Thierry Gagné, PhD

Research Fellow, University College London


I am a Research Fellow affiliated with the ESRC International Centre for Lifecourse Studies in Society and Health and the Department of Epidemiology and Public Health at University College London, funded by the Canadian Institutes for Health Research (CIHR) and Fonds de Recherche du Québec - Santé (FRQS).

My program of research aims to better understand the changes in mental wellbeing and cigarette smoking among young adults over time, the role of the transition to adulthood in the development of health inequalities over the life-course, and its increasing role among the new generations facing poorer economic opportunities over time.

This research is done using a wide range of datasets covering Canada, the United Kingdom, and the United States. These include in the UK the 1958 National Child Development Study, the 1970 British Cohort Study, the 1990-born Next Steps study, and the Understanding Society study.
