Åshild Krogdahl was educated in human nutrition with a PhD addressing effects of legume protease inhibitors on digestive functions. Thereafter, as researcher, associate and full professor in animal nutrition, her focus, besides teaching, has been monogastric animal nutrition, with an emphasis on physiological and health impacts of antinutrients, new feedstuffs, and additives. In recent years salmon has been the main species of investigation. Of the many research projects she has led, the most comprehensive was the management of the Gut Health unit of the Aquaculture Protein Centre, a CoE. She has served as member and leader of committees at NMBU, under the Norwegian Research Council, and two periods as leader of the Steering Committee of the Norwegian Scientific Committee for Food Safety.
