Professor Imbeault focuses on the impact of external influences such as exercise, nutritional interventions, hypoxia, and pollutants on adipose tissue metabolism. His research seeks to understand the pathophysiology, treatment, and prevention of obesity-related metabolic disorders. He is a member of Obesity Canada and Institut du savoir Montfort, and engages in thesis supervision requests. His team's research program aims to understand the regulation of growth and the secretory function of adipose tissue through an integrative approach at cellular and molecular levels. Recognizing white adipose tissue as a key energy reserve storage site, his team studies how intrinsic oxygen availability, or hypoxia, affects its metabolism and secretory functions. They aim to uncover how humans' cellular and systemic responses to natural environmental stress and pathological conditions, such as sleep apnea, can lead to oxygen deprivation. Additionally, the impact of persistent organic pollutants (POPs), which are synthetic chemicals resistant to natural degradation, are examined in relation to their accumulation in adipose tissue and the established link to obesity and Type 2 diabetes.
