Research Interests: My research program answers basic and applied questions about hydrologic processes across a range of spatial and temporal scales. I am particularly interested in understanding the linkages between global scale oceanic-atmospheric climate forcings on interannual to multidecadal timescales and hydrologic variability that affects local to regional surface water and groundwater resources in semiarid and arid environments. I use observational, laboratory, and modeling (numerical, probabilistic, stochastic, and spectral) approaches to answer important questions about hydroclimatology, land-atmosphere interactions, the global groundwater crisis, nitrogen cycling and nitrate contamination in groundwater, and the water-energy-food nexus. My research informs water managers and policy makers at local, national, and international levels toward sustainable water resources.

Research Interests: Coastal flood hazard modeling and the interaction with sea-level rise and climate change. The latest research on climate change indicates that global sea level will rise at least 0.5 meters by 2100 and that the frequency of extreme precipitation events will increase in most parts of the world. In California, where more than 70% of the state’s population lives in coastal counties, several efforts are underway to map and assess shoreline vulnerability to flooding due to sea level rise (SLR). Less is understood about how climate change will affect fluvial flooding, particularly in coastal areas where changing stream flows will interact with rising seas and storm surge. Communities around the San Francisco (SF) Bay are especially vulnerable to flooding from the compounding of these hydraulic processes. My research contributes to the emerging body of work on climate change and compound flood hazard by modeling the effects of future precipitation and SLR on flood extent in a coastal creek and estuary system in the northern SF Bay. My thesis will also explore whether vulnerable populations will be disproportionately effected by the expected changes in flood extent.
