    Forskningsinteresser

    • Antibiotika, antibiotikaresistente bakterier og evolusjon
    • Klebsiella pneumoniae (Kp) er en sentral aktør i den globale spredningen av antibiotikaresistens. Våre studier involverer komparative molekylære epidemiologiske studier (helgenomsekvensering og metagenomikk) av Kp fra ulike økologiske nisjer inkludert mennesker og dyr, feno- og genotypiske assosiasjoner  i patogenitet og antibiotikaresistens (genomassosiasjonsstudier og maskinlæring), samt prekliniske effekstudier av bakterievirus (bakteriofager) evne til å fjerne bærerskap eller infeksjoner med multiresistente Kp. Kp-studiene er finansiert av Trond Mohn Stiftelsen ( https://mohnfoundation.no/amr-prosjekter/) og partnerinstitusjoner.
