Kathryn Dainty Davis, Ph.D.
Managing Scientist
Biomechanics
  • Los Angeles

Dr. Davis has over four decades of expertise in injury biomechanics and human movement analysis. Her analyses have included consulting in cases involving motor vehicle accidents; pedestrian impacts; slip, trip and falls; falls from height; boating accidents; sports injuries, and industrial accidents. Prior to becoming a consultant, Dr. Davis was a professor and administrator at universities and colleges in both Canada and the United States. Dr. Davis taught biomechanics and anatomy to both undergraduate and graduate students. Her initial research endeavors were related to sports in terms of injury prevention and performance enhancement. She served as a biomechanics consultant to both the Canadian Figure Skating Association and the Canadian National Alpine Ski Team. Working with a colleague at the University of Ottawa, she investigated the chest deflection characteristics of anthropomorphic test devices (ATD’s) as they relate to live human chest characteristics.

Dr. Davis moved to California and helped establish an impact laboratory at the University of California, San Diego, with a grant from the National Highway Traffic Safety Administration (NHTSA), performing full scale sled impacts with both ATD’s and post mortem human subjects. After two years as a NHTSA grantee in California, she was recruited to be the Academic Dean of the Canadian Memorial Chiropractic College in Toronto where she remained for the next ten years. During this time she held adjunct appointments at both the University of Toronto and the University of Waterloo, teaching some biomechanics courses and continuing with research in ergonomics and product safety.

In 2000, Dr. Davis returned to California as a biomechanics consultant. During her career, she has published a number of articles in the peer reviewed literature, co-authored a text book on Fundamentals of Biomechanics, published articles in public journals, and made several presentations both nationally and internationally. Dr. Davis has served on review boards and was a member of both the American and Canadian Councils on Chiropractic Education setting standards and visiting colleges to ensure compliance. She is currently a member of the ASTM F13 Committee on walkway safety and has held certification as a tribometrist utilizing the English XLT tribometer. She is also a Certified Forensic Consultant through the American College of Forensic Examiners.
