Peter Ronner

Peter Ronner, PhD, is a Professor and Vice Chair for Education in the Department of Biochemistry & Molecular Biology at the College of Life Sciences. His primary research investigates the mechanisms regulating insulin and glucagon secretion from pancreatic cells, with a current emphasis on ATP-sensitive potassium channels (K_ATP) in glucagon-secreting A-cells. He employs advanced methodologies including electrophysiology, flow cytometry, immunohistochemistry, and custom-developed luminometric microhistochemical assays.

His laboratory studies span normal and tumoral endocrine cells, building on prior work examining Ca²⁺,Mg²⁺-ATPase in human erythrocytes and hormone dynamics in teleost fish pancreatic systems. Research interests focus on:

• K_ATP channel pharmacology in pancreatic islet cells
• Real-time monitoring of adenosine phosphates (ATP/ADP/AMP)
• Interspecies comparative endocrinology
