James M. Miller, PE, PhD

Dr. Miller is an Emeritus Engineering Professor at the University of Michigan and a registered mechanical professional engineer with over 30 years of experience. He has served as a consultant to industry and government and is highly qualified to give engineering testimony. He and his engineering staff specialize in: designing warnings, instruction manuals and labeling (including the new OSHA-12 GHS requirements); auto and truck accident reconstruction; mechanical and electrical safety; fire, explosion and chemical process accident analysis; slip and fall prevention; marine, swimming and recreational vehicle accidents (boats, ATVs and personal watercraft); farm accidents, and compliance with governmental and consensual safety standards (OSHA, ANSI, ASTM, UL, CPSC, ASABE).

Dr. Miller has recently authored a chapter titled “Hazard Communication Compliance” in the American Society of Safety Engineering Safety Engineering Handbook. Dr. Miller has also authored five books on the topic of Warnings and Safety Instructions and written numerous journal articles.  He is also currently a committee member of the ASTM Technical Committee F15 on Consumer Products.

He holds a Bachelor of Mechanical Engineering and Ph.D. in Industrial Engineering from Ohio State University, where he was one of the first US PhD graduates specializing in transportation and consumer accident research. He became a professor at the University of Michigan’s Department of Industrial and Operations Engineering (IOE), where he taught courses in human factors/ergonomics, safety engineering, methods engineering and law for engineers (1970-1998). On leave from the University (1975-1977) at the U.S. Department of Labor, he was appointed as Special Assistant for Safety to OSHA’s Assistant Secretary of Labor, where he had responsibility, among other things, for revising the OSHA General Industry (29CFR1910) and Construction (29CFR1926) Safety Standards. He also participated in the early formation of the OSHA HazCom standard (29CFR1200) and original chemical labels and MSDS sheets.
