Arbeider med

Bruk av genetiske markører i kombinasjon med andre typer data (f.eks. Oseanografi, bathymetri, merkedata osv) for å studere romlig populasjonsstruktur og connectivitet i marine fiskearter.

Pågående arbeid:

Populationsbiologi (økologi/genetikk) til reke, torsk, hummer, sjøørret og flere dypvannsfiskearter (lange, blåkveite, skolest, dolkfisk)
Populationsbiologi til sjøørret (e.g. fødevalg og struktur)
Populasjonsbiologi /genetikk over en naturlig klimagradient (MarinEra)
 

Annet pågående arbeid:

Naturtype og habitatkartlegging i kystsonen
Effektstudier av MPA's
