Current Research Activities

Triacylglycerol (TG, also commonly referred to as fat) is the most concentrated form of energy storage in humans. Excessive TG storage is manifested as obesity, which is a major health problem in the Western world. Obesity is a risk factor for hypertension, diabetes and cardiovascular disease. Therefore, there is a substantial pharmaceutical interest in the enzymes that control TG metabolism in tissues. Our research is focused at elucidating the mechanism by which TG is utilized in the liver, intestine, adipose and other tissues.

Biography

 

Dr. Lehner obtained his PhD in Biochemistry at the University of Toronto, followed by post-doctoral training at the CNRS in Marseille, France and at the University of Alberta. He joined the Department of Pediatrics at the University of Alberta as an Assistant Professor in 1998 with cross-appointment in the Dept. of Cell Biology. In 2008 Dr. Lehner was appointed Director of the Group on Molecular and Cell Biology of Lipids.
