Short Bio:

Dr. Woo is currently Professor of Medicine and Medical Biophysics at the University of Toronto, and Canada Research Chair in Diabetes Pathogenesis. She is a clinician scientist and Head of the Division of Endocrinology and Metabolism at University Health Network and Health Sinai Systems.

Dr. Woo received her MD at University of Toronto followed by training in Internal Medicine and subspecialty in Endocrinology and Metabolism at the University of Toronto. She then pursued a molecular research and completed a PhD in the Department of Immunology at University of Toronto.

Dr. Woo leads a vibrant research group of talented trainees at all levels in both MD and PhD streams and is an active member nationally in the CIHR and Canadian Diabetes Association (CDA) as well as locally as executive in the Department of Medicine at the University of Toronto. Her research is recognized in the Department as an Eaton Scholar, nationally with 2011 CDA and CSEM Young Scientist Awards, and internationally a member elect of the American Society of Clinical Investigation.

 

Major Contributions:


The major research focus in the Woo laboratory is to elucidate molecular mechanisms that determine the pathogenesis of insulin resistance and type 2 diabetes. We focus on major signal transduction pathways including PI3K and JAK-STAT in metabolic tissues that contribute to insulin resistance and diabetes using tissue specific genetic engineering techniques in mice. We investigate many of the fundamental genes that are involved in cell survival and apoptosis, as well as tumour suppressors and oncogenes, including caspases, PTEN, DJ-1 and JAK/STAT. We examine the fundamental physiological roles of these genes and pathways in metabolic tissues including the liver, muscle, adipose tissue, and the pancreatic islets to uncover the highly context dependent and tissue-specific functions. Whole body metabolism as well as biological and molecular approaches are used in primary tissues and cell lines to define mechanistic physiological and pathogenic roles. We also study the role of metabolism in cancer and cardiovascular disease. We collaborate widely both locally and internationally.
