Areas of expertise and interest

I am a marine ecologist working mostly on wrasse. I’m interested in the population dynamics of wild stocks and have studied this using field investigations, mark-recapture studies and age reading (otoliths and scales).

Active projects

Population dynamics of wild wrasse populations along the Norwegian coast (led by Anne Berit Skiftesvik)
