John Pucher, Ph.D., is Professor Emeritus of Urban Planning at Rutgers University’s Bloustein School of Planning and Public Policy, where he taught and conducted research from 1978 to 2014. Widely regarded as one of the world’s foremost authorities on walkingˈ and cycling policy, John has spent more than 25 years analyzing and comparing trends, policies, and outcomes in Europe, North America, Australia, and Asia. His groundbreaking comparative studies—documenting how integrated infrastructure, traffic calming, bike-share systems, land-use policies, and training programs dramatically increase cycling safety and modal share—have shaped national strategies in the United States, Canada, Australia, and beyond. Governments, cities, and advocacy organizations worldwide routinely cite his work as the evidence base for investing in active transportation. John has authored or co-authored four books and over 200 peer-reviewed articles. His latest, Cycling for Sustainable Cities (MIT Press, 2021, co-edited with Ralph Buehler), is considered an essential reference for planners and policymakers pursuing low-carbon, equitable, and healthy urban mobility. A frequent keynote speaker and visiting professor in Germany, the Czech Republic, Canada, and Australia, John continues to advise international agencies and mentor the next generation of researchers. When not analyzing cycling data, he enjoys long-distance touring by bicycle, exploring architectural history, travel, meditation, and reading.
