Personal profile

Research interests

Nutritional sensitivity of animal production, health, disease and environmental footprint. My studies range from strategic to applied, addressing research questions in both monogastric and ruminant farm animals but also in laboratory rodents. I am interested in developing discipline-based concepts across species, which form the basis of my research and teaching activities, and is a main driver for our Monogastric Science Research Centre.
