About Me

Since April 2022 I am working as a PhD student at the Chair of Software and Systems Engineering (Prof. Dr. Pretschner). Prior to joining the chair, I completed my Master’s degree in Software Engineering, in an elite graduate program hosted by TU Munich in cooperation with the Ludwig-Maximilians University Munich and the University of Augsburg.

My area of research is integration testing of microservice systems.


Thesis Supervision

If you are interested in working with us, have a look at our theses openings page or at my currently open topics below (I try to keep them up-to-date).

In case you have an interesting idea in the context of (integration) testing of microservice systems, feel free to contact me directly!
