Véronic got her first taste of research as an honours student in biochemistry at the University of Ottawa.  She worked with Dr. Mary-Ellen Harper, elucidating the role of uncoupling protein 3 (UCP3) in skeletal muscle.  Using UPC3 overexpressing and ablated mice, Véronic`s findings supported a role for UCP3 in fatty acid metabolism.

Véronic moved to Guelph to pursue an NSERC-funded doctorate in Human Health and Nutritional Sciences with Dr. Lawrence Spriet.  Her research focused on fatty acid transport across the cellular and mitochondrial membranes of human skeletal muscle.  She worked primarily with healthy and obese human subjects.  Using muscle biopsies, she explored fatty acid fates under various nutritional and exercise conditions.  Upon completion of her doctorate, Véronic returned to her home in Ottawa for a short post-doctoral fellowship with her former honours supervisor, Dr. Mary-Ellen Harper.  She had to opportunity to apply her skills in fatty acid transport and metabolism to several projects relating to UCP3.

With funding from NSERC, Véronic moved to Toulouse, France to pursue a two year postdoctoral fellowship.  Her focus shifted from skeletal muscle to adipose tissue.  Using primary adipocytes and a unique adipocyte cell line, Véronic continued her work on fatty acid fates by examining the roles of lipases in lipolysis.  Using gene silencing and adenoviral transduction approaches, Véronic`s findings identified adipose triglyceride lipase (ATGL) and its coactivator CGI-48 as essential to human adipose tissue lipolysis.

Upon her return to Canada, Véronic joined the Chemical Evaluation group at the Canadian Food Inspection Agency.  She used her biochemical research skills to gather and evaluate the literature pertaining to prevalence, toxicity, and levels of chemical contaminants in food.  She participated to the design and development of sampling plans relating to novel food-chemical hazard combinations.  She analyzed data from targeted surveys, identified trends and made recommendations to senior management with regards to regulatory guidelines of chemical food safety issues.

In July 2010, Véronic was hired by the Chemistry department at Carleton University as an Instructor in the Food Science and Nutrition program where she teaches courses in Chemistry and in Food Science and Nutrition.
