I'm an Associate Professor in the Department of Environmental Sciences, University of California Riverside.  My main area of expertise is in Catchment Hydrology and Spatial Analysis. I use observational data and various modeling tools to understand hydrologic processes such as groundwater recharge, surface water-groundwater interactions, and land surface processes at a catchment scale. I have extensive experience in spatial analysis and custom application development for hydrological models. My research interests are in the application of integrated hydrological models to characterize surface water/groundwater/atmospheric interactions, computationally efficient hydrologic model development, ecohydrology and application of remote sensing and isotopic data in characterizing hydrologic cycle.
