Research Interests / Specializations:
Freshwater ecology, biodiversity conservation, community ecology, global change.
I am a freshwater ecologist motivated by research questions revolving around the ecology, biodiversity, and conservation of streams and wetlands. I am particularly interested in how the higher levels of biological organization (communities, metacommunities, and food webs) respond to global change stressors, focusing on the effects of hydrologic variability and drought. I have conducted most of my research in water-scarce regions of the world (the Mediterranean basin and the American Southwest), and I am fascinated by highly-dynamic freshwater ecosystems and their adapted biotas. Lately (as a Postdoctoral Fellow at SESYNC) I have been studying the effects of dams on flow regime alteration, via large data sets and time-series methods.
Research in my lab will focus on the following topics:
Joint effects of hydroclimatic anomalies and invasion on native freshwater biodiversity
Dynamics of freshwater metacommunities in highly variable ecosystems
Responses of riverine food-web structure to hydrologic regime shifts
Flow regime alteration and 'designer' environmental flows
Potential and limitations of wetland restoration for biodiversity conservation
