My basic interest is determining in how the body works combining mechanics and control, and consequently, how it gets injured. My research aims to determine the mechanisms of work-related musculoskeletal disorders of the upper extremity from the fingers to the shoulder (and occasionally some other parts). These disorders tend to occur over a long period of time through complex pathways. By developing a solid link between control and mechanics, we can define the mechanisms of disorders such that they can be better rehabilitated and, ultimately, prevented. We examine disorders of muscle tissue (e.g. myalgia), connective tissue (e.g. tendinitis, epicondylitis), and peripheral nerve (e.g. carpal tunnel syndrome). To reach these research objectives, we use both basic (laboratory) and applied (laboratory and field) studies. My research tools include ultrasound, MRI, tissue measurement, computer modeling, electromyography (surface and fine wire EMG), various dynamometers, data trackers, and motion analysis.
