Research Professor at the University of Michigan’s Institute for Social Research, and Professor in the University of Michigan’s School of Public Health, Dr. Clarke received her Ph.D. in Public Health from the University of Toronto in 2000. Her research interests are in social epidemiology, social gerontology, life course perspectives, models of disability, and population health. Her research examines the role of the built and social environment for disability, cognitive function, and social participation.  She has used various methods to capture characteristics in the built environment, including the use of secondary data sources (e.g., Census, NETS), in-person neighborhood audits (using Systematic Social Observation), and virtual web-based neighborhood audits (using Google Street View). She has compared the reliability and validity of these different methods, publishing one of the first papers on the use of Google Street View for this purpose. She also directs the National Neighborhood Data Archive (NaNDA) ( a nation-wide repository of publicly available contextual data spanning close to two decades. The goal of NaNDA is to minimize redundancy in the creation of contextual measures across federally funded research projects and to promote the examination of spatial contexts as they relate to health inequalities in other survey, cohort, or clinical data.

Research Projects

Rehabilitation Research and Training Center (RRTC) on Promoting Healthy Aging for People with Long-Term Physical Disabilities

(Administration for Community Living / DHHS 90RTHF0001-01-00)

The aim of this National Rehabilitation Research and Training Center (RRTC) is to identify environmental factors that are associated with healthy aging for individuals with long-term physical disabilities from diverse backgrounds, particularly those from low income and racial / ethnic minority communities. To date, there has been little research on environmental factors to guide interventions and treatments to improve the health of persons aging with long-term physical disabilities. This project will begin to fill this gap in knowledge by examining the role of characteristics in the social and built environment as they interact with underlying impairments and activity limitations to either hinder or promote the full participation of individuals with physical disabilities in society. The end goal of the Center is to develop interventions to modify environmental factors to enhance the health, functioning and participation of individuals aging with long-term physical disabilities. The Center serves as a national resource center by providing information, training, and technical assistance to a variety of groups / stakeholders. We engage key stakeholder groups, particularly disability and aging related organizations, to bridge programs and practices for older adults and people with disabilities and maximize the relevance and usability of the new knowledge generated by the RRTC.

A National Neighborhood Data Resource to Understand Inequities in the Health and Socioeconomic Impacts of COVID-19 in the United States

(NIH/NINR; U01NR020556)

The consequences of the COVID-19 pandemic have been unequally felt by individuals and communities across the United States. To understand these patterns, we will create, integrate, and share data on neighborhood characteristics, both before and since the pandemic, that can be readily linked to existing survey or cohort studies at various levels of geography. This national neighborhood data (NANDA) resource will support the scientific community in understanding the mechanisms that may convey risk and resilience, particularly in underserved and vulnerable populations, and will allow us to more effectively prepare for the next public health emergency.
