I am interested in the regulation of integrated physiological responses and muscle metabolism during physical activity and dietary manipulations. My current work is focused on the impact of alterations in muscle cell volume on the regulation of muscle metabolism and muscle hypertrophy and atrophy. I am also interested in the effects of dietary supplementation of various compounds, including dairy products, on muscle and bone metabolism in healthy, diseased, and ageing populations. I am also currently investigating dietary interventions for the treatment and reduction in severity of sport induced concusssions.
