Mark VanNess



Dr J. Mark VanNess, PhD, is a member of the scientific advisory committee of the Workwell Foundation which specializes in two-day cardiopulmonary exercise testing (2-day CPET) for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), fibromyalgia and other fatiguing conditions. He has been working on ME/CFS since 1999, and is particularly interested in issues of autonomic dysfunction and mechanisms that produce post-exertional malaise.

Dr VanNess serves as an Associate Professor of Health, Exercise & Sport Sciences, Department of Sport Sciences, and an Adjunct Instructor at the College of Engineering, both at the University of the Pacific, Stockton, California.
