Research Focus

Our lab works at the intersection of population and community ecology, focusing on how species interactions and climate change jointly influence population dynamics and distribution patterns. We use a combination of observational fieldwork, field- and greenhouse- based experiments, and modeling to explore how species interactions might impact future biodiversity patterns in a changing climate. Work in our lab focuses on four questions:

  • How does the impact of species interactions on populations and distributions change with climate?
  • Do responses to climate and species interactions vary systematically across broad spatial scales?
  • What are the mechanisms by which other trophic levels or guilds elicit population-level responses?
  • How will rare plant and animals respond to climate change?

Please get in touch if you are interested in learning more about what we do or joining the lab.
