I am an eco-hydrologist with research spanning the continuum of natural through urban watersheds. A goal is to develop and incorporate principles learned in unmanaged ecosystems as part of urban ecosystem restoration. I have a major interest in the role of forests and tree canopy on flooding and drought, the provision of high-quality freshwater, coupled water, carbon and nitrogen cycling, and vulnerability to climate and land use change. My current urban environmental research has an emphasis on the design, analysis and simulation of green infrastructure on urban ecosystems and human well being, and the development of computational tools to facilitate collaborative and participatory research, management and design for watershed restoration.
