    Forskningsinteresser

    Mine forskningsinteresser inkluderer seksuell seleksjon (partnervalg), evolusjon, adferd, ornitologi, økologi, økotox og fiskebiologi.

    Har erfaring med eksperimentelle oppsett i felt og lab, samt rene feltstudier hos fulg og fisk. I marine-, ferskvann- og terrestre miljøer.
