个人简介

I am fascinated with how environmental variation in time and space (spatiotemporal heterogeneity) affect the diversity and functioning of communities. This variation is epitomized by seasonal environments, including the communities that I work in: vernal pools and rock pools. My research also encompasses food webs, metacommunities, latitudinal gradients, spatiotemporal linkages, eutrophication, species invasions, and disturbance ecology. Courses taught include General Ecology, Population and Community Ecology, Quantitative Methods in Biology, Introduction to Scientific Analysis, Seminar in Ecology, and Freshman Seminar.

研究领域

My research primarily examines how processes at different spatial and temporal scales produce patterns of biodiversity and functioning in communities. I approach this within a metacommunity framework whereby local (e.g., competition and predation) and regional (e.g., dispersal) processes contribute to community dynamics. Recently, this research has expanded to examine spatial patterns of diversity along latitudinal gradients. In addition, I am interested in the movement of materials across the land-water interface in both time and space and its consequences on communities. Further, my research also links ecological principles with conservation, including eutrophication, species invasions, and climate change. This research is conducted in seasonal freshwater ecosystems, including California vernal pools and rock pools. Here is a sampling of the research currently being conducted in my lab:
