Vår forskningsgruppe prøver å forstå hvordan stress fører til celledød og hvilke mekansimer cellene har for å beskytte seg selv og omliggende celler. Vi bruker zebrafisk som in vivo modell for å studere signaler som fører til celledød og beskyttelse. Zebrafisk er blitt en svært populær modell for menneskelig sykdommer. Zebrafiskens utvikling og organer er like våre og sykdomsrelaterte menneskelige gener finnes som funksjonelle gener også i zebrafisk.
