Dr. Lindsay W. Dutch Johnson is the Director of Research for the TORIS organization and President and principal engineer of Wiltshire Analysis, Inc.—a Phoenix, Arizona-based company that specializes in investigating and analyzing accidents to determine injury causation. His expertise is in the field of injury biomechanics, including the analysis of human injury, human injury tolerance, and accident reconstruction testing. Dr. Johnson has used his expertise in biomechanics and mechanical engineering to solve a broad range of problems related to accident investigation and failure analysis, including falls due to tripping, slipping, and load bearing structural failure, as well as impacts from projectiles and human-to-human collisions.

Dr. Johnson has specific expertise in describing normal human movement and human response to injurious events; how people are injured and what tolerances humans have for injury; and identifying the contribution of the surroundings to the injury event. Dr. Johnson also has expertise in accident reconstruction testing with instrumented anthropomorphic test devices (i.e., test dummies), and data analysis. Dr. Johnson has performed research in the areas of mechanical property characterization of human soft tissues and impact loading of athletes.

Prior to starting Wiltshire Analysis, Inc., Dr. Johnson worked as a Senior Engineer at Exponent’s Test and Engineering Center in Phoenix, Arizona. While at Exponent, he used his expertise in engineering analysis and testing to solve a multitude of problems related to accident investigation and failure analysis. Prior to joining Exponent, Dr. Johnson was a researcher at the Biomechanics Laboratory at the Georgia Institute of Technology (Georgia Tech).

Dr. Johnson earned his Ph.D. in Mechanical Engineering (Biomechanics) from the Georgia Institute of Technology (Georgia Tech) where he was also a Parker H. Petit Bioengineering Fellow, and his M.S. in Mechanical Engineering (Biomechanics) and B.S. in Mechanical Engineering, both from Oregon State University.

A member of the American Society of Mechanical Engineers, Dr. Johnson is also a member and reviewer for the American Society of Biomechanics. Dr. Johnson also testifies in court as an expert in biomechanics.

In addition to mechanical engineering and biomechanics, Dr. Johnson also served a 3-year active duty enlistment in the U.S. Marine Corps. During this enlistment, he received multiple Expert shooting qualification awards with the M16A1 rifle, and maintained ‘300’ physical fitness test (PFT) scores through out his enlistment.

Dr. Johnson has developed his teaching expertise as a lifelong pursuit—teaching both Experimental Methodology in Mechanical Engineering and Mechatronics at Georgia Tech, for which he received The George W. Woodruff School of Mechanical Engineering outstanding GTA award in 1998; leading platoon physical conditioning as a NCO at Camp Pendleton; and earning his Instructor credential in 2007 after working directly with TORIS Instructors.

He began studying with TORIS-developed curricula in 2003. Dr. Johnson specifically focused on the lethal force program as Director of Research (injury biomechanics) for TORIS in 2007—the same year he became an Instructor. Since that time, Dr. Johnson has authored the book Practical Injuries: Sites, Mechanisms, and Results, and has assisted in shaping the TORIS curricula—applying unprecedented research to expand the knowledge base surrounding lethal force options available to military and law enforcement personnel.
