An environmental and atmospheric sciences expert with more than 35 years of experience, he specializes in air quality compliance, atmospheric dispersion modeling, pollutant transport, environmental monitoring, and odor impact assessment. His expertise includes the movement and dispersion of airborne pollutants across complex terrain, overwater and coastal environments, and urban settings, as well as environmental compliance matters involving industrial emissions, hazardous materials, and nuisance odor conditions. He has provided consultation and deposition testimony for more than 10 years in legal and regulatory matters involving meteorology, atmospheric dispersion, air pollution, and odor impacts.

Throughout his career, he has designed and implemented more than 80 atmospheric monitoring networks and air measurement programs involving toxic chemicals, volatile and semi-volatile organic compounds, metals, particulate matter, odorous compounds, and criteria pollutants. His work has included meteorological monitoring, tracer gas analysis, remote sensing studies, overwater dispersion investigations, hazardous waste monitoring, greenhouse gas regulatory analysis, and urban dispersion modeling for emergency response and environmental risk assessment. Additional experience includes homeland defense-related studies involving chemical and biological agent simulations, building infiltration analysis, and crisis management modeling.

In addition to technical consulting, he has held executive leadership positions within multiple environmental consulting organizations, directing multidisciplinary teams responsible for air quality, environmental compliance, safety compliance, and risk management programs. He has participated in greenhouse gas rulemaking and cumulative impact assessment initiatives involving the California Air Resources Board and local air quality agencies, while also serving on air quality hearing boards and technical working groups. His credentials include Qualified Environmental Professional and Registered Environmental Assessor designations, along with graduate training in meteorology and undergraduate training in physics. Professional affiliations include the Air and Waste Management Association, American Meteorological Society, American Society of Mechanical Engineers, and National Defense Industrial Associations.
