Senior Research Assistant, Zoology
Jacqueline Madill is an aquatic zoologist who studies Canada's native freshwater mussels, freshwater snails and the invasive zebra mussel.
- Malacology - Canadian Freshwater Mussels.
- Hirudinology - Canadian Leeches.
- B.A., Music, Pedagogy, University of Ottawa, 1999.
- B.Sc., Zoology, McGill University, 1969.
Jacqueline Madill studies and identifies aquatic animals of Canada, an interest that she has honed since joining the museum in 1973. She is also the museum's champion for Canada's lesser known animals such as microscopic zooplankton, leeches, freshwater mussels and snails. Jacqueline is known internationally as the "Leech Lady" for her expertise in leeches. She has surveyed aquatic life in the Rideau River, the Ottawa River, Lake Ontario, Gatineau Park in Quebec, and the British Columbia coastline.
Jacqueline is currently on a quest to locate populations of the 50 species of freshwater mussels that are native to Canada. Freshwater mussels are the most threatened and endangered group of animals in North America because of habitat loss and pollution.
