My research focuses on transportation planning and how metropolitan land-use patterns contribute to uneven economic development and social disparities. My work argues for improving transportation systems by shifting from mobility to accessibility as the primary criterion by which transportation policy is evaluated. I focus 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 to offer a basis for advancing policy reform, and explaining how accessibility is experienced differently by race, ethnicity, gender, age, and income. I am the Director of Doctoral Studies in Urban and Regional Planning, and I serve as a Steering Committee member and Treasurer for the progressive planning organization Planners Network. I am a certified planner and a registered professional engineer with work experience in both the private and public sectors and in international settings.
