个人简介
Bill's research started with the measurement of organometals (of mercury, tin, and lead) in biological and water in marine environmental samples. The determination of nitroaromatic compounds in air samples and phenolic compounds in crude and shale oil followed. Methods for the measurement of fat soluble vitamins (E, K, and the isomers of A and β-carotene) in serum as well as the photoreactivity and electro-oxidation of retinol were another area of study. He was Co-PI for the first 3 years of the ongoing NCI-NIST Micronutrient Measurement Quality Assurance Program for these vitamins in sera. He has been quite interested in the chemistry and determination of reduced organic and inorganic compounds associated with marine water column and sediment anoxia. He was project manager for the investigation of the supercritical fluid extraction of environmental samples as part of the CSTL Consortium on Automated Analytical Systems (CAALS). For 20 years, he has done research into the forensic detection of gunshot and explosive residues from smokeless powder. The reactivity of wastewater components, including biological amines and pharmaceutical compounds with chlorine and chloramines has been an area of study. In the past 5 years, he has been the PI on a major Department of Homeland Security project to develop Standard Reference Materials and measurement technology for the detection of trace explosives including military and improvised compounds. The characterization, affinity, and impact of functionalized gold nanoparticles are also under current study.
