Research Interests

I am broadly interested in understanding how climate change, land use change and other anthropogenic influences alter the dynamical interactions that shape ecosystems, and lead the Laboratory of Quantitative Global Change Ecology at UTSC. My research blends mathematical and statistical modelling with field data collection and the analysis of existing long-term datasets, in an effort to identify the mechanisms driving change, forecast likely future impacts of global change, and propose mitigation strategies to address pressing conservation and wildlife health concerns. I take a global perspective and work on a variety of systems, ranging from the High Arctic to the tropical rainforests of Central America. Current efforts primarily focus on (a) global change impacts on large mammals, and (b) global change impacts on parasitism and disease spread.
