Philippa Clarke received her graduate training in Epidemiology/Social Science and Health from the University of Toronto. She is a social epidemiologist and social gerontologist with substantive and methodological expertise in the role of the neighborhood environment for healthy aging. Her research examines the role of neighborhood built, physical, and social environments for disability, cognitive function, and social participation. She also directs the National Neighborhood Data Archive (NaNDA), a nationwide repository of publicly available contextual data spanning over two decades.

Lindsay Gypin is Data Librarian and Senior Project Manager for the Social Environment and Health Program in the Survey Research Center at the University of Michigan's Institute for Social Research, where she manages the National Neighborhood Data Archive (NaNDA). NaNDA is a federally funded open data repository that publishes free measures of neighborhood physical and social environments through ICPSR, supporting researchers studying how place shapes health and aging across the life course. Lindsay leads NaNDA's curation pipeline and works directly with researchers to help them find the right measures, understand geographic units and coverage, and link neighborhood data to their own study samples. She also serves as adjunct faculty in the MLIS program at the University of Denver's Morgridge College of Education. She brings over fifteen years of library experience and a focus on making data genuinely usable — well documented, well described, and easy to cite.

Grace Noppert is a Research Associate Professor in the Social Environment and Health Group at the University of Michigan's Institute for Social Research, where she co-directs the Biosocial Research Collaborative and serves as Deputy Director of the National Neighborhood Data Archive (NaNDA). Her research sits at the intersection of social epidemiology, infectious disease, and aging, examining how social and environmental exposures across the life course shape immune function in later life. Her work leverages cellular-specific immune and herpesviruses measures to identify the mechanisms linking social conditions to biological aging.
