Holly Boyne

Holly Boyne

Graduate Student

Holly is a first year PhD student in the School and Clinical Child Psychology (SCCP) program. Her research interests include longitudinal examinations of intrapersonal risk factors for NSSI, and the impact of self-beliefs on NSSI engagement (e.g. self-compassion and self-criticism). Holly’s master’s thesis examined the mechanism through which depressive symptoms and stress may heighten risk for NSSI among post-secondary students. As a clinician-in-training, Holly is interested in strengths-based, person-centered approaches to assessment and intervention with children, adolescents, and emerging adults. Holly has completed a practicum placement at the Toronto District School Board, and currently sees clients at the OISE Psychology Clinic.

Lexi Ewing

Lexi Ewing

Graduate Student

Lexi is a third year PhD student in the Developmental Psychology and Education (DPE) program. Her research broadly focuses on trajectories of psychological risk and resiliency among post-secondary students. Specifically, Lexi investigates how students cope with stressful events experienced in post-secondary settings, and the impact these coping behaviors have on students’ overall well-being. Lexi is interested in bridging the gap between research and application; she hopes to work on knowledge transfer, dissemination, and implementation activities related to mental well-being among post-secondary students. Lexi manages a variety of lab-based research projects, and has worked as a teaching assistant for two graduate-level courses. This year, Lexi is completing an internship with the Knowledge Translation team at the SickKids Learning Institute.

Maria Ilieff

Maria Ilieff

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.
