CTEH® Continues to Grow Toxicology Resources with Hiring of Particulate and Fiber Expert, Dr. Tom Hesterberg

The Center for Toxicology and Environmental Health (CTEH®) is pleased to announce the hiring of Dr. Tom Hesterberg as Senior Toxicologist for the company. Dr. Hesterberg brings over 24 years of toxicological experience (including diesel exhaust, asbestos and manmade fibers) to CTEH team. This hire reinforces our dedication to providing highly technical and highly responsive professionals to evaluate and develop solutions to a wide variety of human health and environmental issues.

Before coming on board at CTEH, Dr. Hesterberg spent 10 years at Navistar, Inc., the largest manufacturer of trucks and engines in the US, where he served as Director of Product Stewardship, Sustainability, and Environmental Health. At Navistar, Dr. Hesterberg oversaw the evaluation of the potential health, safety and environmental risks related to the use of diesel trucks and engines. Dr. Hesterberg has published over 100 papers in peer-reviewed journals on the potential health effects of chemicals and particles (including diesel exhaust particles) to which humans are exposed. He has served on numerous health assessment and toxicology review panels for government agencies, including the International Agency for Research on Cancer (IARC), the US Environmental Protection Agency, the California Air Resources Board, the National Toxicology Program, the Department of Energy, the German MAK Kommission, and the UK Medical Research Council.

In prior positions he served as a Director of Health, Safety and Environment and directed a research program to assess the potential carcinogenicity of man-made fibers, including fiberglass. Findings from the research program led to downgrading of some man-made fibers to “not classifiable as carcinogenic” by IARC.

Dr. Hesterberg has a BS in biology and an MS in physiology from UCLA, a PhD in toxicology from UC Davis, and an MBA from the University of Denver. He completed postdoctoral studies at the National Institute for Environmental Health Sciences (NIEHS).
