Carys Vyn

Carys Vyn is a PhD candidate in Epidemiology at the Ontario Veterinary College, specializing in One Health approaches to infectious disease modelling. Her research focuses on leptospirosis, a neglected, climate-sensitive zoonotic disease that affects both animals and humans. Carys integrates machine learning, Bayesian modelling, and GIS tools to investigate how environmental and socioeconomic conditions influence the spatial and temporal patterns of canine leptospirosis in Canada and the United Kingdom. By generating risk maps and identifying high-risk populations, her work contributes to more comprehensive surveillance and mitigation efforts. Through a One Health approach, she addresses the complex interplay of climate, animal hosts, and human activity in shaping disease risk. Carys’ research contributes to a deeper understanding of how the socioecological system influences emerging infectious diseases and supports evidence-based prevention strategies at the human–animal–environment interface.
