Jens Ludwig is the Edwin A. and Betty L. Bergman Distinguished Service Professor, director of the University of Chicago’s Crime Lab, codirector of the Education Lab, and codirector of the National Bureau of Economic Research’s working group on the economics of crime.
Sarah is a principal research scientist with 20 years of mixed-methods research and evaluation experience with a focus on qualitative methods. Over the past decade, much of her work has also involved designing, implementing, and evaluating training. Although her work has covered many topics, she is increasingly interested in the impact of natural disasters on morbidity and mortality as well as cancer prevention, screening, and management.
Sarah currently leads NORC’s disaster mortality work including a large cross-center project for the Centers for Disease Control and Prevention (CDC) aimed at improving processes for identifying and reporting disaster-related deaths. Through evaluation and research activities, NORC designed several resource guides, a suite of supplemental materials, and a comprehensive training all publicly available on CDC’s website. This project builds on the work she led for CDC developing a toolkit and accompanying training for medicolegal death investigators to collect data after natural disaster and extreme weather events.
Sarah has also worked with the Health Resources and Services Administration (HRSA)’s Division of Women’s Health on several cervical cancer related trainings and the American Cancer Society (ACS) on evaluating patient navigation programs and Round Table efforts. Prior to joining NORC, Sarah worked as a qualitative analyst on the Chicago Health, Environmental Exposure, and Recreation Study (CHEERS), where she examined the best ways to communicate with local Chicago waterway users about water quality and safety and an evaluation consultant with the Illinois Caucus for Adolescent Health.
Adam Zelizer studies legislative politics, with a focus on causal inference. His research examines how legislators make decisions – for example, how they acquire expertise from policy research and influence one another through deliberation – and the effects of individual decision-making processes on policy outcomes. One goal of this research is to figure out which legislative processes work, in the sense of leading to more informed, effective, and broadly-supported public policies, and which don’t.
He received his Ph.D. in Political Science from Columbia University in 2018. He also holds a BA in Political Economy from Columbia University. He joins Harris as an Assistant Professor after spending a year as a postdoctoral researcher and instructor at Harris, during which he taught Analytical Politics II and Field Experiments for Public Policy. His research has been supported by the National Science Foundation, Russell Sage Foundation, Cato Institute, Open Society Foundations, and Abdul Latif Jameel Poverty Action Lab.
Dan is a senior research director with the Public Affairs & Media Research department. During his tenure, he has worked on dozens of projects, including many with The Associated Press-NORC Center for Public Affairs Research. He has experience with questionnaire development, data management, data review, analysis, and reporting on a wide variety of survey projects of varying complexities.
Dan specializes in data delivery for large, high-profile surveys. He currently leads the data delivery for the National Survey of Fishing, Hunting & Wildlife Associated Recreation, which provides important data on participation and expenditures related to these outdoor activities. From 2018 to 2024, Dan led the data management and data delivery for AP VoteCast, a groundbreaking election survey that allowed for more precise measures of voters’ opinions. VoteCast surveys included more than 120,000 interviews conducted in the week before the election and involved rapid, continuous data delivery on Election Night for use in news coverage nationwide.
Communicating survey findings to a wider audience has been a hallmark of Dan’s tenure at NORC. A recent example is the 2024 Los Angeles Times/NORC Poll on LGBTQ+ Communities, which updated a 1985 LA Times study to track how attitudes in the United States have changed toward gay and lesbian people. He has also served as project manager on The Long-Term Care Poll, a series of surveys conducted by The AP-NORC Center from 2013 to 2023 that explore issues related to aging in America.
Dan holds a MA in Political Science from The George Washington University. Prior to joining NORC, he worked at the George Washington Institute of Public Policy.
Juan Carlos is a senior research scientist in The Associated Press-NORC Center for Public Affairs Research. He has significant experience managing complex multi-mode surveys in the United States, Europe, and Latin America.
Juan Carlos has designed, conducted, and managed surveys on a variety of topics, including attitudes towards democracy, rule of law, the role of religion in public life, and issues related to public health, such as child development and housing conditions and risk factors for suicide among veterans and military service members.
