Biography Lill Heidi Johansen

I work as a researcher in the field of Fish health. My work implies project and contract research within the areas of pathogen-host interactions and vaccine development I am responsible for the infectious pancreatic necrosis (IPN) challenge model primarily used in contract research for the fish vaccine industry. I am a M. Sc. with some supplementary education from University of Tromsø. My working experience is from fish health research and the fish vaccine industry. For many years I have worked with different problem areas concerning Atlantic salmon and IPN. I also work with intracellular bacteria causing diseases in fish.
