Mary Pattillo serves as the Harold Washington Professor of Sociology and Chair of the Department of Black Studies at Northwestern University's Weinberg College of Arts and Sciences, with additional affiliation at the Institute for Policy Research. Her work centers on Chicago's urban landscape as a critical site for examining systemic racism and inequality. Her academic foundation includes a PhD in Sociology from the University of Chicago (1997) and a BA in Urban Studies from Columbia University (1991), establishing her expertise in urban analysis and racial dynamics. Pattillo's research agenda prioritizes race and ethnicity, urban sociology, and inequality through the lens of Black communities, with particular focus on housing, criminal legal systems, and the Black middle class. Her ethnographic approach reveals how spatial dynamics shape life outcomes, as demonstrated in her influential books Black Picket Fences (1999) and Black on the Block (2007), which introduced the pivotal "middlemen/middlewomen" framework for understanding professional Black roles in mediating inequality. Current work advances the "Black Advantage Vision" paradigm to reframe racial inequality research. Her publication trajectory shows deepening engagement with structural racism across multiple domains: from early neighborhood ethnographies to contemporary analyses of monetary sanctions and placemaking. This evolution reflects an interdisciplinary expansion into criminology, policy studies, and cultural sociology while maintaining core commitments to urban inequality and Black community resilience. Major recognitions include: Election to the American Academy of Arts and Sciences (2020) Robert E. Park Award for Best Book (2008) Oliver Cromwell Cox Best Book Award (2000) Fulbright Scholar designation (2019-2020) Weinberg College Community Building Award (2018) Outstanding Academic Book Award (2000) Pattillo actively mentors students through courses like Urban Ethnography and Sociology of Housing while leading significant research initiatives on school choice and criminal legal sanctions. Her community impact extends through board service at the W.T. Grant Foundation and Chicago Appleseed Center, plus founding Urban Prep Academies. Current projects examining Black safety in Chicago demonstrate her sustained commitment to community-engaged scholarship addressing urgent urban challenges.
Jonathan Levine is a Professor of Urban and Regional Planning at the University of Michigan's Taubman College of Architecture and Urban Planning, where he has been faculty since 1991. His work focuses on transportation planning, housing and equitable development, and land use and environmental planning, with a particular emphasis on shifting from mobility-based to accessibility-based planning paradigms. Levine's educational background includes: Ph.D. in City and Regional Planning from the University of California, Berkeley M.C.P. in City and Regional Planning from the University of California, Berkeley M.S. in Engineering (Civil Engineering-Transportation focus) from the University of California, Berkeley B.S. in Political Economy of Natural Resources from the University of California, Berkeley His research centers on the potential and rationales for policy reform in transportation and land use. Levine argues that a shift in the transportation and land-use planning paradigm from a mobility to an accessibility basis is compelled by transportation theory and would be transformative to planning practices. His current work includes sponsored projects and the book "From Mobility to Accessibility: Transforming Urban Transportation and Land-Use Planning" (Cornell University Press, 2019), co-authored with Joe Grengs and Louis Merlin. He previously authored "Zoned Out: Regulation, Markets, and Choices in Transportation and Metropolitan Land Use" (Resources for the Future, 2006), which argued for policy reform based on expanding households' effective range of choices. Levine's recent publications demonstrate a clear trend toward accessibility-based evaluation of transportation systems and land-use planning. His articles explore topics such as comparing bus rapid transit and light rail, project-level accessibility analysis, overcoming the last-mile problem, and the effects of automated transit systems. His work consistently challenges traditional transportation planning paradigms and advocates for approaches that prioritize access to destinations rather than mere mobility. Levine's contributions to the field have been recognized with several prestigious awards: 2010 Chester Rapkin Award for best paper in the Journal of Planning Education and Research 2011 Residential Fellowship at the Rockefeller Foundation Center in Bellagio, Italy 2001 Excellence in Urban Policy Scholarship Award from the Association of Collegiate Schools of Planning and U.S. Department of Housing and Urban Development 1996 Best of Association of Collegiate Schools of Planning Award Levine has led significant research projects including Implementation of Accessibility-Based Evaluation for Transportation and Land-Use Planning funded by NEXTRANS, Sustainable Transportation for a 3rd Century addressing the last mile problem, and Accessibility Evaluation from Laboratory to Practice. His teaching portfolio includes Transportation and Land-Use Planning, Public Economics for Urban Planning, Research Design, and the MUP Capstone studio, where he guides students through real-world planning challenges. As a thought leader in urban planning, Levine regularly contributes to public discourse on zoning policies, housing diversity, and transportation planning. He has been featured in numerous media outlets discussing how land use policies impact sustainability, affordability, and racial justice, emphasizing that "zoning is behind all of it, and is not only the cause, but exacerbates it." His insights on the historical role of single-family zoning in perpetuating racial segregation have been particularly influential in contemporary housing policy debates.
