement Estimation, especially gesture and action recognition using Large Language- and Foundation Models on monocular (fisheye) images and videos. I have gained significant supervision and teaching experience and place strong emphasis on clear science communication, as well as agile project and group management.

!!! No more HiWi/thesis positions available until Summer 2026!!!
