Expert has over 25 years’ experience conducting environmental investigations and risk assessments for evaluating impacts to human health, property, and ecological receptors. His expertise focuses on the fate and transport of environmental contaminants, human health risk, exposure assessment, and ecological restoration. Expert has evaluated and modeled emissions from oil spills, landfills, boilers and incinerators, process stacks, storage tanks, confined animal feeding operations, industrial, military and agricultural sources, unconventional oil drilling operations, and locomotive and construction engines. His project experience ranges from monitoring and modeling of pollution sources to evaluating impacts of pollution on workers at industrial facilities and residents in surrounding communities. Expert has also successfully modeled exposure to contaminants distributed by water systems and via vapor intrusion.

Expert has investigated and designed remediation programs and risk assessments for contaminated sites containing lead, heavy metals, mold, bacteria, particulate matter, petroleum hydrocarbons, chlorinated solvents, pesticides, radioactive waste, dioxins and furans, semi- and volatile organic compounds, PCBs, PAHs, creosote, perchlorate, asbestos, per- and poly-fluoroalkyl substances (PFOA/PFOS), unusual polymers, fuel oxygenates (MTBE), among other pollutants. Expert also has experience evaluating greenhouse gas emissions from various projects and is an expert on the assessment of odors from industrial, locomotive and agricultural sites, as well as the evaluation of odor nuisance impacts and technologies for abatement of odorous emissions. As a principal scientist, Expert directs air dispersion modeling and exposure assessments. He has served as an expert witness and testified about pollution sources causing nuisance and/or personal injury at sites and has testified as an expert witness on numerous cases involving exposure to soil, water and air contaminants from industrial, railroad, agricultural, and military sources.

Expert may consult nationally and internationally, and is also local to the following cities: Los Angeles, California - Long Beach, California - Santa Ana, California - Anaheim, California - Riverside, California - Bakersfield, California - Glendale, California - Huntington Beach, California - San Bernardino, California - Oxnard, California

Additional Experience

Expert Witness Experience
He has been involved in numerous U.S. state and federal court cases. Some of which involve groundwater modeling, consolidated groundwater data, landfill fire, evaluating the montmorillonite clay deposit, hydrocarbon exposure, multimillion gallon oil spill, contaminated oil field, nuisance case, air emissions among numerous others.

Most Recent Litigation Support: Serving as expert in catalyst release and refinery emissions cases. One case settled regarding worker exposure, but ongoing litigation remains involving ~21,500 plaintiffs who have health claims and are seeking remediation from chemicals released from BP facility.

Serving as expert investigating hydrocarbon exposure and property damage for ~600 individuals and ~280 properties in CA, where homes were constructed above a large tank farm formerly owned by Shell. Most Recent Risk Assessment and Modeling: Prepared air dispersion model for a proposed state-of-the-art enclosed compost facility. Developed odor detection limits to predict 1, 8, and 24-hour off-site concentrations of sulfur, ammonia, and amine as well as prepared a traffic analysis.
