I am a research scientist affiliated with the Policy Institute for Energy, Environment, and the Economy at UC Davis; the Energy Analysis and Environmental Impacts Division at Lawrence Berkeley National Laboratory; the Institute of Transportation Studies at UC Davis; and the Transportation Sustainability Research Center at UC Berkeley. I am a member of the Alternative Fuel Committee and the Energy Committee of the Transportation Research Board of the US National Research Council.

I studied physics and engineering my first two years of college at UCLA, then studied urban planning, economics, philosophy, architecture, engineering, public policy, energy use in buildings, and more, for a bachelor’s and master’s degree at Berkeley. After a 3-year hiatus from university, I returned to study environmental science, economics, ecology, transportation energy, and engineering for a Ph.D. at UC Davis. After a one-year post-doc at Princeton, doing analyses of hydrogen energy for transportation, I started my current career as a professional researcher at the University of California, first at UC Davis, then at Berkeley, now back at UC Davis.

I’ve enjoyed (and sometimes still enjoy) hiking, water polo, mountain biking, swimming, tennis, bicycle touring, gardening, genealogy, body surfing, ski trekking, frisbee golf, rock climbing, triathalons, local neighborhood planning activities, skateboarding, travel, and mountaineering. I have three children. My wife is a writer and a therapist.
