Paul Foster, Ph.D., is the Acting Chief of the Toxicology Branch and Deputy Director of the NTP's Center for the Evaluation of Risks to Human Reproduction (http://cerhr.niehs.nih.gov/) at the National Institute of Environmental Health Sciences in Research Triangle Park, North Carolina. His recent research is focused on investigating the mechanisms of environmental chemical and drug effects on reproductive development. Prior to joining NIEHS in 2002, he was the director of the research program in endocrine, reproductive and developmental toxicology at the CIIT Centers for Health Research. He joined CIIT in December 1995 after a 13-year career at Zeneca’s (formerly Imperial Chemical Industries) Central Toxicology Laboratory in Cheshire, England, where he was head of Reproductive and Developmental Toxicology.
Foster's research interests include the understanding the potential human health effects of environmental endocrine disruptors (particularly antiandrogens); mechanisms of testicular toxicity; the study of early testicular Leydig cell dysfunction induced by chemicals as a prelude to hyperplasia and tumors and the toxicokinetic and dynamic parameters affecting the induction of reproductive and developmental toxicity. He also has a broad interest in risk assessment issues in these areas and currently serves as the NTP’s senior discipline expert in Reproductive and Developmental Toxicology.
Foster was presented with the European Society of Toxicology's young scientist award in 1988 for his work on testicular toxicity and the Society of Toxicology's Reproductive and Developmental Toxicology specialty section award for best paper published in Toxicological Sciences in 2001 and 2004. He has served on numerous national and international advisory committees (EPA, WHO, IPCS, ECETOC, OECD, INSERM, MRC, NRC/ NAS, SETAC) dealing with reproductive toxicology and endocrine disruption. He also holds an adjunct appointment at North Carolina State University.
Foster is a member of a number of learned Societies dealing with toxicology and reproduction and is a former Chair and member of the Continuing Education Committee (1996-1999) and a Past President of the Reproductive and Developmental Toxicology specialty section of the Society of Toxicology (1997-2001). He has served on the editorial boards of Reproductive Toxicology, Birth Defects Research: Developmental and Reproductive Toxicology and as an Associate Editor of Toxicological Sciences. Foster is the author or co-author of over 100 peer-reviewed publications and book chapters and numerous regulatory study reports.
