My work is connected to the Sea Lice Research Center at UiB within the Fish Health Group.

I have a lot of experience with molecular biology and genetics of salmon lice, identifying new gene functions (1, 2), and identifying the reaction of lice to their environment, like heat or reduced salinity. I have employed RNA-Sequencing to analyse gene expression of salmon lice and their salmon hosts.

I am currently working on the FHF-funded projects Salivax and SaliFilaVax, in which we try to develop and optimise a DNA vaccine targeting the proteins secreted from the salmon louse onto the fish.

I'm also involved in the Microboost project, which is funded by the EEA and Norway Grants and is a cooperation with several portugese partners. In this project we try to use microalgae as functional food ingredient to improve the immune system of fish and prevent lice infestation.

Nanolus is led by Marineholem RASLab AS and is analysing the suitability of ion-modified water as an anti-louse treatment. I'm the project reponsible at UiB and will perform transcriptomic studies on lice treated with this water.

Previously I have worked on the projects Freshnet and Freshnet 2 where we looked at the osmoregulation of salmon lice. Additionally I was involved in the project ModuLus which analysed the interaction of salmon lice and their hosts.
