Exercise Science – sports medicine, exercise physiology, environmental illness


Dr. Koehle’s research program combines exercise and environmental physiology from basic mechanistic research to more clinical field studies in remote environments. He is interested in examining the underlying mechanisms of environmental illnesses such as altitude, heat and decompression illness and developing strategies for their prevention.
