Barbara J. Petersen, Ph.D., M.P.H.

Dr. Petersen is internationally recognized for her expertise in exposure assessment methodology, functional food safety and efficacy evaluations, food consumption profile modeling, and applications of Monte Carlo techniques to risk assessments for chemicals including contaminants, pesticides, and nutrients. Dr. Petersen is also a specialist in addressing regulatory issues involving exposure and risk assessments including FDA, EPA International and California issues. She has provided specialized expertise in developing compliance procedures for heavy metals in toys, dishes, food and other consumer products. Dr. Petersen has pioneered the technical methods for incorporating information about dietary practices, actual agricultural practices and commercial food processing technologies into regulatory science issues. Dr. Petersen has successfully applied these approaches to develop software that maximizes the utility of data and provides realistic risk assessments that allow the user to understand the sources of potential exposure. Applications include FQPA compliance, regulatory strategies for existing products, intake calculations to support new pesticides, GRAS self affirmations and preparation of food additive petitions, nutrition labeling justifications, new food product designs and marketing strategies, and product stewardship program designs.

Dr. Petersen has directed the design and conduct of numerous statistically based market basket studies. These studies were designed for different purposes, including acute and chronic assessments for pesticides, compliance assessments under Proposition 65, and market research.

Dr. Petersen served on the EPA Science Advisory Board’s Integrated Exposure Committee and as an Expert Advisor to WHO/FAO for several session of JECFA and for numerous consultations on risk assessment. Also she served as Principal Investigator for the National Cancer Institute's International FOODBASE project, a major effort to collect and computerize descriptive and summary information on food consumption surveys conducted in more than 40 countries. Dr. Petersen has provided statistical support to FDA's Center for Food Safety and Nutrition, including developing criteria for evaluating nutrition databases, and specifically for the International Interface Standard for food databases and to EPA's Office of Research and Development. Dr. Petersen expanded Novigen's (now Exponent) expertise in aggregate/integrated exposure assessment to refine the treatment of residential exposure information and in developing new methods to conduct food safety risk assessments for microbiological contaminants. She has been a faculty member in risk assessment training programs for government scientists in the EU, Thailand, the US and China.

Expert to the WHO Nutrition group for Global Monitoring and a special WHO/FAO consultation on acrylamide. Conducted risk assessments for populations in the United Kingdom, Germany, Canada and other European Union (EU) countries.

Environmental Modeling: Designed, developed and installed exposure modeling projects, including major and innovative conversion of the results of food consumption surveys to forms compatible with US EPA, FDA and California EPA regulatory mandates and models and systems to assess exposure to contaminants from water. Evaluation of compliance for dietary contributions under California regulations. Conducted more than 5000 exposure/risk assessments for private and government clients.

National Food Survey Design: Responsible for directing the statistical design, field collection and analysis of more than ten national food monitoring studies, including database design for automated data collection and analysis.

Compliance and Regulatory Assessments: Twenty six years of experience producing strategies and technical support to corporate clients for assessing compliance with state and federal regulations product safety, litigation, and vulnerability assessments. (Developed exposure assessment tools for the California government's risk assessment mandate.)

Pesticide Usage Research: Directed local and national surveys of pesticide usage, including pesticide use on California tomatoes (fresh market and processed), celery, citrus, and all U.S. apples. Worked with farmers and their associations to design, implement and interpret surveys to quantify pesticide use practices. Developed procedures for quantifying the food byproducts used in animal feeds and for assessing pesticide levels in those feeds. Directed the utilization of federal and state pesticide usage data for improving risk assessments.

Proposition 65: Exposure and intake modeling to evaluate compliance with Proposition 65.

Dietary Exposure Evaluation Modules (DEEM™): Designed and developed modules of the DEEM-US and DEEM-United Kingdom Systems including:

· Cumulative and aggregate intake and exposure assessments
· Ingredient analysis options
· Nutrient analysis options
· Recipe modification module that allows the user to assess the impact of changes in formulations
· User-friendly menus
· Contaminant analysis module
· Food additive analysis options
· Subgroup analysis options, including menus for user-defined subgroups and income subgroups
· Customized system upgrades to accommodate user requests
· Monte Carlo assessments

Joint Distribution Methodology: Designed a computerized adaptation of Monte Carlo analysis for computing the probability of exposure to food contaminants and nutrients that now provides the basis for DEEM™ and Calendex™.

Nutrition Labeling: Criteria for the design of nutrient databases and related issues.

Twenty years' experience as the Corporate Officer for technical direction of Food and Exposure Assessment projects and as the Principal in charge of Novigen (and TAS) business and operations. As Corporate treasurer, developed and directed cost efficiency control procedures, personnel policy and procedures, and corporate financial controls.
