Mark M. Chambers is an historian at Stony Brook University in Long Island, New York, where he also earned a Ph.D. in United States environmental history. Mark teaches and writes about the human intersections with the environment, with science and with technology, which is evidenced in his first book, Gray Gold: Lead Mining and Its Impact on the Natural and Cultural Environment, 1700–1840 highlighting the amalgamation of Native American early mining and smelting techniques with settlers and African slave practices. Mark came to EDGI in June 2020 following the death of George Floyd, and he desired to better understand the significance of social justice. While working with EDGI, Mark spent eighteen months as a Rita Allen Civic Science Fellow and he started to think and write about the influences that environmental justice activists have had on the National Institutes of Environmental Health (NIEHS) and the Environmental Protection Agency (EPA) related to community-based participatory research to protect human health.
