Research Interests:
I study relationships between insects, plants, and the environment. My research focuses on how species are distributed in space and time, how networks of interactions help structure communities, and the consequences of those interactions for community function and stability. Pollinators, many of which are in decline, are essential for the function of many natural and managed habitats. It is therefore important to understand how pollinators respond to disturbances such as habitat loss and climate change, but also how they respond to conservation efforts aimed at preserving their biodiversity. I use a combination of large- and small-scale experiments, observational studies, and mathematical modeling to explore questions in basic and applied ecology.
