Research Interests

I am interested in how terrestrial ecosystems respond to anthropogenically driven changes, particularly interactions between invasive species, land use and climate change.  I aim to improve forecasting of future changes to ecosystems, particularly risks of non-native plant invasions, using tools from biogeography and landscape ecology.  My research has implications for invasion ecology, natural resource management and biological conservation.
