Short info
I am a fish ecophysiologist interested in understanding how fish cope with climate change, particularly rising temperatures and fluctuating oxygen levels. My research combines both lab and field approaches, and aims to bring the wild into the lab to increase ecological realism in lab experiments.

Momentum Delegate 2026/2027
I am a researcher at the Department of Biological Sciences. As an experimental biologist I research how climate change affects the physiology and behaviour of fish. I completed my PhD at NTNU and since then undertook a postdoc at the University of Glasgow and a second postdoc here at the University of Bergen. Recently I am delighted to have started my own lab group, thanks to funding from the Trond Mohn Starting Grant, where we aim to investigate how ocean warming and declining oxygen levels affect vision and responses to predators in cod.
