I am associate professor and chair of the Department of City and Regional Planning at UNC Chapel Hill where I also serve as Director of the Carolina Transportation Program. I recently returned from a year at the Institute of Transport Studies at the University of Leeds as the Fulbright Distinguished Chair.

My research focuses on youth and young adult mobility and addresses cross-cutting policy questions in the fields of planning, education, energy, and public health. My work on children’s travel documents sharp declines in walking and biking to school over the past forty years and examines the causes and impacts of this decrease.  Much of my recent work looks at the millennial generation and examines the causes and impacts of recent declines in automobility.

I received my undergraduate degree from Harvard in engineering and chemistry and my PhD in city planning from UC Berkeley. Prior to becoming a professor, I worked as a consultant for Cambridge Systematics and Mercer Management Consulting (now Oliver Wyman).
