Kenneth T. Bogen, Dr.P.H., DABT

Managing Scientist and consulting toxicologist in Exponent’s Health Sciences Center for Exposure Assessment and Dose Reconstruction (Oakland, CA) (2007–2017), with nationally recognized expertise in environmental health risk assessment and related exposure, pharmacokinetic, dose response, statistical, and uncertainty analysis. As University of California environmental scientist at Lawrence Livermore National Laboratory (LLNL), led experimental, epidemiological, and mathematical modeling research on health risks posed by environmental exposures to chemicals and ionizing radiation (1986–2007).

Consulting expert on quantitative exposure and health risk assessments addressing dose response, carcinogen risk, carcinogen mode-of-action, dermal absorption, toxicokinetics, physiologically based pharmacokinetic (PBPK), biologically based, toxicodynamic, and statistical modeling and data analysis, and related occupational, consumer-product, California Proposition 65, and groundwater issues. Authored/co-authored >100 related (including 3 award-winning) peer-reviewed scientific publications/reports, provides related expert, litigation-support (including expert deposition), regulatory evaluation, and technical-analysis services. Projects, publications, research, and services have addressed: asbestos, allergic contact dermatitis elicitation risks (e.g., from wearable technology product use), arsenic, benzene, captan, Cs-137, chromium, dermal exposure, 1,3-dichloropropanol, dibenzo[a,l]pyrene, diethanolamine, dimethoate, furfuryl alcohol, formaldehyde, hydrogen sulfide, lead, malathion, 3-methylchloropropanol, 4-methylimidazole, methyl isobutyl ketone (MIBK), methyl tert-butyl ether (MTBE), musks, b‑myrcene, naphthalene, nickel, chemical migration from paperboard packaging, PhIP and other cooked-meat carcinogens, phthalates, radionuclides, radon, transuranic elements (uranium, plutonium), and VOCs. Journal articles have also addressed worldwide terrorism casualty modeling; temporal fluctuation & spatial heterogeneity in atmospheric chemical dispersion and threat zone prediction/modeling; organophosphate PBPK models, methods, & applications; and environmental health risk management.

Member, 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); chaired the U.S. Consumer Product Safety Commission’s Chronic Hazards Advisory Panel on Diisononyl Phthalate (DINP) (2000–2001); chaired the Metabolism and Mode of Action Panel, Naphthalene State of the Science Symposium (NS3), Monterey, CA (2006); and 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 (2007). President (1995) and Councilor (2004–2006) of the Northern California Chapter of the Society for Risk Analysis (SRA); Chair-Elect and Chair of SRA Dose-Response Specialty Group (2016–2017). Winner, Wolfram Innovator Award 2020.
