Biography

I work within the EPSRC funded project Score!. Before joining the KRR Group, I worked at the Vienna University of Technology within the Knowledge Based-Systems Group led by Prof. Thomas Eiter. My main research topic there was reasoning with decidable fragments of Open Answer Set Programming. Prior to that, I was with STI/DERI Innsbruck. I have an Engineering Diploma and Advanced Studies Diploma in Computer Science from the Technical University of Cluj-Napoca.
