MIT-huset, Umeå universitet, MIT.C.444 Umeå universitet, 901 87 Umeå

Min besöksadress är MIT-huset, 4:e våningen, rum E454.

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 såsom bilder och video. Jag är medlem i forskargruppen Foundations of Language Processing, som är en del av Language Processing Center North.

Hittills har jag varit huvudhandledare för tre doktorander:

Johanna Björklund (då Johanna Högberg)
Christina Igasto (då Christina Olsén)
Martin Berglund

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 på med att föda upp pilgiftsgrodor och jag försöker utveckla mina fotografiska färdigheter. Besök gärna mina webbplatser Franks pilgiftsgrodor och Franks foto.
