David King

David King is an Assistant Professor of Urban Planning at Columbia University’s Graduate School of Architecture, Planning, and Preservation. His research explores the impact of local transportation planning on the built environment, public finance and accessibility. As part of this research he has written about the phenomenon of cruising for parking and used spatial regression techniques to analyze travel behavior. He also studies how public policy influences the adoption of new technologies to address congestion, energy and environmental concerns. These issues are the focus of Professor King’s teaching through his courses covering planning techniques and methods, transportation and land use planning and transport policy.


Patrick Kinney

Dr. Patrick Kinney is a Professor at Columbia University’s Mailman School of Public Health in the Department of Environmental Health Sciences. Dr. Kinney’s teaching and research address issues at the intersection of global environmental change, human health, and policy, with an emphasis on the public health impacts of climate change and air pollution. His work in the 1990s on air quality and environmental justice in Northern Manhattan and the South Bronx led to important new insights into the impacts of diesel vehicle emissions on local air quality. Dr. Kinney has carried out numerous studies examining the human health effects of air pollution, including studies of the effects of ozone and/or particulate matter on lung health and on daily mortality in large cities. More recently, he developed a new interdisciplinary research and teaching program at Columbia examining the potential impacts of climate change on human health. Dr. Kinney was the first to show that climate change could worsen urban smog problems in the U.S., with attendent adverse health impacts. He also has projected future health impacts related to heat waves in the NYC metropolitan area. In a new research initiative, Dr. Kinney is working with clinicians at Columbia University Medical Center and New York-Presbyterian Hospital to understand how past and future climate may affect pollen-related allergic airway diseases. Dr. Kinney earned his doctorate at the Harvard School of Public Health, where he studied the effects of air pollution on lung function in children as part of the Harvard Six Cities Air Pollution and Health Study.

Andrea Rizvi

A_RizviAndrea Rizvi has a Ph.D. in Urban Planning Program from the Graduate School of Architecture, Planning and Preservation (GSAPP) at Columbia University, New York.  Her research focuses on the practice of infrastructure provision in developing countries.  Her doctoral research explored the impact of different types of planning process on project outcomes, drawing on case studies of Bus Rapid Transit (BRT) implementation in India.  Prior to embarking on her doctorate, she worked at the World Bank where she managed programs to deliver infrastructure services in poor urban and rural settlements.  She has over 15 years of experience as both a project manager and design practitioner in Australia, United Kingdom, South America and Eastern Europe.  She holds Masters Degrees from Massachusetts Institute of Technology in Technology and Policy (MSc.) and Environmental Engineering (MSc.) as well as an Honors degree in Civil Engineering from the University of Queensland in Australia.


Sarah Williams

Sarah Williams is currently Director of the Civic Data Design Project, which is new research lab that is part of Massachusetts Institute of Technology’s (MIT) School of Architecture and Planning School. The Civic Data Design Project develops innovative tools and techniques that allow for the visualization, collection and spatial analysis of the vast data sets we now store about the places we live. The lab employs data visualization and mapping techniques to expose and communicate urban patterns and policy issues to broader audiences. Williams is also currently faculty of MIT’s Graduate School of Architecture and Planning.
