Research Interests: Animal nutrition, particularly in fish, dogs and cats. Protein utilization and alternative protein sources like microbes, mussels and insects to fish. Welfare, physiology, nutritional biochemistry, digestion, metabolism in fish, dogs and cats. Recirculating aquaculture systems and integrated multitrophic aquaculture. Nutrient requirements for novel fish species in aquaculture.

Research Goal: Develop nutrient resources for aquaculture that is not competing with human feed resources and are produced in a sustainable way. Increase knowledge on how to feed fish in a sustainable way, involving specific key questions like effects on performance and welfare after dietary intake of a novel feed ingredient.

Research Skills: Experimental design, feed formulation, sampling, nutrient requirements, protein metabolism, enzymology, animal models (fish) intact and cannulated models.
