Research Interests
My research interests lie mainly in the area of health psychology, and at the overlap with social and developmental psychology. Broadly speaking, I am interested in the impact of stress and trauma on psychological and physiological health.
My research predominantly focused on the impact of stress on the health of adolescents and young adults, and explored how our social relationships, social support, attachment bonds and group memberships an alleviate the damaging effect of stress on health.
Teaching Interests
My teaching interests incorporate research methods and statistics (undergraduate and postgraduate), introductory psychology (Psychology and Everyday Life, Psychology and Social Issues), and health and developmental psychology.
