Job description

Jeg er direktør for Visual Intelligence. Dette er et Senter for Forskningsdrevet Innovasjon (SFI) innen kunstig intelligens finansiert for 8 år av Norges forskningsråd og et konsortium av private og offentlige partnere (prosjektnr. 309439). Vi er i den internasjonale frontlinjen innen forskning på dyp læring for bildeanalyse spesielt og multimodal læring generelt. 

Min hovedstilling er som Professor i Forskningsgruppa for maskinlæring ved UiT.

Jeg er også ansatt som Adjunct Professor ved: Pioneer Centre for AI, University of Copenhagen & Norwegian Computing Center.

For en kort CV, se "Vedlegg".

Fremme vår felles framtid gjennom forskning

Min motivasjon er å bidra til løsninger for de store samfunnsutfordringene i vår tid innen helse, marin kartegging, bedre utnyttelse av energiressurser og presis observasjon av jorda. Jeg har omfattende samarbeid med industri og offentlige aktører. Min metodologiske forskning har fokusert på emner som nevrale nettverk, informasjonsteoretisk læring, "kjernemetoder", ikke-styrt læring, selv-læring og forklarbar AI (XAI). Min forskning publiseres jevnlig innen de mest sentrale konferanser og journaler innen feltet (ICLR, ICML, NeurIPS, etc). Jeg har vært heldig å jobbe med mange dyktige kolleger, og sammen har vår forskning blitt anerkjent i feltet:
