Project Personnel

The essential asset of any successful enterprise is its people!The RERC staff possesses knowledge and expertise in wheelchair transportation safety and technology that is recognized worldwide. Similarly, those individuals who serve on the RERC's Advisory Board hold wheelchair transportation safety at the forefront of their interests. 

Key Investigators

Lawrence W. Schneider, PhD, RERC Director, holds BSE and MSE degrees in mechanical engineering and a Ph.D. in bioengineering from the University of Michigan.  Since completing his doctorate in 1973, he has been employed at the University of Michigan Transportation Research Institute (UMTRI) where he is currently a Research Professor and Head of the Biosciences Division.  He also holds an appointment in the Bioengineering Department at the University of Michigan.  Over the past thirty-three years, Dr. Schneider has served as project director and principal investigator on more than one hundred research projects dealing with the biomechanics of injury and the biomechanics of occupant positioning and seating in the automotive environment.  For the past fifteen years, Dr. Schneider has directed UMTRI’s in-depth crash investigation program, which identifies the causes of injuries in different types of crashes and assesses the performance of the latest restraint and crashworthy technologies.  Dr. Schneider recently developed a new method for documenting injury causation scenarios that is being used by the Crash Injury Research Engineering Network (CIREN), a nation-wide trauma-based crash-investigation program sponsored by the National Highway Traffic Safety Administration (NHTSA) and the automotive industry.

Perhaps of greatest importance to the goals of the RERC WTS, Dr. Schneider has been involved for more than twenty-eight years in the application of basic principles of occupant protection and biomechanics to providing safer transportation for wheelchair-seated occupants. Since 1978, he has conducted over one thousand sled impact tests of wheelchairs, wheelchair tiedowns, and occupant restraints.  He was instrumental in the formation of the SAE Restraint Systems Task Force of the Adaptive Devices Subcommittee (ADSC) in the mid 1980s, and was the principal author of SAE J2249 Wheelchair Tiedowns and Occupant Restraint Systems for Use in Motor Vehicles and the comparable ISO standard 10542-1 and –2.  He was also the principal author of Section 19 ANSI/RESNA WC/Volume 1 Wheelchairs for Use as Seats in Motor Vehicles and is the current Chair of the RESNA Committee for Wheelchairs and Transportation (COWHAT).
