​About our research

We are interested in pancreatic islet function in health and diabetes. Our research has spanned areas that include biophysical characterization of ion channels, intracellular signal transduction and exocytosis, and the cellular regulation of glucagon secretion. With wonderful international collaborators, some exciting new directions include islet-cell phenotyping by combined patch-clamp and single-cell sequencing; and computational modelling of human islet cell profiles. We are interested in anything that impacts islet function and hormone secretion!

Our techniques are mostly cell-based and include hormone secretion assays single cell patch-clamp electrophysiology, and cellular imaging applied to human islets and transgenic animal models.
