Om
Jeg er dekan ved Fakultet for natutvitenkskap (NV) siden 1. august, 2025. Jeg var tidligere instituttleder ved Institutt for kjemisk prosessteknologi (IKP).
Jeg har arbeidet som professor ved IKP med spesialkompetanse i industriell krystallisasjon. I krystallisasjonsgruppen studerer vi utfelling og dannelse av faste krystallinske materialer knyttet til industriell produksjon, for eksempel farmasøytiske produkter eller mineralutfellinger. Krystallenes størrelse og form er viktig for separasjonen av og egenskapene til det endelige produktet, og derfor gjør vi grunnleggende forskning på krystallvekstfenomener. Vi samarbeider med industribedrifter, men gjør også grunnforskningsprosjekter innen mineralutfelling i biologiske systemer, som for eksempel hvordan bein dannes i menneskekroppen.
