My research focuses on how environmental variation (in space and time) affects biodiversity and functioning of ecological communities.  Laboratory, mesocosm, field, and data mining studies are used with seasonal wetlands (primarily vernal pools and rock pools) to address questions at all ecological levels (individual to ecosystem).

My students and I research a variety of taxa, including bacteria, algae, plants, invertebrates, and vertebrates. Topics include metacommunities, spatial ecology, conservation biology, food webs, eutrophication, species invasions, restoration, endangered species, and disturbance ecology.

I was a Fulbright Scholar (2017 - 2018) Department of Evolutionary & Environmental Biology, University of Haifa (Israel) & Laboratoire de Botanique, Mycologie et Environnement, Université Mohammed V- Rabat (Morocco). I currently serve as a Fulbright Ambassador.
