My research interests focus on skeletal muscle carbohydrate metabolism and how it is regulated in various different states; such as muscle contraction/exercise, hormonal regulation and disease states.

In my early career (PhD) I focused on the influence of changing microvascular blood flow on skeletal muscle metabolism and its role in insulin action and T2D, in both human and rodents. Later as a postdoc I moved into exercise physiology focused work investigating the regulation of glycogen breakdown, glycogen synthesis and glucose transport in isolated rodent muscle preparations.

Since moving to GIH I have focused on human based studies looking again at the importance of muscle carbohydrate metabolism, specifically determining the role of skeletal muscle fiber type in insulin sensitivity to greater understand insulin action in muscle and how this relates to the development of type 2 diabetes.
