Jack Bishop, Ph.D., is a geneticist in the Toxicology Branch of the National Toxicology Program at the National Institute of Health’s National Institute of Environmental Health Sciences (NIH/NIEHS). Bishop came to the NIEHS in 1985 from the U.S. Food and Drug Administration’s National Center for Toxicological Research in Jefferson, Arkansas where he spent 10 years investigating chemically induced mutagenesis in rodent germ cells. Prior to that, Bishop was a Research Geneticist at the U.S. Department of Agriculture’s Honeybee Breeding and Stock Center Research Laboratory in Baton Rouge, Louisiana.
Bishop is the Project Officer for the multi-generation reproductive toxicology contract used to evaluate reproductive and developmental toxicity of chemicals of interest to the National Toxicology Program (NTP). In addition to his duties as a Project Officer, he also conducts independent research studies of reproductive, developmental and genetic toxicity in rodent animal models as well as in human subjects. He provides genetic toxicology support for the NTP and serves as a scientific resources for the TOB and the ETP developing research plans and protocols to meet Program objectives.
Bishop has led the effort to develop biomarker assays for the NTP for the detection of genetic damage in rodent sperm, using fluorescence in situ hybridization (sperm-FISH) to identify and characterize mammalian germ cell mutagens. He also serves as a Topic Manager for extramural Small Business Innovative Research Contracts and Grants.
Bishop has over 30 years expertise in germ cell mutagenesis and environmental toxicology, with emphasis in reproductive, developmental and genetic toxicology, and has published over 60 scholarly publications in these areas. He has also given numerous invited presentations at national and international meetings. He is currently Treasurer and Executive Board Member of the most prestigious scientific society in his field, the U.S. Environmental Mutagen Society (EMS), and Past President of the regional EMS, the Genotoxicity and Environmental Mutagen Society.
He received a B.A. in biology/chemistry from McMurry College, Abilene, Texas, in 1967, an M.S. in zoology from Louisiana State University, Baton Rouge, Louisiana in 1970 and a Ph.D. in genetics from Louisiana State University in1974.
