Adam Millard-Ball
I’m a professor of urban planning at the UCLA Luskin School of Public Affairs, where I also direct the UCLA Institute of Transportation Studies. My research and teaching address the twin challenges of transportation and climate change. I bring an interdisciplinary perspective from economics, geography, data science, and urban planning to analyze the environmental consequences of how we plan our streets and move around our cities, and to identify and evaluate policies to reduce greenhouse gas emissions. I am also affiliated faculty at the Institute of the Environment and Sustainability and serve as the Review Editor of the Journal of the American Planning Association.
Before joining UCLA, I taught in the Environmental Studies Department at UC Santa Cruz, and in the Department of Geography and McGill School of Environment at McGill University. Before entering academia, I was a Principal with transportation planning firm Nelson\Nygaard Consulting Associates. I hold a PhD in Environment and Resources from Stanford University and an MA in Geography from the University of Edinburgh.
