Short Bio

I received my master's degree in Computer Science from the Vienna University of Technology in May 2014. I wrote my master's thesis at the Complang Group (Institute of Computer Languages). During my studies, I have worked as a teaching assistant for the lectures Database Systems, Functional Programming, and Semistructured Data.

Research Interests

My current research focuses on Continuous Delivery/Deployment and Software Release Processes. I'm interested in the techniques used for rolling out new software features. This includes for example gradual releases (partial rollouts), A/B Testing, and Feature Toggles. Furthermore, I'm working on tools for supporting the automated, strategic execution of such release techniques.
