I am a member of the research group Foundations of Language Processing, which is part of Language Processing Center North. My research interests are formal and natural languages and their analysis, in particular in combination with other modalities such as images and video. One of the current aims is to combine finite-state techniques such as automata and grammars with continuous vector representations. Several of my projects in this area are AI projects targeting multimodal media analysis. In particular, I am interested in ways to create structural representations based on graphs. Examples are automata and grammars that process semantic representations of sentences such as Abstract Meaning Representations, and how those can be made use of for media analysis.

Previously, I have been active in the field of grammatical picture generation. Information about a book on this subject that I have written (in the Springer EATCS series Texts in Theoretical Computer Science) is available here.
