Research and Professional Interests

Prof. Jan is Director of Rehabilitation Engineering Lab in the Division of Disability Resources and Educational Services. He is committed to developing rehabilitation technologies for the prevention and management of secondary conditions in people with impaired mobility. He is recognized for research in microvascular dynamics and soft tissue biomechanics and their roles in the development of pressure ulcers, one of the most significant secondary conditions in wheelchair users. Prof. Jan has extensively published his research work to improve the understanding of the effect of various pathophysiological conditions (spinal cord injury, aging, diabetes, physical inactivity) on microvascular dysfunction and how this impairment contributes to the development of pressure ulcers. His pioneering work on using linear wavelet and nonlinear complexity analyses to characterize blood flow oscillations has been awarded research grants from the NIH, NIDRR, PVA Foundation and Reeve Foundation. Based on Prof. Jan’s findings, patterns of blood flow oscillations have a great potential to assess the risk of pressure ulcers and evaluate the efficacy of various preventive interventions in people with impaired mobility, including people with spinal cord injury, people with lower limb amputation, diabetics and elderly wheelchair users.


KIN 494 Rehabilitation Biomechanics (Fall): This course has been designed for students who are interested in pursuing a career in either biomechanics, physical therapy, occupational therapy, or rehabilitation engineering. Primary topic areas will include muscle biomechanics, soft tissue biomechanics, orthopedic biomechanics, prosthetics and orthotics, electromyography, bioinstrumentation, biosignal analysis and human movement science (kinematics, kinetics, energy and power).

REHB 501 Rehabilitation Research (Fall): This course will cover major topics of research design and methods used in rehabilitation and disability research. In-depth discussions of global initiatives on disability research and advocacy (WHO and UN) and disability rights will be provided. A review of human subject research, grantsmanship and scientific writing will also be covered.

REHB 594 Advances in Rehabilitation Technology (Spring): This course has been designed for students who are interested in the use of technology to solve problems faced by people with disabilities. A review of current research and development in the fields of assistive devices and technologies will be covered. Students will be required to actively participate in discussions on how technology can help improve rehabilitative process and quality of life in people with disabilities.
