Possible effects of polyunsaturated fatty acids (PUFA), especially long-chain n-3 PUFA in relation to cardiovascular risk markers, metabolic syndrome, immune function, gut microbiota, growth and development. Current new interests are diet-gene-interactions and interactions between intake of PUFA and other nutrients.

Has over the years been involved in teaching in biochemistry, cell toxicology, signal transduction, essential fatty acid biology, infant nutrition, and evaluation of scientific evidence. Teaching forms has included lectures, practical hand-on- and theoretical courses and counselling in relation to various types of trainee research projects and has been performed at bachelor, master as well as Ph.D. level in relation to different educations within the natural sciences and health.
Teaching responsibilities also include coordination of master courses currently in “Evidence, Diet & Health”. Is furthermore a member of the education board for the nutrition educations at KU-LIFE and for the Bachelor education in Nutrition and Health at University College Metropol.
