Biomechanist - Univ. Arizona Professor

Specialties & Experience of this Expert Witness

Additional Information

Dr. Lee-Confer is a biomechanical expert specializing in injury causation, human movement, and walkway safety. As Director of Biomechanics at Verum Biomechanics and Assistant Professor at the University of Arizona, he combines academic research with practical litigation support. His expertise spans: Slip, trip and fall biomechanics (injury biomechanics) Floor slip resistance testing (tribometers) Gait analysis and movement dynamics Code compliance (ASTM, ADA, IBC) Premises liability and safety standards A contributing author to ASTM F2508-16e, the standard for tribometer validation, Dr. Lee-Confer’s work directly informs measurement of walkway slip resistance—a key factor in many slip-and-fall cases. He also played an instrumental role in Arizona Senate Bill SB1373, advancing fall prevention measures. Dr. Lee-Confer holds a Ph.D. in Biomechanics from the University of Southern California, with specialized research in slip detection, motor control, cause of injury to anatomical structures, and fall dynamics. He serves as Vice Chair of Research for ASTM F13 and Commissioner on Disability Issues for the City of Tucson, and actively participates in the ASTM F13 Pedestrian/Walkway Safety and Footwear committee. He provides expert witness services including case review, slip resistance testing, biomechanical analysis, expert reports, depositions, and courtroom testimony.
