Tierra Bills

Tierra S. Bills is an Assistant Professor of  Public Policy and Civil and Environmental Engineering at the University of California, Los Angeles. She specializes in the measurement of transportation planning and system outcomes, and travel demand modeling, with a special emphasis on transportation equity. Dr. Bills brings a unique and innovative perspective to the challenge of transportation inequity, aimed at impacting transportation science, practice, and quality of life for disadvantaged communities. She has worked in the transportation equity domain since 2009 and her current work builds off this long track record, including her master’s research, dissertation work, study and training as a Research Scientist at IBM Research, Michigan Society Fellowship research, and previous work as an Assistant Professor at Wayne State University.

Dr. Bills has extensive training in travel demand modeling and is engaged in ongoing work on representation of transport disadvantaged groups in household travel surveys, which are traditionally used to estimate and validate travel demand models. This is the first step to developing travel models capable of reflecting the preferences and behaviors of disadvantaged travelers and fine-grain transportation equity outcomes. Dr. Bills also works to advance accessibility measurement for transportation project evaluation, and develops strategies for ranking alternative transportation plans using equity-based criteria. Her work is published in a range of journals including Transport Policy and Transportation Research Record, and a recent contribution to the popular planning research press: The Metropole. She also currently serves as a Guest Editor on a Special Issue of Transportation Research Part D.

Dr. Bills has a strong record of advocacy for transportation equity and representation in STEM fields, including providing testimony for the a U.S. House of Representatives’ subcommittee hearing (see: https://science.house.gov/hearings/field-hearing-smart-mobility-its-a-community-issue), membership on the Equity in Transportation Committee of the Transportation Research Board, and co-developing an entry on her research in the ColorMePhD coloring book series (see: https://ce.berkeley.edu/news/2511).

Frederick Zimmerman

Frederick J. Zimmerman is an economist with a background in the political economy of health and social policy. His research illuminates the intersection of economics and the determinants of health.

Dr. Zimmerman has a particular interest in how economic structure—including poverty and inequality and housing markets—influence population health. Research topics have included the measurement of health equity; the effects of housing affordability on health; transportation and health; media use and child development; and the opportunity costs of medical spending.

Dr. Zimmerman’s work has integrated economic, sociological, and psychological perspectives of behavior into a multi-level theory that unifies both individual and population-level determinants of health. His current research is in the UCLA Center for Health Advancement, where he has developed measures to systematically track health equity over time and across jurisdictions. His Win-Win simulation model of the impact of health and social policy on population health has shown how high-school graduation rates, crime rates, and local government finances are affected by multi-sectoral interventions in several jurisdictions around the country.

The New York Times, NPR, the BBC, Radio France Internationale and many other media outlets have covered Dr. Zimmerman’s research.

Dr. Zimmerman teaches classes on Advanced Statistical Research Methods, Determinants of Health, and Public Health Ethics.

Margaret M. C. Thomas

Margaret (Maggie) Thomas is Assistant Professor of Social Welfare at the UCLA Luskin School of Public Affairs. Her scholarship and teaching emphasize structural sources of oppression and privilege, grounded in her practice experiences working with children, youth, and families facing social and economic marginalization.

Dr. Thomas’s research focuses on the wellbeing of economically marginalized individuals and families through the lens of policy causes and solutions to material hardship and poverty. She conducts two primary streams of research. First, she examines material hardship and its consequences for other domains of wellbeing, such as child protective services involvement (CPS) and health and mental health outcomes. Second, she analyzes policy impacts on poverty and hardship, such as Earned Income Tax Credit (EITC) and Supplemental Nutrition Assistance Program (SNAP) consequences for material hardship experiences. Dr. Thomas’s current research projects include a multi-year, randomized controlled trial testing the effects of guaranteed income receipt on material hardship and other domains of wellbeing; a study of the structure and systemic causes of the relationships between food insecurity and mental health; and work examining the relative roles of material hardship and income poverty in shaping child and family wellbeing, including in relationship to CPS involvement. Throughout her research, Dr. Thomas prioritizes engaging and training student research collaborators, responding to community members’ needs for and interest in research engagement, and sharing research findings in accessible ways.

Dr. Thomas teaches courses in Social and Economic Justice and Child and Family Well-Being, including Foundations of Social Welfare Policy (SW 214A), Social Welfare Research Methods (SW 213A), and Poverty, the Poor, and Social Welfare (SW 290L). Her teaching emphasizes social and policy systems, attends to structural forces that create marginalization and opportunity, and supports students’ development of meaningful, relevant knowledge and skills.

Dr. Thomas’s work has been supported by the Horowitz Foundation for Social Policy, the Society for Social Work and Research, and the UCLA Council on Research. She was previously a Postdoctoral Research Scientist at Columbia School of Social Work, where she worked on the Fragile Families and Child Wellbeing Study.
