Graduate Student

Maria is a second year PhD student in the School and Clinical Child Psychology (SCCP) program. She is interested in examining risk and protective factors for NSSI longitudinally. Her current research focuses on the impact of traumatic experiences on NSSI engagement, and the pathways through which experiences of trauma may lead to NSSI engagement (e.g. post-traumatic stress symptoms and cognitions). Maria is a clinician-in-training interested in ways to facilitate positive mental health and well-being among children, adolescents, and emerging adults navigating stressful life experiences. Maria has completed a practicum placement at the Toronto Catholic District School Board, and is currently on practicum placement at the SickKids Centre for Community Mental Health.

Ariana Simone

Ariana Simone

Graduate Student

Ariana is a third year PhD student in the School and Clinical Child Psychology (SCCP) program. Her research interests include the disclosure of NSSI to informal (e.g., peers, parents) and formal (e.g., teachers, mental health practitioners) sources. Ariana is interested in the barriers and facilitators of disclosures, as well as the predictors and outcomes of NSSI disclosures. Ultimately, Ariana hopes to understand how to make NSSI disclosures more positive, helpful, and safe from a clinical perspective. As a clinician-in-training, Ariana is interested in how early life experiences and relationships with caregivers impact current functioning in children, adolescents, and emerging adults. She has undergone practicum placements within the Toronto Catholic District School Board and the SickKids Centre for Community Mental Health, and is currently completing a practicum placement at Kinark Child and Family Services.
