My research investigates the interactions between plants and pollinators. I work at the population and community level to explore how changing distributions of local floral resources and landscape-level habitat influences bee communities, population growth of native bees, and plant pollination. I am keenly interested in elucidating the regulating factors of native bee populations. One general aim of my research is to apply basic ecological principals and approaches to real world problems, such as exotic species invasions, agricultural pollination, and the restoration of degraded lands. Current projects include:
- The influence of local floral diversity and landscape factors on the assembly of pollinator communities in restored prairie patches on mined land.
- Testing hypotheses of nest site and floral resource limitation of native twig-nesting bee populations.
- The application of stage-based matrix models to understand patterns of population demography of solitary bees.
- The role of native bees in the pollination of pumpkins and squash and their response to farm management practices.
- Mating patterns in invasive plant Lonicera maackii as a function of local environment and pollinators.
