Research interests: functional foods; the metabolic syndrome; biomarkers; children and adults; dietary supplements; athletes, non-athletes and exercisers

Area: Clinical Nutrition; Sports Nutrition (Applied Human Nutrition)

Description of research: Dr. El Khoury’s research interests lie in the areas of 1) exploring new biomarkers for the metabolic syndrome, and their modulation by functional foods and/or physical activity, both in pediatric and adult populations; and 2) investigating the prevalence and psychosocial determinants of dietary supplement use among university athlete and non-athlete students, gym exercisers and other populations at risk.

Accepting graduate students:

Fall 2019: Yes

Winter 2020: Yes

Fall 2020: Yes 

Dr. Dalia El Khoury’s research interests focused on the role of functional ingredients/foods in the regulation of appetite, food intake, glycemia and metabolism in healthy individuals and individuals at risk for or with nutrition-related disorders including obesity and the metabolic syndrome. Dr. El Khoury has also worked in the fields of sports nutrition and infant nutrition through experiences in both academia and private industry. Dr. El Khoury is still interested in exploring additional biomarkers with respect to the metabolic syndrome, and how to manage them through dietary and/or physical activity interventions. Also, she is interested in investigating the use of dietary and sports supplements and related psychosocial determinants among different sectors of the Canadian population.

What are the qualities of a student who would be successful in your lab?

  • A love for both qualitative and quantitative research is a strength for my students. A successful student on my research team has strong interest in clinical nutrition, whether from disease prevention and treatment perspectives or from a sports nutrition approach.

How would you describe your mentoring style? 

  • I work very closely with my students, and enjoy meeting with them on weekly basis to get updates on their research projects, answer any questions they may have, work together to address any existing challenges, and revise our work plans if needed. I trust though that my students can perform their daily work very well, at their own pace, without the need to micro-manage them.

Is there anything else you’d like your potential students to know? (include things like opportunities for funding/conferences/publication etc.)

  • I will always encourage my students to attend and/or present their work at annual nutrition-related conferences, such as Canadian Nutrition Society, Experimental Biology and others. Conferences give them the opportunity to communicate their findings to the research communities, as well as to build a strong professional and research network in the nutrition field. I also strongly support students, both graduate and undergraduate, publishing their work in peer-reviewed journals.
