Chaoran Dong, PhD Student
Supervisor: Dr. Petros Pechlivanoglou, Senior Scientist, The Hospital for Sick Children and Associate Professor, Institute for Health Policy Management and Evaluation University of Toronto
Project Title: The Value of Reducing Geographical Disparities in Access to Pediatric Cancer Care in Ontario
Award Year: 2023
Read Chaoran's Bio
Chaoran Dong is a PhD student in the Health Technology Assessment Stream at the Institute of Health Policy, Management and Evaluation, University of Toronto. Her research interests primarily focus on economic evaluations in serving vulnerable populations, particularly with respect to priority setting and resource allocation in the healthcare system. Her project aims to 1) assess the economic impact of reducing geographical disparities in pediatric cancer care access through the current provincial program for households with varying socioeconomic status, and 2) to guide future expansion of the program or/and adoption of the program from different provinces. The results of this project will help understand the value of improving geographic accessibility for pediatric cancer patients in Ontario , which will address knowledge gaps in the current studies.

Project Title: The Intersection of Social Disparity, Neonatal Hippocampal Development, and Cognition in Infants with Congenital Heart Disease
Award Year: 2023
Read Pearl's Bio
Dr. Pearl Zaki is a second year Paediatric Neurology resident at the University of Toronto. She completed medical school at the University of Toronto and her undergraduate studies at the University of Waterloo in Health Studies.

Sabrina Chiodo, PhD Candidate
Supervisor: Dr. Laura Rosella, Professor and Canada Research Chair in Population Health Analytics, Dalla Lana School of Public Health, University of Toronto
Project Title: Predicting and Preventing Adverse Pregnancy Outcomes: Integrating Clinical, Social, and Environmental Factors into Population Risk Models
Award Year: 2025
Read Sabrina's Bio
Sabrina is a PhD candidate in Epidemiology at the Dalla Lana School of Public Health, University of Toronto. Her research leverages predictive modelling techniques and population-level data to improve maternal and child health outcomes across Canada.

Drawing on linked national survey and administrative health data, the project seeks to identify individuals at high risk for conditions such as preeclampsia, gestational diabetes, and placental abruption. The tool will be used to estimate the burden of APOs across different populations and simulate the impact of public health interventions designed to address health inequities.

Natasha Bruno, PhD Student
Supervisor: Dr. Eyal Cohen, Senior Scientist and Program Head of the Child Health Evaluative Sciences & Co-Director of the Edwin S.H. Leong Centre for Healthy Children, SickKids
Project Title: Bridging Gaps in Care: Using Social Network Analysis to Explore the Evolution of HealthCare Networks During Transition to the Adult System for Youth with Medical Complexity
Award Year: 2025
Read Natasha's Bio
Natasha Bruno is a PhD student studying Health Systems Research at the University of Toronto’s Institute of Health Policy, Management and Evaluation. Utilizing a retrospective cohort study design, her project will explore how health care networks for youth with medical complexity (YMC) evolve as they transition from paediatric to adult health systems. Leveraging social network analysis and health administrative data, she aims to (1) describe the structure of YMC’s health care networks pre-transition, (2) compare the structure of YMC’s health care networks over time, and (3) assess whether the structure of YMC’s health care networks during transition influence acute care use and mortality post-transition. Insights gained from this research will inform actionable recommendations to enhance continuity of care, strengthen system navigation supports, and address disparities in service access for YMC. This work represents one of the first applications of social network analysis to study the transition from paediatric to adult care and will help inform more integrated, data-driven strategies to support YMC navigating this critical period.

Award Year: 2025
Read Emily's Bio
Emily Hamovitch is a PhD candidate in the Institute of Health Policy, Management & Evaluation. Her project will use an equity lens to examine predictors of follow-up services for children and youth who have been discharged from psychiatric hospitalization.
