Grégoire P. Millet is a Professor of environmental and exercise physiology at the Institute of Sport Sciences of the University of Lausanne (ISSUL), he is the author of several books on conditioning, endurance, and altitude training. He (co-)authored over 500 articles including >440 scientific articles in peer-reviewed journals, 6 books, and 45 book chapters. His research has an integrated approach (molecular, animal, and human systemic responses) on hypoxic conditioning for performance enhancement (RSH, LHTLH) and health in patients (obese, hypertension, PAD, preterm-born, neurodegenerescence). He also conducts research on the optimization of interval training; mechanical/physiological coupling in sport locomotion; Assessment/Analysis of fatigue (Neuromuscular and HRV); and Ultra-endurance. His main strength is translating knowledge or methods (e.g. VO2 kinetics, HRV, or hypoxic conditioning) initiated in elite sports to the clinical set-up. He founded and is the co-chief-editor of "Frontiers in Sports and Active Living" and the director of a book collection "je bouge..." for promoting physical activity.
