I am an ecosystem scientist with specialized training in the hydrology and biogeochemistry of urban and restored riparian systems in arid and semi-arid regions. My scientific training is multidisciplinary and spans wide spatial and temporal scales, from trace gas fluxes over a period of hours in semi-arid urban streams to aquatic primary and secondary productivity in response to seasonal flooding in a Mediterranean river floodplain, urban runoff quantity and quality and catchment scale water balances based on physical measurements and remotely sensed data that span several years and climates.I am an ecosystem scientist with specialized training in the hydrology and biogeochemistry of urban and restored riparian systems in arid and semi-arid regions.
