My primary area of research is in the mechanisms underlying spinal disorders and the influence of manual and exercise therapies on both spinal function and clinical outcomes in persons with spine pain. This research involves the investigation of how paraspinal muscle performance and spinal motion are altered in association with spinal disorders, as well as how various manual and exercise interventions alter muscle performance and spinal motion.
