Professor vid Institutionen för datavetenskap Roll: Prefekt
Plats
Besöksadress, se karta

Min besöksadress är MIT-huset, 4:e våningen, rum MIT.C.444.

Min forskning handlar om formella metoder med tillämpningar i datorlingvistik och hantering av naturligt språk. Bland annat leder jag och forskar i flera projekt inom AI som handlar om multimodal analys av mediainnehåll. Jag är prefekt vid Institutionen för datavetenskap och hör hemma i forskargruppen Foundations of Language Processing.

Jag handleder ett antal doktorander och har varit handledare för tre doktorander som tagit doktorsexamen:

Johanna Björklund (då Johanna Högberg)
Christina Igasto (då Christina Olsén)
Martin Berglund
Arezoo Hatefi
Adam Dahlgren Lindström

Tidigare har jag varit aktiv inom grammatisk bildgenerering. Information om en bok om detta ämne som jag har skrivit (i Springer EATCS-serien Texts in theoretical Comuter Science) finns här.

Du kanske också är intresserad av att titta på systemet TREEBAG.

På min fritid håller jag bl.a. på med att föda upp pilgiftsgrodor och jag försöker utveckla mina fotografiska färdigheter. Besök gärna mina webbplatser Franks pilgiftsgrodor och Franks fotografier.
