Urban Sustainability & Environmental Health Research Cluster

Welcome to the Urban Sustainability & Environmental Health (USEH) Research Cluster at the University of Michigan-Flint. The cluster was created out of a growing need to bring researchers, practitioners, and students with an interest or expertise in urban health and environmental science together to address topics ranging from sustainable and connected communities, to public health policy and resilient ecosystems. Considering that more than half of humanity now lives in cities, and ecological systems continue to be stressed, we believe that researchers from a myriad of disciplines are needed to promote planetary health. Therefore, the research group is interdisciplinary by design and have expertise in: healthy cities, public health, urban planning and policy, interactive marketing, data science, geospatial technology, environmental management, urban design, graphic art and design, chemistry, engineering, sociology, psychology, and computer science.


  • Drive scientific research among UM-Flint researchers, and their domestic and international partners, on critical urban and environmental health issues
  • Become a focal point for information exchange and cooperation among faculty, graduate students, practitioners, and community partners
  • Foster applied research and engage policy issues to improve our understanding of the interfaces among urban-environmental-health systems
  • To produce usable evidence, resulting from scientific publications and grant-funded projects, policy-makers can use to enhance the health of urban and natural areas

Current Research

We are developing a variety of interdisciplinary research proposals and have several projects within two main themes:

Ecosystem Management

Flint River Restoration
This project will evaluate current conditions in the Flint River in the City of Flint to support existing water quality improvement efforts intended by the Flint River Restoration Efforts.

Flint Drinking Water Assessment
Toxin monitoring in Flint drinking water. Evaluation of toxins in early embryonic development will ultimately be examined.

Urban Health Equity

Urban Foraging in Detroit
Urban agriculture is gaining some attention in cities throughout the world as a means to alleviate food insecurity, help restore ecosystems, and promote a deeper connection between nature and humans. Considering these, the goal of this project is to explore the physical and social neighborhood conditions which may support urban foraging behavior in Detroit, Michigan. The results of this study should assist practitioners with enacting policy to promote a forage-rich urban environment.

Reza Amini, PhD
Reza Amini  holds a PhD in sociology of aging, a Medical Doctorate (General Medicine), and a Master of Public Health. Within the last five years, he studied health care utilization and cognitive function among older adults living in the community. His educational background and research experience in public health enables him to cut across tightly-related disciplines and provide novel ideas about health determinants, including social determinants of health and people’s quality of life at the local, national, and international levels. Before starting his PhD, fifteen years of clinical practice experience and studying health problems and health needs among Iran-Iraq war survivors provided him with a deep insight into public health. One of Dr. Amini’s fundamental questions is how we can sustain or even enhance quality of life, particularly in later life when it is significantly affected by physiological dysfunction and lower social engagement levels.
