Ryan M. Chapman, PhD
Ryan began his career as an engineer by earning his undergraduate baccalaureate degree in electrical engineering from The University of St. Thomas in St. Paul, Minnesota. Following professional work in the sporting goods industry, he earned a Master's degree from the University of Iowa in Biomedical Engineering with a focus on human motor performance and upper extremity biomechanics. After successfully re-tooling the University of Virginia Sports Performance (SPEED) lab, he joined DBEC as the resident biomechanics expert. His current research efforts are focused on developing medical devices to better diagnose/treat pathologies with symptomatic movement patterns. This includes better characterizing the in-vivo biomechanics of individuals both in and outside the clinic/lab including patients undergoing arthroplasty procedures, athletic injury mechanisms, gait in expectant mothers, and trauma.

Barbara H. Currier, MChE
Barbara began her work in orthopaedic device research in 1994 when she joined the Dartmouth Biomedical Engineering Center. Since 1994, she has been involved in the study of polyethylene bearings in hip and knee prostheses. Current research work is focused on investigating the factors influencing fatigue damage in the knee, and also the shelf and in vivo oxidation processes in UHMWPE bearings, using FTIR spectroscopy, uniaxial tensile testing, and numerical modeling. She has been the lead researcher and author of a number of recent studies on the in vivo performance of UHMWPE bearings.

John H. Currier, MS
John began his association with Dr. John Collier and his early work on hip prostheses in 1979. After spending a number of years working in both production and research for the petroleum industry, he returned to Dartmouth Biomedical Engineering Center in 1994. He has been involved in the study of polyethylene bearings in hip and knee prostheses. Current research work is focused on investigating wear and damage in knee bearings, the shelf and in vivo oxidation processes in UHMWPE components, and the performance of ceramic hip bearings.
