Frédérique Tesson

Frédérique Tesson is a molecular geneticist and professor. She teaches in the Interdisciplinary School of Health Sciences in the Faculty of Health Sciences and is cross appointed to the Faculty of Medicine. Before joining the Faculty of Health Sciences in 2009, she worked at the University of Ottawa Heart Institute and at the Hôpital de la Pitié-Salpêtrière in Paris. She also studied and completed her PhD of sciences in Paris.

She is a member of the evaluation committee for CIHR and the Fonds de la recherche en Santé du Québec.

Her research is focused on the contribution of the genome in the development of heart disease, as well as the analysis of the interactions between the genome and the environment as risk factors for cardiovascular illnesses. Presently her research, conducted in collaboration with Canadian and international researchers and clinicians, relates to the following:

• the study of genetic and molecular mechanisms that lead to heart failure,
• the study of genetic and molecular mechanisms involved in weight loss due to poor calorie intake or an exercise program,
• the study of the contribution of the genome in high-blood pressure linked to sodium consumption.

Her lab is located near the University of Ottawa’s Roger Guindon Hall. Her team comprises a research co-ordinator (who spearheads the recruitment campaigns for patients and their families), a lab technician, postdoctoral fellows, as well as students from both undergraduate and graduate levels. Her research is funded by the Canadian Institutes of Health Research (CIHR), the Heart and Stroke Foundation and the University of Ottawa.
