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.
