Read more about my interests in research.

My general interests are related to the regulation of skeletal muscle carbohydrate metabolism in the context of muscle contraction/exercise, hormone action and disease.

Specifically I have focused on the regulation of glycogen breakdown, glycogen synthesis and glucose transport in various experimental models ranging from muscle cell cultures, and isolated rodent muscle preparations to intact humans.

This work also impacts on our understanding of insulin action in skeletal muscle and how this relates to the development of type 2 diabetes.

Current projects

  1. Use of muscle contractile properties to identify individuals exhibiting insulin resistance
  2. Role of muscle fiber composition in development of lipid-mediated insulin resistance
  3. Role of myokines in enhancing glucose-stimulated insulin secretion
  4. Methods to maximize analyses of muscle analytes in small biopsy samples.
