I am a senior research hydrologist for the U.S. Geological Survey, Branch of Western Regional Research, a research associate of the Scripps Institution of Oceanography, and a resident scientist at UNR/DRI in Reno. I have researched the hydrology, climate, and water resources of the West for over 30 years, focusing on regional surface water and groundwater resources and modeling, hydroclimatic variability, and climate-change impacts. I was physical-sciences team leader for DOI-DOD ecosystem planning in the Mojave Desert back in the 1990s, founding member of the CIRMONT Mountain Climate Consortium, climate advisor to the CALFED Bay-Delta Restoration Program in the 2000s, research advisor for USGS Surface-Water Discipline, member of the USGS Global Change Science Strategic Planning Team, lead author of the Water Resources chapter of the 2013 National Climate Assessment, editor of both State of (San Francisco) Bay-Delta Science reports, and a founding PI of the Center for Western Weather and Water Extremes at Scripps. I have degrees from the University of California, San Diego (Physics), Massachusetts Institute of Technology (Civil Engineering/Water Resources), and a PhD from the University of California, Los Angeles (Atmospheric Sciences). I am a hydrology Fellow of the American Geophysical Union, and a member of the Water Resources Committee of the American Meteorological Society. Along the way, I have authored or co-authored 120+ scientific articles and chapters in scholarly journals and books, 20+ government reports, and 70+ other articles in less formal outlets, with over 14,000 citations of my work in the scientific literature.
