Prof. Davies is a biodiversity scientist cross-appointed in the Departments of Botany and Forest & Conservation Sciences. His work explores how the evolutionary history of species—their phylogeny—can inform our understanding of their present day ecologies. He is co-author of the book Phylogenies in Ecology. His research addresses the consequences of the massive rearrangement of biological diversity we are precipitating through profound human-driven changes to the natural environment. His research interests range from understanding patterns of extinction risk in plants and animals to the global drivers of pathogen transmission and disease emergence.
Prof. Davies was a coordinating lead author on the biodiversity section of the recent UNEP Global Environment Outlook report—GEO6: Healthy Planet, Healthy People, and is a member of the Biodiversity Research Centre and the Interdisciplinary Biodiversity Solutions cluster (IBioS) at UBC. He is also an associate member of the African Centre for DNA Barcoding at the University of Johannesburg, South Africa.
