Subject

I'm working in the field of data-driven control, where I use the Koopman operator to derive closed-loop guarantees for nonlinear systems based on measured data.

Further, I'm working on an autonomously driving e-scooter with the goal of reducing CO2 emissions at the University of Stuttgart.
