Kenneth T. Bogen, DrPH, DABT

Dr. Bogen has nationally recognized expertise in risk assessment for environmental carcinogens and in related exposure, PBPK, dose-response and uncertainty analysis. Before joining Exponent’s Health Sciences Group in 2007, he led experimental, epidemiological and mathematical-modeling research on health risks posed by environmental exposures to chemicals and ionizing radiation, as a University of California environmental scientist for 20 years at Lawrence Livermore National Laboratory.

He also has been a consulting expert for cancer-risk litigation involving environmental, dietary and consumer-product exposures. He helped develop methods now widely used in environmental risk analyses involving quantitative characterization of joint uncertainty/variability, PBPK modeling, and mechanistic dose-response analysis for volatile-solvent, carcinogenic and cytotoxic chemicals.

Dr. Bogen served as a Member of the National Academy of Sciences/National Research Council (NRC) committees that issued Science and Judgment in Risk Assessment (1994) and Review of the Army’s Technical Guides on Assessing and Managing Chemical Hazards to Deployed Personnel (2004); served as expert panelist at the NRC Standing Committee on Risk Analysis Issues and Reviews, Workshop on Uncertainty in Cancer Risk Based on Bioassay Data (June 5, 2007); chaired the Metabolism and Mode of Action Panel, Naphthalene State of the Science Symposium (NS3), Monterey, CA (October 9–12, 2006); and chaired the U.S. Consumer Product Safety Commission’s Chronic Hazards Advisory Panel on Diisononyl Phthalate (DINP) (2000–2001). Dr. Bogen also authored and continues to develop RiskQ computer software (a University of California-licensed Mathematica® package) for biostatistics, stochastic modeling, and uncertainty analysis, authored Uncertainty in Environmental Health Risk Assessment (Garland, New York, 1990), and has authored or coauthored more than 100 reports and publications in peer-reviewed scientific journals.

Dr. Bogen served as President (1995) and Councilor (2004–2006) of the Northern California Chapter of the Society for Risk Analysis.
