Benjamin Fisher began his toxicology career in 1978 working with the Bureau of Radiological Health (now the Center for Devices and Radiological Health; CDRH) of the Food and Drug Administration (FDA) where his initial training focused on the assessment of ultrasound-induced developmental and behavioral toxicology. During his tenure at FDA, his training continued in mammalian teratology. Dr. Fisher attended the University of Maryland where he received his BS and Master’s in developmental biology. He received his PhD in developmental genetics from the George Washington University where his research utilized mammalian whole embryo culture to evaluate alterations in embryonic gene expression as biomarkers of exposure and toxicity and their utility in predicting skeletal anomalies. Dr. Fisher joined Covance Laboratories in 1998 where, as a Principal Scientist and Study Director Manager, he was responsible for the design, conduct, and interpretation of preclinical developmental and reproductive toxicology (DART) and juvenile toxicology studies. In addition, he provided oversight to the developmental and reproductive toxicology program at Covance-Vienna. Dr. Fisher returned to the FDA in 2010, as the Deputy Director of the Division of Biology, providing oversight to the toxicology programs within the Office of Science and Engineering Laboratories; CDRH.  He is currently the Director of the Division of Reproductive, Gastro-Renal, and Urological Devices within the Office of Device Evaluation; CDRH.  He is a member of the Society of Toxicology, the Teratology Society, and past President of the Mid-Atlantic Reproduction and Teratology Association (MARTA).
