    Research interests

    (Tidligere aktiviteter)

    Mine forskningsinteresser inkluderer struktur-funksjonsstudier av proteiner (enzymer): Hvordan påvirker den atomære strukturen enzymers aktivitet, spesifisitet og effektivitet. Enzymer med opprinnelse i kuldetilpassede organismer har ofte helt unike biokjemiske egenskaper, og disse ønsker man kunne anvende i biokjemisk og bioteknologisk industri.
