Brief Biography

Dr. Finkelstein is a Professor of Pediatrics, Pharmacology and Toxicology, University of Toronto, and a staff physician, The Hospital for Sick Children, Toronto. He graduated from Sackler School of Medicine, Tel Aviv, Israel with thesis honors and completed pediatrics residency at Schneider Children’s Medical Center, where he then served as Associate Department Chief. Following Medical Toxicology training at the Chicago Toxikon, University of Illinois (2002) and a fellowship in Pediatric Clinical Pharmacology and Toxicology (2004-2007) and Emergency Medicine at the Hospital for Sick Children he joined on hospital staff. He is board-certified in Clinical Pharmacology (American Board of Clinical Pharmacology, 2007), and is an appointed Senior Associate Scientist in the Research Institute (Child Health Evaluative Sciences). Between 2008-2010, he was appointed an adjunct/visiting Associate Professor at Harvard Medical School, Boston.

Dr. Finkelstein’s main research focus is in pediatric therapeutics in acute-care settings. His long-term goal is optimization of drug safety, especially of highly toxic drugs and poisoning management and prevention in children. Using cutting-edge methodologies in pharmacogenetics, pharmacometrics, adverse drug-reaction analysis, translational research and epidemiological/toxico-surveillance tools he strives to enhance effective and safe drug delivery to children with an emphasis on emergency settings. Dr. Finkelstein has also made significant contributions to the understanding and prevention of pediatric poisonings, accidental and deliberate.

Dr. Finkelstein has published over 100 original and review articles in peer-reviewed journals, as well as book chapters in leading medical textbooks; he sits on scientific journals’ editorial boards and has an active role in various professional societies, such as the American College of Medical Toxicology. Dr. Finkelstein holds international scientific awards, and his research program is supported by local and international grants.
