D. Alan Warren, M.P.H., Ph.D.
Program Director, Environmental Health Science
Marine Science 205
Dr. Warren received his Bachelor of Science degree in Environmental Health from the University of Georgia in 1985 and a Master of Public Health degree from Yale University in 1987. The subject of his master's thesis was the development and application of an air sampling and analytical method for volatile acrylates, sensitizing chemicals used in the manufacture of optical fiber. He began his professional career as an industrial hygienist at the Georgia Tech Research Institute (GTRI) where he conducted more than 100 industrial hygiene surveys for Georgia employers under the State's OSHA Consultation Program. At GTRI, he also served as a principal or co-investigator on projects that assessed the exposure of forestry workers to herbicides during application and identified chemicals off-gassing from newly-manufactured optical fiber. In addition, he routinely directed and taught continuing education courses on asbestos abatement, respiratory protection, hazardous waste, emergency response and industrial hygiene methods.
In 1990, Dr. Warren returned to the University of Georgia to continue his graduate studies. As a doctoral student researching the pharmacokinetics of volatile organic solvents and their neurobehavioral toxicity, he was awarded a Department of Defense Science and Engineering Graduate Fellowship. Upon receiving his Ph.D. Degree in 1995, he joined the Toxicology Division at Wright-Patterson Air Force Base as a National Research Council Research Associate. At Wright-Patterson, he explored the application of biologically-based dose-response models to developmental toxicity by conducting research on the maternal-fetal pharmacokinetics of the prototypical teratogen, retinoic acid, and its ability to induce limb malformations and cleft palate in the developing mouse. Dr. Warren also served as a co-investigator on a project that examined the cardiovascular and ocular teratogenicity of the common groundwater contaminant, trichloroethylene, and its metabolites. He co-chaired the session entitled "Methods to Detect Developmental Toxicants" at Wright-Patterson's annual toxicology conference in 1997. While still a Research Associate at Wright-Patterson, Dr. Warren envisioned and co-authored two funded research proposals on the immunotoxicity of ammonium perchlorate and JP-8 jet fuel. He routinely participated in the conduct and interpretation of these research projects, both of which were conducted at the Medical University of South Carolina. Data from his perchlorate research were requested by the U.S. EPA and utilized as part of the Agency's toxicity evaluation.
Dr. Warren joined the staff of Toxicology, Ecology, Research and Risk Assessment (TERRA, Inc.) in November 1997 where he routinely evaluated the toxicology and theoretical risks associated with environmental chemicals and provided strategic, toxicological support to clients. His broad training and experience in industrial hygiene, epidemiology and public health, and toxicology were of particular value as he was frequently called upon to evaluate causal associations between both occupational and environmental chemical exposures and a host of cancer and non-cancer toxicities in individuals as well as populations. His consultancies involved virtually every chemical class, from halogenated solvents to organochlorine compounds and heavy metals. He is well versed in risk assessment procedures and has conducted numerous site-specific exposure/risk assessments and evaluated the risk assessments of others. He has created comprehensive toxicity profiles for numerous chemicals and assessed the scientific merits of toxicity constants established by state and federal agencies, and in some cases, generated alternative toxicity constants. In 1998, Dr. Warren was selected by the U.S. EPA's National Center for Environmental Assessment to provide a written review of the completeness and accuracy of contractor-generated reports on the toxicity of a selected group of drinking water disinfection byproducts.
In August 2002, Dr. Warren assumed a full-time position as Program Director, Environmental Health Science, at the University of South Carolina Beaufort (USCB). Shortly thereafter, he was selected by The National Center for Environmental Health, Centers for Disease Control and Prevention/Agency for Toxic Substances and Disease Registry as one of about 70 "emerging leaders" in Environmental Public Health from across the U.S. At USCB, Dr. Warren is responsible for the conduct of field- and laboratory-based research in environmental and human health risk assessment, with the focus of late being in support of the U.S. military's efforts to ensure the environmentally sustainability of its small-arms firing and air-to-ground bombing ranges. His applied research productivity at USCB is unprecedented, supported by nearly 4 million dollars in extramural funding to date. He serves as Founding Director of the University's Water Quality Laboratory, was instrumental in establishing a role for USCB in Beaufort County's quality of life indicators project, and provided instructional support to the nursing and early childhood education degree programs for a decade. He conceived the University's Heath Promotion major, authored the new program proposal that initiated its path toward approval by the South Carolina Commission on Higher Education, and currently supports it by teaching multiple courses within the curriculum. He also conceived and directs an ongoing effort to collect, analyze, and report body mass index (BMI) data on every 3rd-, 5th-, and 8th-grade student in the Beaufort, Jasper, and Hampton County School Districts. Most recently, these BMI data were instrumental in securing a $50,000 grant from the Transdisciplinary Collaborative Center for Health Disparities Research at the Morehouse School of Medicine for the purpose of exploring associations between student attributes and food choice in the racially and socioeconomically disadvantaged school district of Jasper County, SC. Dr. Warren was the principal author of the grant proposal and will serve as Co-PI on the project. Dr. Warren routinely serves as a technical resource to local, state and federal officials on a broad spectrum of environmental health-related matters. For example, he co-authored the report entitled, "Human Health Risk Assessment for Activities at Nellis Dunes Recreation Area, Las Vegas, NV", that was submitted to the U.S. Department of the Interior, Bureau of Land Management, in September 2014. In summer 2017, he co-authored, for the fourth time, the chapter entitled "Toxic Effects of Solvents and Vapors" in the most recent edition of the highly regarded text, Casarett and Doull's Toxicology, The Basic Science of Poisons.
