About me

I studied Computer Science at TU Wien (Vienna University of Technology) and received my diploma in February 2001. In May 2003, I received my PhD in Computer Science. From July 2001 to May 2007 I was working as a project research assistant in the Knowledge-Based Systems Group. Since June 2007, I am an assistant professor at the Database and Artificial Intelligence Group. In November 2008, I received my Habilitation in the area of ``Information Systems'' at the Faculty of Computer Science of TU Wien. From August 2013 to January 2015, I have been associate professor at the Database and Artificial Intelligence Group. In Winter Term 2013, I held a deputy professorship at Leipzig University. Since February 2015, I am full professor for "Formal Foundations of Artificial Intelligence" at the Database and Artificial Intelligence Group. Since January 2020, I am head of the group and Vicedean of Academic Affairs of the Faculty of Computer Science. Since 2022, I act as co-director of the Center for Artificial Intelligence and Machine Learning (CAIML) of TU Wien.

Current projects I am involved in:

Previous projects (selection):

CV (in German); and a shorter version (in English).


My research concentrates on problems in the areas of Knowledge Representation and Reasoning; complexity analysis in AI, Logic Programming, and the Semantic Web; design and analysis of algorithms.

Selected Publications (at the DB&LP Bibliography Server).

Awards: In 2002, I received the OCG-Förderpreis, an award for oustanding master theses in the field of Computer Science (Photo). Best paper awards at RR'10, COMMA'10, KR'12 (distinguished student paper prize) (Photo), and ICLP'21. In 2013, I received the prestigous START Prize of the Austrian Science Fund (FWF) (Photo). In 2018, I became a fellow of the European Association for Artificial Intelligence (Photo).
