Research biologist

Ariane Dumas is a research biologist at the Public Health Agency of Canada's (PHAC) National Microbiology Laboratory. She works in the Public Health Risk Sciences Division, in the unit responsible for tick-borne diseases. In particular, her work involves studying environmental and population risk factors, such as the impact of climate change on these diseases, and optimizing surveillance and control efforts.

Current research and/or projects

Dr. Dumas' research aims to improve the resilience of populations to the risks posed by tick-borne diseases in Canada. Her research focuses on the links between wildlife, human populations and the environment, and more specifically on striking a balance between environmental conservation and public health protection. Dr Dumas specializes in the ecology and epidemiology of tick-borne diseases, spatial statistics, and the design and implementation of eco-epidemiological studies.

Research and/or project statements

  • Anticipate future risks from tick-borne diseases in a context of climate change.
  • Develop and evaluate interventions to reduce the risk of tick-borne diseases while enhancing biodiversity protection in peri-urban natural habitats.
  • Develop methods for optimizing tick-borne disease surveillance, particularly through wildlife monitoring and community science.
