Madeleine Bird (2011-     )

Madeleine Bird is a doctoral student in Public Health, Epidemiology, with the School of Public Health of Université de Montréal. Under the direction of Drs. Geetanjali Datta and Tracie A. Barnett, her research project focuses on built and social environments and physical activity. It aims to identify the physical characteristics and policies that are favourable to physical activity in three environments: at school, at home and in the neighbourhood, from the Residential Study of QUALITY. As a starting point, she will analyse the characteristics of each of the three environments that may favour physical activity among youth. Following, she will try to identify the combination of characteristics of these three environments together that are more or less favourable to physical activity. It is expected that this project will help to develop interventions that can promote physical activity among youth. Ms. Bird finished her Master’s degree in December 2012 also under the direction of Drs. Datta and Barnett, using data from the Residential Study of QUALITY. During her Master’s, she focused on park characteristics that theoretically favour physical activity among youth.

Former students

Andrée Castonguay

Andrée Castonguay is a post-doctoral fellow in the Department of Psychology at Concordia University. As she is trained in exercise and health psychology, her research interests are centered around identifying psychological and personality factors that may increase physical activity levels and mental and physical health in at risk populations, such as cancer survivors, women, and youth. She hopes that this knowledge will help guide the development of evidence-based interventions to increase physical activity levels, as well as the well-being and health status of Canadians. As a part of the QUALITY research team, she will examine the psychosocial factors that are associated with physical activity as well as the consequences of leading a physically inactive lifestyle among youth at risk for obesity.

Perceived exertion of children of different weight status and level of physical activity.

Jennifer Brunet

Jennifer Brunet is an assistant professor at the School of Human Kinetics at the University of Ottawa. Her different research projects are focused on physical activity. Specifically, they are aimed at identifying and understanding psychosocial processes that may influence people’s physical activity motivation and behaviour in order to better inform interventions to address the health burden related to physical inactivity in Canada. As part of the QUALITY team, she is investigating interpersonal factors that are linked to physical activity among youth at risk for obesity.


 Maxime Pedneault ( 2009 -  2013 )

Sean Mark ( 2005 - 2010 )

Dr. Sean Mark has a background in molecular genetics and trained as a nutrition epidemiologist at McGill University. His doctoral work showed a high prevalence of vitamin D deficiency amongst Quebec youth. Work with the QUALITY study will examine the correlates of vitamin D status as a means to ameliorate vitamin D status in Canadian youth. Dr. Mark is currently a Senior Nutrition Advisor at First Nations Inuit Health Branch, Health Canada. In the broadest sense, our work aims to validate the health benefits of high fat diets, which were common among pre-contact First Nations and Inuit in Canada. As part of this work, we are involved in a number of research projects which aim to show the deleterious effects of sugar intake on metabolic and mental health outcomes in both youth and adults. We are also collaborating with a number of health care practices in British Columbia to evaluate weight loss programs and to provide scientific support to assist in the sustainability of such programs.  

Sophie Arpin ( July 2008 - December 2008 )
