Toxicologist Dr. John Bucher has been named associate director of the National Toxicology Program. He has been a part of the NTP for 24 years, most recently as deputy director of the Environmental Toxicology Program and chief of its Toxicology Operations Branch. He succeeds Dr. Allen Dearry, who served as acting associate director from January 2006 to June 2007.
NIEHS/NTP director Dr. David Schwartz praised Bucher as a scientist with "outstanding scientific credentials, an insightful vision for toxicological research and an in-depth knowledge of the NTP." Schwartz expressed his confidence in Bucher's ability to realize the goals of the NTP Vision and Roadmap for the 21st century, which the new associate director was instrumental in developing.
Bucher joined the NTP in September 1983 after completing his Ph.D. in pharmacology at the University of Iowa and a postdoctoral fellowship at Michigan State University. He has served as chief of the Toxicology Operations Branch for the past 11 years and deputy director of the Environmental Toxicology Program since 1995. He received his certification by the American Board of Toxicology in 1984.
During his tenure at NIEHS, Bucher has published more than 100 studies in peer-reviewed journals and played a key role in shaping the program's research and policies, including comprehensive studies of dioxin and dioxin-like chemicals, chemicals that mimic estrogens. More recently he has pioneered the field of manufactured nanomaterials. His leadership was important in the development of the NTP Center for the Evaluation of Risks to Human Reproduction.
"I look forward to working with our exceptionally talented staff and NTP partners to produce the quality data and scientific understanding necessary for the protection of public health and critical to the further evolution of the science of toxicology," said Bucher. -
