Research summary
Physical activity; bone and body composition assessment in children and adults


Currently, I'm the Director of the Bone and Body Composition Research Unit which undertakes innovative prospective studies evaluating bone density and quantifying body composition and regional body fat distribution in children and adults using dual energy x-ray absorptiometry (DXA).

I'm also involved with three major research projects in collaboration with other members of the Edgar Diabetes and Obesity Research Centre: MInT, PLAY and Healthy Homework in several capacities, including providing physical activity recommendations for children and families and analysis and management of accelerometry for physical activity and sleep assessment.
