    Shawn C. Roll received his B.S. in Occupational Therapy from The Ohio State University, graduating magna cum laude with distinction. He continued his post-secondary education at OSU, obtaining an M.S. in Allied Health Professions with a Minor in Research Methods in Human Resources Development, and received his Ph.D. degree in Health and Rehabilitation Sciences with an Interdisciplinary Specialization in College and University Teaching. Dr. Roll's clinical experience is in work programs, focusing on assessment, prevention and rehabilitation of work-related injuries. Dr. Roll is a registered and licensed occupational therapist (OTR/L) and a registered musculoskeletal sonographer (RMSKS).

    Dr. Roll has developed an interdisciplinary research career combining his clinical occupational therapy skills with specialization in musculoskeletal sonography and industrial engineering/ergonomics. Through his research, he collaborates with rehabilitation providers, radiologic sciences, industrial and systems engineering, neurology and orthopedics. Dr. Roll's research strives to advance the understanding of musculoskeletal disorders through a holistic approach, to effectively evaluate and provide prevention or rehabilitation interventions within the adult population. His research focus includes:

    1. Use of diagnostic sonography in the evaluation, prevention and treatment of musculoskeletal disorders with a primary focus on the upper extremities

    2. Investigation of physical exposures, stress, psychosocial factors and personality traits as each relate to the development of musculoskeletal disorders and how each mitigate or promote successful prevention and rehabilitation efforts

    3. Investigation of tools and approaches for determining functional capacity in healthy and injured workers
