Professional Profile


Mr. Brown is responsible for overall program management and the technical supervision of environmental monitoring, analytical chemistry, and environmental forensics projects. Mr. Brown has over 25 years of experience in the design, conduct, and synthesis of marine environmental monitoring programs. His extensive experience on the chemical processes associated with petroleum in the environment includes work on the Baffin Island oil spill study, the Shell Martinez Bay oil spill investigation, Shell Gasconade River oil spill, the Marathon Newton Lake oil spill, the Exxon Valdez oil spill, the Haven oil spill, the Gulf War oil spill, the North Cape oil spill, the Julie N oil spill, the Kure oil spill, the New Carissa oil spill, and many others. Mr. Brown has developed new analytical and interpretive techniques for the chemical fingerprinting and allocation of hydrocarbon contamination in the environment. Mr. Brown has developed analytical and field techniques for a wide variety of matrices, including sediments, water, air, crude oil and refined petroleum products, oilfield production water, drilling fluids, animal tissues, and semi-permeable membrane devices (SPMDs). The chemical analyses of these matrices have included trace-level and forensic determinations of saturated and aromatic hydrocarbons, heterocyclic compounds, biomarkers (steranes and triterpanes), polychlorinated biphenyls (PCBs), chlorinated pesticides, and sterols. Mr. Brown has extensive experience in managing field programs and field sampling in the marine environment. He also has experience in the set up and QA/QC evaluation of mobile laboratory and fixed laboratory operations as part of environmental site investigations in the United States and the former Soviet Union.
