James Johnston

James Johnston is a Professor in the Department of Mechanical Engineering at the University of Saskatchewan, with a specialization in Biomedical Engineering. He holds a BSc(Eng) from the University of New Brunswick (1999), an MSc(Eng) from Queen's University (2001), and a PhD from the University of British Columbia. Johnston joined the University of Saskatchewan in 2008 and is affiliated with both the Applied Mechanics and Machine Design and Biomedical Engineering research groups.

His educational background includes a strong foundation in mechanical engineering, followed by three years of practical experience at the Institute of Orthopedic Research and Education in Houston, Texas, where he worked as a biomedical research engineer between his MSc and PhD studies.

Johnston's research focuses on orthopaedic biomechanics and musculoskeletal medical imaging, with particular emphasis on the relationship between mechanical factors and disease processes like osteoarthritis and osteoporosis. His work integrates mechanical testing, finite element analyses, kinematic/kinetic motion analyses, and advanced imaging techniques (CT, MRI, synchrotron radiography) to investigate joint mechanics, particularly in the hip, knee, and spine. His research has contributed to the development of novel implant designs for joint replacement.

Analysis of his publication record shows a consistent focus on bone mechanics, with particular attention to subchondral bone properties in osteoarthritis, finite element modeling of joint mechanics, and the relationship between physical activity and bone development. His work bridges engineering principles with clinical orthopaedic applications, demonstrating strong interdisciplinary collaboration with medical researchers.

Johnston has established significant research collaborations across multiple institutions, particularly with researchers at the University of British Columbia and within the University of Saskatchewan's medical departments. His work has been cited over 2,800 times with an h-index of 29, indicating substantial impact in his field.

He maintains active research in the biomechanics of musculoskeletal disorders, with particular focus on understanding the mechanical factors contributing to osteoarthritis development and progression, as well as developing engineering solutions for joint replacement and rehabilitation. His laboratory work involves both computational modeling and experimental biomechanical testing.
