She completed a Ph.D. in psychology in which she explored the psychosocial aspects of early retirement, using primarily the theories of relative deprivation and social identity. For nearly 20 years, she has worked on age-based prejudices, specifically the ins and outs of ageist stereotypes and discrimination. She has conducted numerous studies on the subject, particularly with older workers, retirees and older patients, both in Canada and internationally. In addition to publishing several scientific papers, she has edited two collective works on the topic of ageism: L'âgisme : comprendre et changer le regard social sur le vieillissement (2010) and Représentations et discours sur le vieillissement : La face cachée de l'âgisme? (2015).
