I am an assistant professor in the Environmental Studies Department at the University of California, Santa Cruz.

My research bridges urban planning and environmental economics, and addresses some of the key challenges in transportation, energy and climate change policy. My current work examines global patterns of urban sprawl and car ownership, the effectiveness of local climate planning efforts, and the design of carbon trading programs. I also have broad interests in transportation planning and policy, particularly parking management programs to reduce vehicle travel and emissions.

Before coming to UC Santa Cruz, I was an assistant professor in the Department of Geography and McGill School of Environment, McGill University. I hold a PhD in Environment and Resources from Stanford University, and was formerly a Principal with transportation planning firm Nelson\Nygaard Consulting Associates.
