Stephen S. Ferguson, Ph.D.
Stephen S. Ferguson, Ph.D., is a chemist in the Molecular Toxicology and Genomics Group within the Biomolecular Screening Branch of the National Toxicology Program (NTP) Division. His primary role is to lead the development of more predictive in vitro assay approaches (e.g., in vitro liver models competent for xenobiotic metabolism in high throughput screening assays) that support identification of hazardous chemicals and exploration of mechanisms of toxicity (e.g. receptor activation). With a background in drug metabolism pathways, drug-drug interaction mechanisms (e.g., induction of clearance pathways), and various in vitro assay systems, Ferguson supports the identification of in vitro approaches that diversify the ‘biological space’ for genomics platforms and provide more physiologically-relevant model systems for in vitro toxicology research. Ferguson also has an interest in understanding the quantitative relationships between in vitro responses (e.g., AC50) at the cellular and molecular level and translating these data to in vivo outcomes and environmental exposure levels.
Before joining the Biomolecular Screening Branch, Ferguson led the ADME/Tox research program at Life Technologies (formerly CellzDirect) where his group investigated and developed in vitro tools for hepatic biology, drug clearance, and drug-drug interaction pathway research. Ferguson also has a background in contract research management serving for multiple years as a Study Director on numerous non-clinical pharmaceutical research studies.
Ferguson received a B.S. in chemistry from North Carolina State University and a Ph.D. in chemistry (bioinorganic chemistry with a minor in biotechnology) from North Carolina State University.
