Dr. Peter B. Stathopulos completed his B.Sc. at the University of Waterloo in Co-operative Biology. He later graduated with an M.Sc. from the University of Western Ontario in Pharmacology and Toxicology. His Ph.D. work at the University of Waterloo was in Biology, co-supervised through the Departments of Chemistry and Physics. He completed his Post-doctoral training in Structural Biology at the University of Toronto (Medical Biophysics) and at the Ontario Cancer Centre.

Our laboratory aims to apply structural biology approaches to revealing the molecular mechanisms driving calcium signaling processes in health and diseased states including heart disease, cancer and immunodeficiency. We integrate structural biology with a host of biophysical, chemical biology and live cell methodologies in an effort to understand the relationship between structure and function of critical calcium signaling proteins. Ultimately, we use this structure-function data for the rational identification of new drug binding targets with the potential to modulate these pathways, maintain health and treat disease.
