We are interested in understanding the origins of biodiversity from the level of local adaptation and limiting gene flow in single landscapes, through the genetics of entire species' ranges, to understanding the causes of diversification of entire clades. We are also interested in the impacts of human activities (e.g. habitat fragmentation, climate change, contaminants) on species at risk. We work mostly on amphibians and reptiles but also have work on birds, mammals (polar bears), and fish (char and whitefish).

Our Approaches

We use genomics and transcriptomics, environmental DNA surveys, morphometrics and sonographic and colour analyses to quantify variation across the distributions of organisms. We often combine these with experimental approaches (phonotaxis, hybridization experiments), GIS and niche modeling, and automated climate measurement to understand the causes and consequences of diversity across geographical and temporal scales, and to assess the impacts that human activities have had in wild populations.
