You will find my office in the MIT building, 4th floor, room E454.
I am primus inter pares of the research group Foundations of Language Processing. My research interests are formal language theory in a wide sense and its application to problems in computational linguistics and natural language processing. In particular, I am interested in structural representations of natural language that combine different aspects such as syntax, semantics, and context knowledge. Currently, I am mostly interested in the algorithmics of automata and grammars that process semantic representations of sentences such as Abstract Meaning Representations.
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.
You may also be interested to have a look at the system TREEBAG.
So far I have been the main supervisor of three PhD students:
- Johanna Björklund (then Johanna Högberg)
- Christina Igasto (then Christina Olsén)
- Martin Berglund
On a more personal note, in my sparetime I keep and breed Dendrobates (also somewhat misleadingly called dart frogs) and I try to develop my photographic skills. Feel free to visit my pages on Dendrobates (in Swedish) and about my photographs.
