Introduction
I am an exercise and sport scientist with a strong interest in two main areas. 1. The benefits, barriers, motives and facilitators to general and therapeutic physical activity in older adults and cancer patients and survivors; 2. Understanding the acute and chronic adaptations to resistance training and skills-based training in athletic populations.
