Research activities:
- Theoretical investigations of human pancreatic beta-cells: heterogeneous and non-intuitive electrophysiological responses to ion channel antagonists; slow oscillations due to glycolytic oscillations; paracrine signals; gap junction coupling
- Modeling of pancreatic alpha-cells: simulations of electrical activity; micro-RNA mediated effects on electrophysiology and exocytosis; glucose-sensing mechanisms including the roles of SGLT2 and K(ATP)-channels; cAMP-mediated effects downstream of electrical activity
- Intestinal L-cells: glucose sensing converging at electrical activity; spatial modeling of glucose handling, electrical activity, Ca2+ dynamics and GLP-1 secretion.
