Julia (she/her/hers) is a second-year doctoral student in the Health Psychology program at the University of British Columbia. She received her Master’s in Health Psychology from the University of British Columbia in 2022, and her Bachelor of Science in Psychobiology (minor Gerontology) from the University of California, Los Angeles in 2020.

Julia’s overarching goal is to build a program of research that informs policy and intervention work to improve population health. She integrates theories and perspectives from integrates theories and perspectives from health psychology, epidemiology, biostatistics, and translational science to identify, understand, and intervene upon the dimensions of prosocial behaviors (e.g., volunteering, helping behaviours, charitable giving) and psychological well-being (e.g., purpose in life) that improve health and well-being.

Recognizing the great importance of translating research into meaningful, real-world, population-level change, Julia engages in multiple translational science efforts with non-academic partners. She works with the Canadian Red Cross (to enhance accessibility, equity, and benefits of volunteering across Canada) and was a Research Fellow in the Consortium on Analytics for Data-Driven Decision-Making (to receive formal training in population research that supports evidence-informed decision-making).

Research interests include: health psychology, psychological well-being, prosocial behaviours, gerontology/aging, epidemiology, translational science
