My key interest areas are sustainable protein sources in modern aquaculture, fish nutrition and physiology, relationship between novel ingredients and feed processing technology in diets to fish and monogastric animals.

I work with biological assessment of alternative protein sources in diets for farmed fish, from single cell organisms to insects. My methodology include but are not limited to digestibility and growth performance trials and post-prandial blood nutrient profiles in salmonid fish. I have a particular interest in sustainable protein sources, derived from recirculated nutrients and their optimization for aquaculture applications.

As of 2019 I act as a head of feed technology laboratory at HUV where I focus on building competence within feed technology research, not only limited to farmed fish but also other monogastric animals. The laboratory is built around a twin-screw extruder suitable for producing small-scale dry feed batches. Special consideration is given to optimization of feed pellet quality in connection to novel ingredients in recipes for fish and other animals. My goal is to create a bridge between the nutrition and feed research in relation to novel, sustainable protein sources, thus contributing to, and acting as a part of complete biological evaluation platform present at SLU's Department for Animal Nutrition and Management.
