Principal Investigators

Executive Committee

Melanie Henderson

Melanie Henderson is a pediatric endocrinologist, affiliated with CHU Sainte-Justine. She has a PhD in epidemiology at McGill University. Her research focuses on the risk factors for the development of type 2 diabetes mellitus in children, as well as the prevention and treatment of obesity in youth.  Since 2012, she took over as the investigator in charge for the QUALITY cohort. In 2013, she became co-director of CIRCUIT (Centre pédiatrique d'intervention en prévention et en réadaptation cardiovasculaires).

 


Gilles Paradis 

Gilles Paradis is a physician specialized in community medicine and full professor in the Department of Epidemiology, Biostatistics and Occupational Health of McGill University. He is the Scientific Director of the Population Health Research Network and the Director of the Quebec Public and Population Health Research Training Program. He has conducted community-based CVD prevention research in low-income populations and aboriginal communities as well as research on the epidemiology of CVD risk factors particularly in children and adolescents. He is the principal-investigator of a large trial of dissemination of best practices for CVD prevention in Quebec and is involved in studies of the metabolic consequences of obesity in children and of the natural history of the development of nicotine addiction in novice smokers.

 


 Angelo Tremblay

Angelo Tremblay is currently professor at the Division of Kinesiology of the Department of Social and Preventive Medicine at Laval University, Quebec, from where he obtained his undergraduate (BSc in Education) and postgraduate degrees (MSc in Nutrition and PhD in Physiology) between 1974 and 1982. Dr. Tremblay's department has an international reputation in obesity research and his own particular interests are focused primarily on exercise and energy balance in humans. He is holder of a Canada Research Chair in Environment and Energy Balance.

 


 Katherine Gray Donald

Katherine Gray-Donald, PhD in Epidemiology from McGill University, is an Associate Professor in the School of Dietetics and Human Nutrition at McGill University and is the president of the Canadian Society for Nutritional Sciences. Her research focuses on improving diet and nutritional outcomes among different high risk groups in Canada, particularly children and the elderly.

 


Tracie A Barnett:  Built Environnement Study

Tracie is a researcher at Sainte-Justine Hospital and a professor in the department of  Exercise Science at Concordia University. She is an epidemiologist with training in public health and health promotion. She is interested in assessing life settings relevant to children, describing longitudinal patterns of physical activity, sedentary, and dietary behaviours, and understanding how distinct patterns are influenced by children’s built and social environments. As part of the QUALITY team, she is investigating the importance of school and neighbourhood factors in children’s cardiovascular risk profile. 

 

 


 

 Late Marie Lambert

Marie Lambert was the principal investigator of the QUALITY cohort from the beginning of the study until her death in February 2012. She played a major role in the creation and development of the QUALITY study. Dr. Lambert was a pediatrician and a geneticist at CHU Sainte-Justine, and a tenured professor in the Department of Paediatrics at University of Montréal. She has been the Director of the CHU Sainte-Justine Pediatric Lipid Clinic from 1988. The focus of her research was on identifying and understanding the genetic, biochemical, behavioural and environmental determinants of cardiovascular risk factors in children and adolescents.

 

 


 

Affiliated researchers

  


 Arnaud Chiolero

Arnaud Chiolero MD MSc PhD is an epidemiologist and public health physician. After having trained as a medical doctor (MD) at the University of Lausanne (www.unil.ch), in Switzerland, he obtained an MSc in epidemiology at the Erasmus University Rotterdam (www.nihes.nl), in the Netherlands. With a grant from the Swiss National research Fund (FNS) and as a fellow of the Canadian Institutes of Health research (CIHR), he obtained a PhD in epidemiology from McGill University in Montreal (www.mcgill.ca). It is a specialist in prevention and public health (board certificate) and senior lecturer (privat-docent) at the Institute of Social and Preventive Medicine of Lausanne (www.iumsp.ch), where he leads epidemiological research on hypertension and cardiovascular health in children. In addition, he worked as chief-physician and epidemiologist at the Observatoire valaisan de la santé in Sion (www.ovs.ch), Switzerland, where he oversees the health surveillance activities.


Belinda Nicolau: Oral Health Study  

 

Dr Nicolau obtained her degree in Dentistry from Brazil and her graduate studies were conducted at University College London-United Kingdom where she got a MSc and PhD in Epidemiology. Having completed postdoctoral training at the Faculty of Dentistry McGill University she has taken up a faculty position as Assistant Professor at INRS-Institut Armand-Frappier in spring 2005. Dr Nicolau also holds a position as an Adjunct Professor in the Faculty of Dentistry-McGill University and is a Canadian Institutes of Health Research (CIHR) New Investigator. Her research activities, funded by the CIHR and FRSQ, consist in epidemiological studies examining life course processes and exposures and their links with chronic oral disease etiology.


 

Jennifer O'Loughlin

Jennifer O'Loughlin is a Professor at the Centre de recherche du CHUM and in the Department of Social and Preventive Medicine at the Université de Montréal.  She is a Canada Research Chair in the Early Determinants of Adult Chronic Disease. Her research focuses on population-based longitudinal studies of tobacco use in youth, development and validation of methods to measure smoking and nicotine dependence in youth, and evaluation of individual, school-based, community and health professional tobacco control interventions. Her current research interests focus on investigation of genetic and socio-environmental determinants of tobacco use and nicotine dependence.

 


 

Jennifer J McGrath:  Stress Study 

Jennifer J. McGrath is an Assistant Professor, Department of Psychology, at Concordia University in Montreal. Her research focuses on the pathogenesis of subclinical cardiovascular disease markers across childhood and adolescence as mediated by potential behavioural, environmental, and psychological mechanisms. Jennifer also studies the effect of socioeconomic inequalities at the individual- and neighborhood-level on cardiovascular health behaviors (smoking, physical activity, sedentary behavior, diet) in youth. As part of the QUALITY team, her main focus is on the stress response system and how it plays a mechanistic role in the pathophysiology of metabolic syndrome and obesity.

 


  Katerina Maximova

Katerina Maximova holds a PhD in epidemiology at McGill University. Her research interests include cardiovascular health of children and adolescents, and longitudinal and cohort study designs and analytical methods. Her doctoral dissertation addresses the development of risk of obesity, blood pressure, and physical inactivity over time in youth.

 

 


 Vicky Drapeau

Vicky Drapeau holds a bacholor's degree in nutrition and a PhD in Kinesiology from Laval University. She is an associate professor in the Department of Physical Education at Laval University. She is the co-founder and coordinator of the Clinique Équilibre-Santé at Laval University (a consultation clinic in physical activity and nutrition). Her research focuses on dietary behaviours associated with weight control, the treatment and prevention of obesity, nutrition, and health education. In QUALITY study, Mrs Drapeau is interested in the etiology of night-eating syndrome and its impact on obesity and weight gain.
