When I finished my undergraduate degree, I was offered an exciting opportunity to spend 6 months at the Nestlé Research Centre in Switzerland. And I found out that Nestlé does far more than just make good chocolate! Nestlé introduced me to the field of nutrigenomics. This area of research examines how the foods we eat interact with our genes to affect our health. Working in this fascinating area allowed me to integrate various scientific disciplines into my research, ranging from nutritional biochemistry and molecular biology to genomics and bioinformatics. My initial 6 month position with Nestlé ended up becoming a 6 year stay, during which I completed my PhD in association with the University of Lausanne. After finishing my PhD, I moved to The Scripps Research Institute in San Diego, USA for a short post-doctoral position and then to the Institut National de la Santé et de la Recherche Médicale (INSERM) in Paris, France for a second post-doctoral position. During my post-doctoral research I explored diet-gene interactions in the context of obesity. This proved both timely and highly relevant given the high prevalence of obesity. Obesity is a complex disease that is highly influenced by lifestyle factors such as diet and exercise. Each of these factors influences our genes and, ultimately, our health. In 2009, I joined the Department of Human Health & Nutritional Sciences to establish a nutrigenomics research program to study how dietary fats influence lipid metabolism in key metabolic tissues such as adipose and liver, and how this influences cardiometabolic outcomes.

My nutrigenomics research program investigates the mechanisms that regulate lipid metabolism in the body, with a major focus on diet-gene interactions in adipose (fat) tissue, skeletal muscle, and liver. Dysfunctional lipid metabolism is a key feature of common chronic diseases such as obesity and type 2 diabetes, as well as an underlying cause of inflammation and insulin resistance. My team aims to advance understanding of the genetic and nutritional regulation of fatty acid desaturases (key enzymes involved in endogenous fatty acid synthesis), and their association with cardiometabolic outcomes. Ongoing research in my lab uses cell and rodent models to explore how altered desaturase activity and dietary fatty acids influence cellular processes such as adipogenesis, lipogenesis, and lipolysis. Notably, our research has important implications for humans, since we and others have shown that humans with variations in desaturase genes show many of the same metabolic outcomes as our model systems in which the activity of these desaturases are inhibited.

Positions Available:

PhD Position to investigate omega-3 fatty acid regulation of the adipose tissue-liver axis (Start Date: May 1, 2022). Candidates in strong academic standing and with demonstrated experience conducting mouse studies will be given priority.

MSc Position to study the regulation of skeletal muscle function by dietary omega-3 fatty acids (Start Date: May 1, 2022). The candidate will be jointly supervised by me and Dr. David Dyck (https://www.uoguelph.ca/hhns/people/dr-david-j-dyck). Omega-3 fatty acids play important roles regulating cell signalling pathways; however, different omega-3 fats have distinct roles. The focus of this MSc position will be to advance our understanding of how different omega-3 fats influence fat and carbohydrate uptake into skeletal muscle and subsequent effects on substrate utilization. 

Candidates in strong academic standing and with prior laboratory experience will be given priority.
