Betsy A. Keller, PhD, is a professor in the Department of Exercise & Sport Sciences at Ithaca College in New York. She is a fellow of the American College of Sports Medicine (ACSM), past member of the Board of Trustees of ACSM, and past president and former department chair of the Mid-Atlantic Regional Chapter of ACSM.
Since 2005, she has provided 2-day cardiopulmonary exercise testing (CPET) for persons with ME/CFS for purposes of research and/or to provide an objective assessment of functional capacity and ability to perform and recover following physical work for disability reports. She studies the effects of physical activity in ME/CFS on parameters of physiological and immune function.
In 2015 Keller said "Given what we have learned in the past eight years about this illness, it is intellectually embarrassing to suggest that ME is a psychological illness."
