  • Course Learning Objectives

    Upon successfully completing this course, students will be able to:

    • Create, document, and describe a probabilistic exposure assessment model
    • Recognize and evaluate information gaps in risk models and the assumptions used to fill them
    • Describe the influence of variability and uncertainty on risk estimates
    • Critique risk analyses
  • Course Description
    Introduces students to a variety of quantitative and qualitative methods used in hazard identification/characterization, exposure and dose-response assessment for chemical and microbial risk assessments. Students gain experience with selected methods through the assignments including probabilistic exposure assessment modeling, qualitative weight-of-evidence evaluation, and guided review and critique of existing risk analyses. Students learn to identify and evaluate assumptions used to bridge data gaps and to conceptualize and communicate variability and uncertainty. Guest speakers discuss current and emerging issues in chemical and microbial risk assessment and management.

  • Instructor Bio

    Dr. Mary Fox is Assistant Professor in the Department of Health Policy and Management and Co-Director of the Risk Sciences and Public Policy Institute at the Johns Hopkins Bloomberg School of Public Health.  She received a BS in Biology from the State University of New York at Albany, an MPH in Environmental Studies from the University of Rochester School of Medicine and Dentistry, and a PhD in Environmental and Occupational Health Policy from the Johns Hopkins Bloomberg School of Public Health.  Dr. Fox received a AAAS Post-doctoral Fellowship in Risk Policy with a posting in USDA’s Office of Risk Assessment and Cost-Benefit Analysis.  Her post-doctoral project focused on evaluating the first cumulative risk assessment for organophosphate pesticides.  Dr. Fox spent one year as a program officer at the National Academy of Sciences in the Board on Environmental Studies and Toxicology where she staffed the Committee on Health Risks of Perchlorate Ingestion and the Subcommittee on Emergency and Continuous Exposure Guidance Levels for Selected Submarine Contaminants. Since returning to Johns Hopkins, Dr. Fox’s research has focused on quantitative human health risk assessment as a part of environmental policy making, particularly approaches to cumulative and chemical mixtures risk assessment.

    Dr. Fox has served on two National Academy of Sciences panels, the IOM Committee on Long-term Health Consequences of Exposure to Burn Pits in Iraq and Afganistan and the NRC Committee on the Health Risks of Phthalates.  She has advised EPA on several topics including fluoride exposure and approaches to cumulative risk assessment for phthalates.  Dr. Fox began her public health career conducting community health studies around hazardous waste sites as a Research Scientist in the New York State Department of Health.
