About Me

I am a senior researcher at Oracle Labs and an external lecturer at the Johannes Kepler University Linz, Austria (JKU). I finished my PhD at the Institute for System Software (SSW) supervised by Prof. Hanspeter Mössenböck. At Oracle Labs I am working on their optimizing Java compiler Graal (as well as the entire Graal ecosystem).

In my PhD I focused on aggressive compiler optimizations for Java, especially code duplication and loop unrolling.

I am an active contributor to GraalVM and a committee member of the Renaissance Benchmarking Suite
