Dr. Adeli is the Head of Clinical Biochemistry in the Department of Paediatric Laboratory Medicine, as well as a Senior Scientist in the Molecular Medicine Program of the Research Institute, at the Hospital for Sick Children. He is also a Full Professor and Vice Chair of Quality in the Department of Laboratory Medicine and Pathobiology at the University of Toronto. He currently serves as the President of the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC), a worldwide organization with 90 member countries and more than 45,000 laboratory physicians and scientists around the world. He is also the current Editor-in-Chief of Critical Reviews in Clinical Laboratory Sciences.

Since 1988, Dr. Adeli has been actively involved in both molecular and clinical laboratory research. He has over 30  years’ experience in clinical chemistry service, education, and research, with over 600 articles and abstracts published to date. His achievements have been recognized through several distinctions and careers awards (see Publications and Awards below).

Research Synopsis

The Adeli Lab’s basic research program aims to elucidate the cellular, molecular, and physiological regulation and hepatic lipoprotein production in normal and insulin-resistant states. In recent years, the incidence of insulin-resistant states such as obesity and type 2 diabetes have been increasing at an alarming in both pediatric and adult populations. These conditions represent major risk factors for atherosclerotic cardiovascular disease, largely due to lipid and lipoprotein abnormalities. The key mechanism underlying this metabolic dyslipidemia is hepatic and intestinal overproduction of atherogenic lipoproteins. Currently, the laboratory is investigating the neuroendocrine mechanisms regulating intestinal and hepatic lipoprotein overproduction in insulin-resistant states and the role of the gut-brain-liver axis in lipid and lipoprotein metabolism

Aside from basic research, the Adeli Lab also conducts various clinical research projects. This includes the CALIPER (Canadian Laboratory Initiative on Pediatric Reference Intervals) program, which aims to establish a comprehensive database of reference or “normal” ranges for medical laboratory tests in children and adolescents. The CALIPER database, which now contains reference intervals for hundreds of laboratory biomarkers, is used by thousands of institutions across Canada and around the world to improve clinical assessment, diagnosis, and monitoring of children with medical concerns.
