Richard Reiss, Sc.D.

Principal Scientist

Chemical Regulation & Food Safety

Professional Profile


Dr. Reiss is an environmental health scientist with expertise in risk assessment, exposure assessment, 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 air quality and chemical risk assessment. He has conducted risk assessments, data analyses, probabilistic exposure modeling and environmental exposure modeling for environmental agents, such as pesticides, industrial chemicals, consumer product chemicals, and asbestos. He has conducted risk assessments for new and existing products.

Dr. Reiss is very 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 was favorably evaluated by a multidisciplinary expert panel assembled by Environmental Protection Agency (EPA), and is being used by EPA to evaluate the registration of new fumigant active ingredients and the re-registration of existing fumigant products. Generally, he has used a variety of mathematical models in conducting occupational and ecological risk assessments for pesticides and industrial chemicals; and performed statistical analyses, including dose-response modeling to evaluate chemical toxicity.

Dr. Reiss is actively involved in several scientific societies and he is the Past-President of the Society for Risk Analysis, 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 award from the Society for Risk Analysis. This award recognizes a risk analyst less than 40 years of age that has made major contributions to the field of risk analysis. Dr. Reiss was also a councilor in the Society for Risk Analysis (term 2005–2008). In 2010, he was elected a Fellow of the Society for Risk Analysis.
