Joe Grengs teaches courses in transportation planning, spatial analysis, and a doctoral research seminar. He serves as the Coordinator of the Transportation Planning concentration for the Urban and Regional Planning program, and is the Director of Doctoral Studies in Urban and Regional Planning. His research focuses on transportation planning and how metropolitan land-use patterns contribute to uneven economic development and social inequalities. His work argues for improving transportation systems by shifting from mobility to accessibility as the primary criterion by which transportation policy is evaluated. He focuses on showing how the concept of accessibility offers a more effective evaluation tool for advancing social justice than current planning practices, developing methods for making intermetropolitan comparisons of accessibility, and explaining how accessibility is experienced differently by race, ethnicity, gender, age, and income. He serves on the Steering Committee and is Treasurer for the progressive planning organization Planners Network, and he also serves on the Executive Committee and is Treasurer for the Association of Collegiate Schools of Planning (ACSP). Joe is a member of the American Institute of Certified Planners (AICP) and a registered professional engineer, with work experience in both the private and public sectors, and in international settings. He holds a Bachelor of Civil Engineering and a Master of Urban and Regional Planning from the University of Minnesota, and a PhD in City and Regional Planning from Cornell University.
