International Isocyanate Institute

After an internship in an industrial toxicology laboratory, Dr. Anne H. Chappelle enrolled in the pharmacology/toxicology PhD program at the Philadelphia College of Pharmacy and Science (now University of the Sciences), focusing on upper respiratory tract/nasal toxicity. The next 19 years were as an industrial-chemical/regulatory toxicologist in the Philadelphia area (Huntsman Polyurethanes, Rohm & Haas, Sunoco). While the chemical dossiers may have varied, the key functions did not: provide expert chemical evaluations incorporating transparent and rigorous scientific principles, and tailored communications for the appropriate audience (consumer, regulator, CEO, worker, etc.). More recently, Dr. Chappelle has used these skills as a consultant (Chappelle Toxicology Consulting, LLC) helping small and medium sized companies interpret the science to meet regulatory requirements, and a Staff Toxicologist (International Isocyanate Institute) providing strategic management and technical expertise in diisocyanate toxicity.

Dr. Chappelle has been involved with the Mid-Atlantic Regional Chapter (MASOT) since graduate school, first serving on the Membership Committee, where she helped lead efforts to maintain the membership database, produce a directory, and develop strategies and tools to recruit members. She served on the MASOT’s Executive Council, as a Student Councilor, Councilor, and Treasurer, supporting efforts to maintain a strong and diverse chapter that could offer diverse programming and networking opportunities maximizing the value of membership.
