Staci Stevens holds a bachelor's degree in Sports Medicine and a master's degree in Exercise Physiology from the University of the Pacific in Stockton, California. Ms. Stevens, in conjunction with Workwell Foundation's research team, pioneered the use of two-day cardiopulmonary exercise testing (CPET) in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) to document the hallmark clinical feature of the illness, post-exertional malaise. She served on the Department of Health and Human Services's Chronic Fatigue Syndrome Advisory Committee and as vice president of the International Association of CFS/ME. Ms. Stevens co-authored a ME/CFS primer for clinical practitioners, ME International Consensus Criteria, and is a co-recipient of two publication awards from the California Physical Therapy Association for research in ME/CFS. Workwell is a collaborator with the National Institute of Health's (NIH) ME/CFS Intramural Study, NIH ME/CFS Collaborative Research Center, and a member of Cornell's Center for Innervating Neuroimmune Disease. Her clinical experience includes utilizing CPET for disability evaluation and activity management programs. She aims to functionally characterize ME/CFS, educate health care professionals, and improve quality of life for patients.
