Welcome to my homepage

I am a professor of computational linguistics, which means that I am interested in computer systems that understand, produce, and translate human language, as well as in the mathematical and algorithmic theory underlying them.

Before coming back to Saarland University, I was professor of theoretical computational linguistics at the University of Potsdam. I was also a postdoc at Columbia University and the University of Edinburgh.

Research and teaching

My research interests are broad. They encompass coming up with clean mathematical models for natural language phenomena and efficient algorithms for solving useful problems in natural language processing. In particular, I have done quite a bit of research on computational semantics, grammar formalisms, and natural language generation (NLG).

Of my past teaching, I'm particularly proud of the talking robots projects I supervised together with Geert-Jan Kruijff.
