Natalie Castellanos-Ryan est chercheuse au CHU Sainte-Justine de Montréal et professeure adjointe à l'École de psychoéducation, Université de Montréal. Auparavant, elle était stagiaire postdoctorale au Centre de recherche du CHU Sainte-Justine et au Département de psychiatrie, Université de Montréal (2010-2014). Elle a complété son doctorat à l'Institut de psychiatrie, King’s College London (2009), où une grande partie de son travail était centré sur la mise en œuvre et l'évaluation d'une approche ciblant les facteurs de risque de la personnalité pour la prévention ou l’intervention précoce de la consommation de drogues et d'autres problèmes de comportement à l'adolescence.

Actuellement, ses recherches portent sur:

1. Le développement des psychopathologies et les analyses longitudinales;
2. L'étude de la variance commune et des facteurs de risque partagés entre les troubles de santé mentale, en particulier les troubles extériorisés;
3. Leur prévention.

Plus particulièrement, ses intérêts de recherche comprennent comment les déficits d'autorégulation, ainsi que le développement pubertaire et cognitif prédisent les problèmes de toxicomanie et la comorbidité psychopathologique chez les jeunes, et comment la personnalité et les facteurs environnementaux sont impliqués dans ces associations.
