My research focuses on the relationships between hydrological and ecological processes in studies relevant to the management of water resources. An overarching goal is to improve our ability to predict the effects of climate change and management actions on freshwater ecosystems, and the socio-economic and ecological benefits they provide. Through applied, cross-disciplinary investigations that employ hydrological and hydraulic modeling, empirical field studies, geospatial analysis, and ecological statistics, research in our group aims to inform sustainable, cost-effective policies for managing water. Core research and extension interests include:
environmental flow science
California water management and policy
spatial freshwater conservation planning
climate change risk assessment and adaptation
