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 30 years of experience in the design, conduct, and synthesis of marine environmental monitoring and chemical forensic programs. He is recognized for his extensive knowledge on the chemical processes associated with petroleum in the environment including weathering and biodegradation of oil and dispersant application. His experience includes work on many oil spills, including the Deepwater Horizon, Exxon Valdez, Shell Gasconade River, Marathon Newton Lake, Haven, North Cape, Julie N, New Carissa oil spills, in addition to the Baffin Island oil spill study and the Shell Martinez Bay oil spill investigation. Mr. Brown has developed new analytical and interpretive techniques for the chemical fingerprinting and allocation of hydrocarbon contamination in the environment.
Mr. Brown has also 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 designing and managing multidisciplinary 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.
