Pierrich Plusquellec’s work relates to measurement of biological and psychological stress and nonverbal behavior in adolescents from Nunavik, as well as the association between exposure to pollutants and biological stress in a sample of elderly.

He also assesses the effects of:

  • The DeStress for Success program in adolescents with behavioral disorders and
  • Stress and Company© program in Stakeholders in Centres Jeunesse in Montreal –Institute universitaire, which represent a population with a high-risk profile of burnout.
This program allows a customized prevention of disorders associated with chronic stress. It also assesses the effects of mobile application named iSMART among workers at the Institut universitaire en santé mentale de Montréal which allows customization of methods to detect and resolve chronic stress. Finally he is looking for behavioral markers of stress from the analysis of nonverbal behavior in psychosocial stress situation in young adults. He is Co-Director of the Centre for Studies on Human Stress (CESH).
