H. Harvey Cohen, Ph.D. CPE

Founder (retired)

Harvey Cohen founded Error Analysis, Inc. having recognized a need in the U.S. legal system for scientist-practitioners with expertise who could truly and accurately describe the complex nature of causation of serious injuries in major incident and catastrophes. Harvey Cohen served many courts in North America from the late-1980s to the late 2010s, significantly advancing forensics through his human factors and safety research and its application to scientific and professional inquiry in claims and litigation, most notably in the areas of occupational safety and personal injury.

Following an early career at the Langley Research Center of the National Aeronautics Space Administration (NASA) and the National Institute for Occupational Safety and Health (NIOSH) in the 1970s, Dr. Cohen in the 1980s co-led Safety Sciences (San Diego, CA) on human factors and safety research funded under contract by various public and private sources. He later formed Cohen and Associates (which later incorporated as Error Analysis, Inc.) to further its litigation practice. Over the next 30-plus years, Dr. Cohen served as a subject matter expert and/or consultant to legal practitioners in nearly all 50 states in America, four U.S. territories (e.g., Guam), and three Canadian provinces.
