Short Bio

André van Hoorn is a researcher and Ph.D. student with the Software Engineering Group at the University of Kiel. He was member of the Graduate School on Trustworthy Software Systems (TrustSoft) at the University of Oldenburg, where he was holding a PhD scholarship. He studied computer science at the University of Oldenburg.  His research interests include software performance engineering and software architectures. Particularly, he is interested in performance modeling, testing, monitoring, and evaluation, as well as architecture-based runtime adaptation of software systems for increased resource efficiency.
