Introduction
My research interest is the rehabilitation and exercise of individuals with cardiopulmonary impairments and physical function limitations. This research area, therefore, aims to highlight the disability present in such individuals and create and test the effect of low-cost treatment interventions as a means of reducing long-term disability. Due to being an academic and lecturer, some of my research projects and publications are about teaching and learning.
