Christopher T. Chen, Ph.D., P.E.

Senior Consultant

Forensic Services

Las Vegas

Background

Dr. Christopher Chen received an M.S. and Ph.D. from the University of Wisconsin-Madison for studying musculoskeletal tissue mechanics/medical devices and gained postdoctoral training from Cornell University in the fields of joint mechanics, orthopedics, tissue engineering, and musculoskeletal biochemistry/histology.  Dr. Chen is also a registered professional engineer in multiple states with significant expertise in design and computer simulation/modeling of mechanical systems.

Dr. Chen’s experience includes orthopedic biomechanics, traumatic (sub-traumatic) injuries, and musculoskeletal tissue regeneration such as orthopedic surgical repair of soft tissues (cartilage, ligament/tendon, meniscus, and spinal disc), bone fracture/healing, as well as soft tissue injuries.  He has contributed to more than 100 scientific papers in the field of orthopedics, sports medicine, tissue mechanics, and bioengineering and continues to be involved with teaching biomechanics to graduate/medical students, residents, and orthopedic surgeons.  His studies were supported by the National Institutes of Health (NIH), the Department of Defense (DoD), and numerous research foundations (ANRF, AOSSM, and OREF).

Dr. Chen’s primary areas of consulting expertise include biomechanical/injury consistency, accident reconstruction, medical device product liability, and medical technology.  He uses computer simulations and mathematical models to analyze vehicle dynamics and to perform biomechanical analysis on cases involving in low-speed accidents, sport injuries, and other accidental events.
