Thomas Olsen

Thomas Olsen is a Research Fellow at the University of Oslo, affiliated with the Faculty of Medicine. His research focuses on sulfur amino acids, B-vitamins, vitamin A, and epidemiology, particularly in the context of metabolic health, obesity, and cardiovascular disease. Olsen holds an MSc in Human Nutrition from the University of Bergen and has prior experience as a nutritional consultant, college lecturer, and guest researcher.

He collaborates with institutions like the University of Oxford, Charles University, and Maastricht University. Teaching includes courses such as MED1100 and ERN3120. His work explores mechanisms linking amino acid metabolism, vitamin status, and metabolic disorders, with a focus on translational research and clinical applications.

Key research areas include the effects of dietary sulfur amino acid restriction on obesity and adiposity, the role of vitamin A in cardiovascular risk, and proteomic adaptations to exercise. Olsen’s studies often involve large cohorts and randomized controlled trials, contributing to EFSA guidelines on nutrient intake levels.

He participates in research groups such as Atherosclerosis and Lipidology and Vitamin B, Amino Acids and Obesity, advancing interdisciplinary approaches to metabolic health. His publications span clinical trials, epidemiological analyses, and mechanistic studies in metabolic and cardiovascular biology.
