Steve is Chief of the Analytical Chemistry Division, one of six Divisions within the Chemical Science and Technology Laboratory (CSTL) at the National Institute of Standards and Technology (NIST). The Analytical Chemistry Division consists of approximately 100 professional staff and serves as the Nation's reference laboratory for chemical composition measurements and standards. The Standard Reference Materials (SRMs) and measurement services provided by the Analytical Chemistry Division impact U.S. industrial productivity; assure equity in trade; and provide quality assurance of measurements used for assessing and improving public health, safety, and the environment. Steve began his career at NIST (then the National Bureau of Standards) in 1976 as a research chemist involved in the development of liquid chromatography methods for the determination of organic contaminants. During his career at NIST, Steve’s research efforts have focused on trace organic analysis including: (1) the development of chromatographic methods for the determination of organic contaminants, e.g., polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls, and chlorinated pesticides, in environmental matrices such as sediment, tissue, and air particulate matter; (2) the development of Standard Reference Materials (SRMs) for trace organic constituents in environmental, clinical, food, and dietary supplement matrices; (3) investigations of chromatographic separation mechanisms and chromatographic selectivity for PAHs and related compounds; and (4) the development and implementation of environmental specimen banking procedures. He has authored or co-authored over 290 technical publications and presented over 220 talks describing these activities at national and international scientific meetings and universities. Awards:
