Research Interests

The diversity of life has long fascinated humans. The processes that allow species to coexist and thus maintain diversity in ecological communities form the research focus of our lab. We study why some species are common but most species rare. What mechanisms help rare species persist and keep communities diverse? Further, in a world overwhelmingly shaped by humans today, we want to know how human influence affects the mechanisms that maintain diversity and restructure ecological communities. To this end, we combine ecological theory, experiments and observational field research with advanced statistical models. In particular, we use functional traits - heritable characteristics that mediate species’ response to different conditions - to understand patterns and processes that shape biodiversity in different ecosystems. We use plant communities as model systems, but the concepts apply across many ecological communities. Ultimately, our lab is driven by theory and curiosity.

Research in the lab can be broadly grouped into the following themes: 1) Climate change impacts on forest regeneration, 2) Ecological dynamics in human-modified forests, and 3) Functional traits and species response to gradients. See here for more details of our research.
