My research focuses on social determinants of health, qualitative and participatory methodologies in community health research, and theoretical contributions in a social change based approach to health promotion. Most recently, I have focused on the socio-environmental determinants of the obesity epidemic, and community-based strategies to promote healthy weights at multiple ecological levels. I am one of few researchers in Canada with the experience and expertise in the area of nutrition policy and policy advocacy. Current projects include the Alberta Policy Coalition for Cancer Prevention, which includes an interdisciplinary, intersectoral team examining the efficacy of the Coalition as the mechanism for increasing capacity to develop sustainable system change to catalyze policy development, adoption, implementation, and evaluation to tackle behavioural correlates of cancer incidence, in particular, poor nutrition and physical inactivity. A major focus of this work will be policy change within schools to support healthy lifestyle behaviours among children.
