About
Before joining Prof. Pretschner's chair in July 2019, I worked in several positions as software and machine learning engineer. My research focus is on software testing in general and more precisely on regression test optimization in continuous integration environments.
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).
I am looking for students with a strong background in programming (Java, C/C++, Rust) and high motivation to dig deep into regression testing, dynamic/static code analysis, compiler infrastructure, and continuous integration.
In case you have an interesting idea referring to my research areas, please feel free to contact me directly!
