Dr. Reiss is an environmental health scientist with expertise in risk assessment, exposure assessment, toxicology, environmental chemistry and fate, mathematical modeling, and applied statistics. He provides consulting services related to scientific issues associated with numerous environmental statutes and has expertise in both chemical risk assessment and air quality.
Dr. Reiss has conducted risk assessments, data analyses, probabilistic exposure modeling, and environmental exposure modeling for environmental agents, such as pesticides, industrial chemicals, and consumer product chemicals. He has conducted risk assessments for new and existing products.
Dr. Reiss is active in the application and development of quantitative methods in risk assessment. He is the developer of the Probabilistic Exposure and Risk assessment model for FUMigants (PERFUM), which is an air dispersion model designed to evaluate bystander inhalation exposure following fumigant applications. PERFUM is widely used by Environmental Protection Agency (EPA) and other public agencies for evaluating bystander risks for pesticide volatilization. He also leads the development of physiologically based pharmacokinetic (PBPK) models and has developed New Approach Methodologies (NAMs) to understand species differences in chemical toxicity. He has expertise in dose-response modeling and has experience with several dose-response software tools. He has published in the areas of human and ecological risk assessment, exposure assessment, dose-response, nutrition, and epidemiology.
Dr. Reiss is actively involved in several scientific societies, and he is a Past-President and Fellow of the Society for Risk Analysis (SRA), the leading scientific society devoted to the field of risk assessment. Dr. Reiss was the Managing Editor of Risk Analysis: An International Journal, the leading scholarly journal for risk analysis, from 2001 through mid-2008. He was the winner of the 2001 Chauncey Starr (early career) award from SRA. In 2018, he was awarded the Outstanding Practitioner Award from SRA.
