Bengt Kayser is director and full professor at the Institute of Sports Sciences of the University of Lausanne in Switzerland. After his medical studies at the University of Amsterdam in the Netherlands he engaged in an academic career in the field of exercise physiology with a special interest in hypoxia. After obtaining his PhD at the Free University of Amsterdam, Netherlands, he worked at McGill University in Montreal, Canada, before joining the University of Geneva in Switzerland. After preparing the merger of the Lausanne and Geneva institutes of sports and movement sciences he now is at the University of Lausanne since 2013. His research interests concern the factors limiting endurance exercise performance, altitude medicine and physiology, respiratory mechanics during exercise, doping and anti-doping, and the relationship between physical activity, energy balance and (public) health and its determinants in different settings.
