My research focuses on questions relating to the conservation and evolution of biodiversity: what processes determine species' distributions? how do distributions and abundances respond to environmental change? how does biodiversity contribute to human well-being? Deepening our understanding of these questions requires melding ecological and evolutionary theory, and will be crucial for developing effective conservation strategies in a time of rapid global environmental change. My expertise is in the application of modern computational technologies, including ecological modelling, remote sensing, GIS, and machine learning. Main research areas include:

• Modelling species' distributions: I have been active in advancing the theory and practice of Species Distribution Modelling, including for discovering new species, predicting respones to environmental change, and estimating the risk of species' invasions.
• The impacts of climate change on biodiversity: I use empirical records and modelled scenarios to understand how species' distributions and abundances respond to climate change, including developing methods to assess species' vulnerability for conservation prioritization.
• Nature's benefits to people: I aim to deepen our understanding of how biodiversity benefits human well-being, for instance through pollination and pest management in agricultural systems, and the resilience of such ecosystem services to environmental change.
• The geography and ecology of speciation: Using species-rich endemic radiations of geckos, chameleons and snakes in Madagascar as a study system, we explore the geographic and ecological mechanisms by which speciation occurs.
