I am interested in investigating the following in families with young children.  Do any of these topics catch your eye?  If so, please email me!

  • Intake of ultra-processed foods and cardiometabolic risk in children (Guelph Family Health Study)
  • How clusters of lifestyle behaviours (sleep, diet quality, total physical activity, etc.) are associated with body composition in children (Guelph Family Health Study and Family Stress Study)
  • Fat mass index (FMI) and cardiometabolic health of preschoolers (Guelph Family Health Study)
  • I am also interested in associations between lifestyle habits and fat-free mass index (FFMI) in children (Guelph Family Health Study).  Got an idea to explore this?  Reach out!
