I am Christine Sheppard, a plant ecologist with a research focus on biological invasions. Invasions by alien species are both fascinating and of great importance because they pose major threats to biodiversity, but also act as a natural experiment providing many insights about ecological and evolutionary processes. My main research objectives include understanding biotic interactions between native and alien species as well as among multiple invaders, predicting the long-term dynamics of plant invasions, and testing potential synergistic effects with various other factors of global change. To better understand the eco-evolutionary mechanisms associated with such invasion dynamics, I combine multi-species experiments and field studies with macroecological analyses. Beyond invasions, I am generally interested in biotic interactions, effects of global change and conservation of plant diversity.
