In the past year, George worked with Dr Mirisse Foroughe at the Family Psychology Centre in downtown Toronto, examining adaptations of Emotion Focused Therapies using parent-infant dyad interventions to both treat current trauma symptoms, as well as prevent future intergenerational carryover of traumatic effects in youth.

Currently supervised by Dr Robert T. Muller in the Trauma and Attachment Lab, Marlee’s work has shifted to evaluating attachment-based therapeutic interventions for families with trauma histories, with the goal of promoting effective mental health services particularly through the caregiver-child relationship.
