I am a postdoctoral researcher at the Institute for Formal Models and Verification at the Johannes Kepler University Linz. I am doing research into parallelizing SAT-solving and efficient solving of parity games. I like making and improving tools for research, in particular model checking, and searching for better algorithms for open problems. I obtained my PhD (thesis) in the Formal Methods and Tools group at the University of Twente, where I performed research on parallelizing decision diagram algorithms.
