We work to help generate the information and momentum required for society to shift toward more sustainable and equitable living.

We are a group of researchers based at Carleton University, in Ottawa, Canada. Our research primarily focuses on stewarding watersheds and conserving freshwaters. Read on to find out more about our current team members.

Dalal leads the Watershed Stewardship Research Collaborative. She is an environmental scientist, educator and science communicator with a special interest in rivers and lakes, as well as the social-ecological systems in which they are embedded. As an assistant professor of conservation science at Carleton University, she teaches landscape ecology, introduction to biological data, introduction to graduate studies, and contributes to research focused on freshwater conservation.
Sebastian is using evidence syntheses to investigate the effects of timber harvesting on freshwater biodiversity, water quality, and amphibians.
Maya's masters project looks at different percentages of timber harvesting and their impact on watershed quality + biodiversity. This research will hopefully allow us to identify a disturbance threshold.
Working with bats during my master's directed my curiosity towards the relationship between forests and the water features that bats often use for foraging. I am interested in understanding how changes in forest structure can modify communities of both insects and insectivores in riparian areas.
Lauren is examining watershed-specific cumulative threats to aquatic species at risk in the Great Lakes Basin. She is co-supervised by Dr. Andrew Drake at Fisheries and Oceans Canada.
Marion is investigating how disturbances caused by different land uses affect the water quality and macroinvertebrate diversity of protected streams in Quebec.
Chloée’s research seeks to inform best conservation practices within current protected areas, as well as where to target future area-based conservation, to best protect freshwater and its biodiversity in Canada. |
