I am a fisheries biologist at the Marine and Freshwater Institute in Iceland. I am responsible for providing management advice for the commercially exploited lumpfish (Cyclopterus lumpus) population which is targeted for their roe. I am currently investigating the biology of lumpfish in order to provide more informed management advice. Current work focuses on the development of a method for ageing of lumpfish, examining its migratory behaviour through tagging and also investigating its reproductive biology.

Previous work has primarily focused on the reproductive biology of several species (plaice, herring, cod and Greenland halibut) which was performed at the marine laboratory on the Isle of Man and at the University of Bergen.
