In summary, my research program aims to generate new knowledge in four major areas:
When pursuing these areas, I rely on various techniques and approaches from biomedical sciences, engineering, kinesiology, physics, mathematics, medicine, rehabilitation science, psychology, and the social sciences to perform integrated, holistic analyses.
Research projects in these areas have ranged widely and all have involved student participation, from the undergraduate, MSc, and PhD levels. Some examples of work done in my lab include:
My overriding goal as a researcher is to produce new information to improve both the working and non-working lives of people throughout the world, with a particular focus on the shoulder.
