Short Bio

I was a PhD student and, briefly, a Postdoc at the Software Evolution and Architecture Lab ( s.e.a.l.) led by Harald Gall between September 2016 and July 2021, defending my dissertation "Deliberate Microbenchmarking of Software Systems". I mainly worked with Philipp Leitner on topics at the intersection of performance and software engineering.

I received my bachelor's degree in Media Technology/Interactive Media from FH St. Pölten and my master's degree in Software Engineering and Internet Computing from TU Wien.
