Julien’s research examines the physiological mechanisms that impact health and performance in adverse environments (heat and altitude), along with strategies to mitigate their influence and harness their adaptive potential. He has worked with both amateur and professional athletes from various disciplines, along with National and International Federations (FIFA, UCI, World Athletics, and World Triathlon). He has authored over 85 research publications in international journals, including an invited review in Physiological Reviews on exercise under heat stress. Julien has also edited a textbook on Heat Stress in Sport and Exercise.
