About Daniel J. Drucker
Daniel Joshua Drucker (born 23 June 1956) is a Canadian endocrinologist renowned for his breakthrough discoveries of the biological actions of glucagon-like peptides GLP-1 and GLP-2, including GLP-1's key role in stimulating glucose-dependent insulin secretion, reducing food intake, protecting the heart, and reducing systemic inflammation. His scientific research has been a driving force in GLP-1's journey from a newly discovered peptide sequence to the mechanism behind globally used and life-changing therapeutics for type 2 diabetes and obesity. It has also driven transformative new therapeutics for intestinal failure and other metabolic disorders. A Fellow of the Royal Society, and laureate of the 2023 Wolf Prize in Medicine, he is a University Professor of Medicine at the University of Toronto and Senior Investigator at the Lunenfeld-Tanenbaum Research Institute, Sinai Health, Toronto. == Early life and education == Drucker was born and grew up in Montreal, went to high school in Ottawa, and then enrolled at the University of Ottawa, studying science. In 1976, he moved to Toronto, where he studied medicine at the University of Toronto, graduating in 1980. He completed his internship at Johns Hopkins Hospital (1980–81) and completed his internal medicine and endocrinology residencies at the University of Toronto (1981–84). == Career and research == In 1984, Drucker began his research career at Massachusetts General Hospital and Harvard Medical School, studying molecular endocrinology in the lab of Professor Joel Habener with the support from a Medical Research Council of Canada Centennial Fellowship. Drucker’s independent discoveries in Boston included the demonstration that proglucagon could be cleaved into multiple glucagon-like peptides, including several distinct isoforms of GLP-1. He then discovered that the truncated form of GLP-1(7-37) directly stimulated cyclic AMP formation, insulin secretion, and insulin gene expression; notably, it did so only when glucose levels were elevated.
