I obtained my B.A. in Physics from the University of California, Santa Cruz and worked at Intel before obtaining my Ph.D. in Physical Oceanography from the University of Washington.

Since joining the staff of the Climate Research Division at the Scripps Institution of Oceanography, Ive worked on such problems as El Nino prediction, numerical modeling of the ocean and atmosphere, and detection and attribution of human-caused climate change in the worlds oceans as well as in Western U.S. snowpack and streamflow.

I was fortunate to be a contributing author to the 2007 and 2013 United Nations IPCC reports, a reviewer of the United States Southwest Region National Climate Assessment, and originator of the LOCA data set used in the most recent California state and National Climate Assessments.

Much of my work revolves around assessing climate change and variability and how it might impact natural and human systems such as the electricity grid and water infrastructure in California and the Colorado River basin.
