Our research goals are:
- To understand the physiological importance of local DPP4 activity and substrate cleavage in the setting of diabetes and cardiovascular disease.
- To understand the cellular-sites of DPP4 important for regulation of glucose and lipid metabolism.
- To understand how the gut adapts to food ingestion.
