Constantine Tsigos

Constantine Tsigos is Professor of Human Nutrition and Metabolism at Harokopio University of Athens. He holds an M.D. (summa cum laude) from the University of Athens and a Ph.D. from the University of Manchester, with board certification in Endocrinology, Diabetes, and Metabolism. His professional experience includes roles as Senior Research Fellow and Attending Physician at the National Institutes of Health (NIH) in the United States and as Director of Basic Research at the Hellenic National Diabetes Centre.

Research Focus: Dr. Tsigos investigates diabetes/obesity pathogenesis, stress-related metabolic complications, inflammatory cytokine effects on endocrine axes, and hormone resistance mechanisms. His work bridges clinical medicine and molecular biology, particularly in metabolic disorders and neuroendocrine regulation.

Publications: His research output spans three decades with consistent focus on metabolic physiology, endocrine disorders, and obesity management. Recent publications emphasize clinical guidelines and molecular mechanisms in diabetes/obesity, while earlier work established foundational insights into stress physiology and hormone receptor genetics.
