Welcome to our ecology and limnology lab in the Department of Biology at York University!

Broadly, we are interested in predicting the effects of environmental stressors, such as climate change, invasive species, and habitat alteration, on lakes. There are opportunities for undergraduate and graduate students in my laboratory. If you are interested in joining the lab, please contact me here!

There is currently one post-doctoral researcher opportunity available in the laboratory. We are looking for a post-doctoral researcher with technical expertise in climate modelling to provide climate model projections of key cryosphere variables and their drivers across the Canadian Arctic that can be used to better understand the impacts, risks, and adaptation options available to support safe local and regional marine and overland mobilities. Please see the advertisement here.

Winter is changing. With the recent warming patterns that are expected to continue, lakes are freezing less often, for shorter periods of time, or for the very last time. In the lab, we explore how patterns of lake ice have shifted over recent centuries and what these patterns might look like in the future, including the implications for humans and wildlife.

Human-induced environmental stressors are among the leading drivers of change in freshwater ecosystems. We are currently researching the impacts of multiple stressors on water quality, primary production, and nutrient content in lakes around the world. We use big data and machine learning to address novel research questions in global change biology.

Our research has increased our understanding of how different taxa and ecological communities respond to environmental stressors along a gradient of spatial and temporal scales. We also develop quantitative frameworks to predict the effects of environmental stressors on wide-ranging ecosystems.
