Josh D. Butler, Ph.D. - ExxonMobil Biomedical Sciences, Inc.

Dr. Butler joined Exxon Mobil Biomedical Sciences, Inc. as an Environmental Scientist in June, 2008. He is currently involved in laboratory operations for ExxonMobil Biomedical Sciences Inc., in Annandale, NJ. Dr. Butler holds a B.S. in Environmental Sciences, and M.S. in Aquatic Biology from East Stroudsburg University. Additionally, he received a Ph.D. in Ecotoxicology from Rutgers University. He has focused most of his energy in the field of environmental toxicology studying toxic effects of non-polar organic compounds on freshwater and marine vertebrates, invertebrates as well as sediment and terrestrial organisms. His early work in aquatic toxicity testing included the validation of fish embryo toxicity test as an alternative to the whole fish acute toxicity test using polycyclic aromatic hydrocarbons. Subsequent research focused on the extension of the fish embryo test to a chronic early life stage test to distinguish sensitivity differences between life stages. Currently, Dr. Butler manages the environmental toxicology and fate laboratory, coordinating acute and chronic saltwater, freshwater, sediment and terrestrial toxicity tests and biodegradation studies. Dr. Butler has been an author on several publications covering topics such as passive dosing, passive sampling, phototoxicity, dispersant biodegradation, bioaccumulation and toxicity of poorly water soluble organic chemicals in freshwater, saltwater, sediment and soil.

He has a passion for sound science and is committed to maintaining the excellent reputation that SETAC-HDC has earned over the last several decades.

Dr. Butler is an avid outdoorsman, involved in just about anything to do with water and woods. He lives in the Lehigh Valley with his wife Casey and two kids, Molly and Maggie. He enjoys people, reading/learning, exercise, and family time.
