Curriculum Vitae
Gene expression pattern and level reflects to a significant extent the ongoing anatomical, morphological and physiological activities in a tissue and/or organism. My field of interest is functional genomics in Atlantic salmon with focus on the reproductive mechanisms. We currently use gene editing to knockout (KO) genes in Atlantic salmon , to be able to explore molecular mechanisms related to the reproductive system, in particular germ cell specification and early sexual development, and we have produced sterile fish by ablation of the primordial germ cells or preventing maturation. Both aims explore fields which can result in sterility models for aquaculture that could solve major bottlenecks related to un-wanted sexual maturation and genetic interactions with wild populations. We have also in recent years explored the wild genome pool of Atlantic salmon with the main aim to identify genetic regions under selection for primarily reproductive traits, such as time at maturity and smoltification. However studies have also revealed genetic regions /sweeps that probably confer traits associated with disease resistance, behaviour, sea water adaption and feed metabolism.
