Within the Nutrition, Bone and Oral Health Research Group, her team’s overall research goal is to develop dietary strategies that help protect against osteoporosis, and to also understand how diet can be used to promote periodontal health. Using advanced imaging, biomechanical strength testing and biochemical analyses the team investigates how calcium and vitamin D, as well as novel foods and food components including flaxseed and its omega-3 fatty acid, fish oil, flavonoids in tea and citrus, and soy and its isoflavones impact bone health using preclinical models. Sex-specific responses are studied within these studies. These projects are funded by major government granting agencies (NSERC, CIHR, CFI). Clinical studies investigate how diet is associated with better periodontal health and healing outcomes after periodontal procedures.

Current research interests involve humans or experimental models to investigate the following areas: 

  • The mechanisms by which foods or bioactives in foods – including flavonoids present in tea or dietary estrogens such as flaxseed lignans or soy isoflavones, or specific fatty acids – modulate bone metabolism during challenges (i.e. during pregnancy and lactation, or during aging) 
  • How foods or food components promote oral health and healing after periodontal procedures 
  • Nutritional programming: Understanding how early life diet – including soy isoflavones, folic acid, vitamin D and protein – favourably programs bone and muscle metabolism 

Knowledge Mobilization: We are actively involved in knowledge mobilization activities for health professionals and lay audiences on topics related to nutrition and bone, oral/periodontal or women’s health through oral presentations, podcasts and print media
