Christopher Ronald Snell, PhD, is the Scientific Director of Workwell Foundation, Ripon, California. He directs the Pacific Fatigue Lab at the Department of Health, Exercise, and Sport Sciences, at the University of the Pacific, Stockton, California, USA.

IOM Committee on Diagnostic Criteria for ME/CFS
Dr Snell was a reviewer for the 2015 report produced by the Institute of Medicine's (IOM) Committee on Diagnostic Criteria for Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS).

Chronic Fatigue Syndrome Advisory Committee
Dr. Snell was Chair of the Health and Human Services's (HHS) Chronic Fatigue Syndrome Advisory Committee (CFSAC) committee from 04/01/07-04/01/11.

Open letter to The Lancet
Three open letters to the editor of The Lancet urged the editor to commission a fully independent review of the PACE trial, which the journal had published in 2011. In 2016, Dr. Snell, along with 42 colleagues in the ME/CFS field, signed the second letter. In 2018, Dr. Snell, with more than 100 colleagues in the ME/CFS field, signed the third letter.
