Yasmin Aboelzahab
Yasmin’s doctoral research explores the role of pharmacists in supporting newcomer international students as they transition to the Canadian healthcare system. Yasmin’s research also investigates the use of virtual care as a flexible, accessible, and scalable approach to raise awareness and provide health-related knowledge to international students. Her previous research explored decreasing psychological stress associated with the recent diagnosis of Parkinson’s disease.

Antonia Maria Di Castri
Antonia’s doctoral dissertation looks critically at public health approaches to preventing tick-borne diseases using more-than-human theories of health rooted in epistemic, social and ecological justice. Her previous research has been in the areas of social and behavioural vaccinology looking at issues of access, consent, trust, healthcare professional culture, (mis/dis)information and vaccine policy.

Aden Fisher
Aden’s doctoral research focuses on the implications of a health-supporting food system on dietary transitions and cultural food within the context of the climate crisis. His previous research focused on the relationship between youth food-climate activists and the City of Toronto as part of the Youth Climate Action in Toronto project partnership.

Sarah Jarvis
Sarah’s doctoral research examines human nutrition and dietary patterns at the intersection of population and planetary health, and tools to support evidence-based dietary guidance. Sarah is developing a comprehensive database to assess the health and environmental impacts of foods in the Canadian context using a life cycle assessment (LCA) approach.

Navisha Weerasinghe
Navisha’s doctoral research critically examines the historical, policy, material, socioeconomic and environmental conditions that shape the use of gloves in hospitals settings. This includes understanding tensions between patient safety, hospital-based infection control and the medical device industry, as well as examining the decision-making processes that are mobilized to promote or discourage glove use in practice. Her previous research looked at mapping the existing evidence on the role and impact of plastics in health products and their packaging.
