Daniel is a professor in the Department of Epidemiology and Director of the Carolina Transportation Program at the University of North Carolina in Chapel Hill. His research focuses on the relationship between transportation and land development. He examines this relationship at various scales. At the individual level, he has studied the land value impacts of transit investments and the impacts of urban form on travel behaviour and physical activity. At the regional scale, he studies the relationship between regional policies and travel patterns, and how plans can be used to strengthen the reciprocal connection between transportation and land use. The work Daniel does is driven by practical problems and aims to inform planners and policy-makers. He collaborates closely with colleagues from multiple disciplines (health, nutrition, economics, geography, and public policy) and mentors students in contributing knowledge to the planning profession. The following is a short list of some of his current projects, selected academic publications and recent publications for practitioners: Examining how changes to the physical attributes of the environment like the location of trails, bus routes, rail systems, food outlets, and supermarkets are related to changes in physical activity and diets using cohort data; Studying how land management tools can be used to encourage transit oriented development, and related tools to recapture property value increases caused by public action; Identifying and understanding the causes and consequences of the rapid increases in motorcycle ownership and use in Latin America, using in-depth interviews and user surveys. Daniel also serves on the Editorial Board of five journals: Journal of the American Planning Association, Journal of Transport and Land Use, Journal of Transport and Health, International Journal of Sustainable Mobility and Journal of Architectural Planning and Research. Daniel holds a PhD from the University of Michigan at Ann Arbor and a Master of Science in Transportation from the Massachusetts Institute of Technology.
