Research in my lab bridges community ecology with macroecology.  We focus on understanding feedbacks among processes that operate at the community scale and across regional to continental scales.  Using experimental field approaches primarily in benthic marine systems, we explore (1) the impact of species interactions on community assembly and ecosystem function, particularly resistance to invasion by non-native species, and (2) how these processes structure patterns of species diversity in space and time.  One of our principal interests lies in understanding how these dynamics change across the primary global biogeographic gradient, latitude.  Therefore, our field studies span the subarctic to the tropics.  See my lab website for more information.

In addition to pursuing my research interests, I direct the Ecology, Evolution and Biodiversity (EEB) Bachelor of Science degree program, which trains the next generation of scientists to pioneer new insights into the natural world, clarify the processes that maintain and change it, and develop innovative approaches to its conservation.

I also direct the Temple Ambler Field Station, which serves as a platform for faculty and student research, field courses, and year-round undergraduate research internships.  The Field Station supports research and field-based education across disciplines, with strengths in the environment and sustainability.  We also steward a 4-hectare forest research site, the Temple Forest Observatory, where researchers and students study the impacts of extreme weather on ecological and environmental dynamics.
