Research Toxicologist — Division of Biochemical Toxicology
Jeffrey Fisher, Ph.D.
Dr. Jeffrey Fisher is a research toxicologist in NCTR’s Division of Biochemical Toxicology. He was formerly a professor in the Department of Environmental Health Science, College of Public Health at the University of Georgia (UGA). He joined UGA in 2000 and served as department head of the Department of Environmental Health Sciences from 2000-2006 and director of the Interdisciplinary Toxicology Program at UGA from 2006-2010. Before this, he spent 25 years at the Toxicology Laboratory, Wright Patterson AFB, where he was principal investigator and senior scientist in the Toxics Hazards Division and technical advisor for the Operational Toxicology Branch. Dr. Fisher has 30 years of experience in physiological modeling and has trained graduate students and postdoctoral fellows on the concepts and application of physiological models. He was a visiting scientist at the Chemical Industry Institute of Toxicology in 1996 and at the NIOSH Taft Laboratory in 1999. During this time, he also served as an adjunct professor in the Department of Pharmacology and Toxicology at Wright State University. Dr. Fisher has published over 170 papers on pharmacokinetics and PBPK modeling in laboratory animals and humans.
Dr. Fisher has served on several national panels and advisory boards for the Department of Defense, the Agency for Toxic Substances and Disease Registry, the Environmental Protection Agency (EPA) and nonprofit organizations. He was a U.S. delegate for the North Atlantic Treaty Organization in Paris, France, charged with evaluating the potential impact of oil-well fires on community health. Dr. Fisher served on the International Life Sciences Institute Steering Committee that evaluated chloroform and dichloroacetic acid using proposed EPA Carcinogen Risk Guidelines. He is the past president of the Biological Modeling Specialty Section of the Society of Toxicology and has served as reviewer for several toxicology journals. Dr. Fisher also was co-principal investigator on a National Institutes of Health (NIH)-supported workshop on Mathematical Modeling at the University of Georgia in the fall of 2003. He was a member of the National Academy of Sciences Subcommittee on Acute Exposure Guideline Levels from 2004-2010 and a member of the Science Advisory Board for the EPA from 2007-2010. He is an ad-hoc member of the EPA Science Advisory Board and Science Advisory Panel for dioxin, perchlorate, and chlorpyrifos. He is a fellow of the Academy of Toxicological Sciences and an associate editor for Toxicological Sciences. Dr. Fisher has a bachelor's degree in biology from the University of Nebraska at Kearney, an master's degree in biology from Wright State University, and a Ph.D. in zoology/toxicology from Miami University.
Dr. Fisher's career research interests are in the development and application of pharmacokinetic and biologically based mathematical models to ascertain health risks from environmental, occupational, and foodborne chemicals. Recently he has become involved in the use of physiologically based pharmacokinetic (PBPK) models for pediatric drugs. Dr. Fisher’s chemical-toxicology modeling experience includes working with chlorinated and non-chlorinated solvents, hydrocarbon-based and synthetic fuels, pesticides, perchlorate, and Bisphenol A. He has developed PBPK models for use in:
- cancer risk assessment
- estimating lactational transfer of solvents
- understanding in utero and neonatal dosimetry
- quantifying the metabolism of solvent and fuel mixtures
- developing biologically motivated models for the hypothalamic-pituitary-thyroid axis in rodents and humans, including life stages and reproductive states.
Dr. Fisher is best known for his pioneering laboratory research and PBPK modeling of pregnancy and lactation to describe the influence of reproductive state and life stages on the dosimetry of the solvent trichloroethylene and its primary metabolites. More recently he is recognized for creating biologically based models to describe endocrine disruption of the thyroid system during development in the rat and human and their application in safety assessment.
Since arriving at FDA, Dr. Fisher has collaborated with scientists from other FDA centers interested in using models for pediatric populations, medical devices, in vitro to in vivo extrapolation, and safety assessments for chemicals. He is involved in EPA-directed virtual thyroid-modeling projects. Dr. Fisher is collaborating with FDA and EPA scientists, industry scientists, and academia scientists to construct a robust physiological description of the preterm infant born over a range of gestational ages. Preterm birth has been overlooked in the fields of toxicology and pharmacology. The preterm neonate PBPK model will be used for estimating drug dosage and exposure to chemicals used in baby products. Dr. Fisher will carry out modeling projects as proof-of-concept for in silico predictions and extrapolation of preclinical toxicology data in laboratory animals to humans. Species and life-stage extrapolation of pharmacodynamic models for diseases (e.g., hypothyroidism) will be completed over the next two years.
