Darryl B. Hood, Ph.D. is a Professor and Dean’s Fellow in the Division of Environmental Health Sciences, College of Public Health. Prior to joining The Ohio State University at Meharry Medical College, Dr. Hood led what has come to be known as the most successful Minority S11 NIEHS-sponsored initiative referred to as the “Vanderbilt-Meharry Advanced Research Cooperation in Environmental Health (ARCH) Program (2006-2011). The research conducted under this consortium contributed to the Integrated Risk Information System (IRIS) scientific database that the USEPA used to assess the levels of polycyclic aromatic hydrocarbons (PAH) emissions from point sources. The 2016 IRIS re-assessment of PAHs represented a public policy change that served to dampen the disparate health effects associated with PAH environmental exposures. At the Ohio State University, Dr. Hood has continued his innovation in discovery as the co-architect of the novel Public Health Exposome framework and analytics with an environmental justice lens.
