Energy Substrate Metabolism Research Laboratory

Our research goals are to understand:

  1. The physiological importance of local DPP4 activity and substrate cleavage in the setting of diabetes and cardiovascular disease.
  2.  The cellular sites of DPP4 important for regulation of glucose and lipid metabolism.
  3. How the gut adapts to food ingestion.
