About Us

WE PREDICT HUMAN INJURY IN ANY ENVIRONMENT

Our Forensic Investigation services specialize in injury biomechanics, incident reconstruction, and product safety to determine injury causation and prevention. We are confident in our ability to report these findings and testify our expert opinions in a court of law if necessary.

Our Research & Training services specialize in research to evaluate existing products, supporting our clients in new product development, and providing our Continuing Professional Development Training that focuses on the Science of Violence®.

Typical clients include:

  • Safety Product Companies
  • Legal Professionals
  • Police Officers
  • Social Workers
  • Engineers
  • Health Professionals

When our Principal, Geoffrey Thor Desmoulin, Ph.D., R.Kin., P.L.Eng., opened GTD Scientific Inc. in 2009 his goal was simple: Provide the highest quality biomechanical consulting services available.

Since then, we have earned Federal and Supreme Court qualifications along with an extensive local, national and international client list.

With two degrees in Kinesiology and two in Engineering with a sub-specialty in the Science of Violence®, Geoffrey has a unique skill set perfectly suited for understanding human injury from a biomechanical perspective.

A man of many talents, he has previous experience as an international athlete in the sport of biathlon (cross-country skiing and shooting), emergency medical technician, firefighter, karate black belt, and was the former engineering expert on Viacom’s hit TV series, Deadliest Warrior.

Geoffrey draws on his decades of practical, hard-earned experience gained while investigating a wide range of criminal and civil cases, as well as research projects that enabled him and the team at GTD Scientific to further expand their knowledge base.
