Dr. Brent Kerger is a Principal Scientist in Exponent's Health Sciences Center for Toxicology and Mechanistic Biology.  A board-certified toxicologist, Dr. Kerger specializes in the study of environmental chemical fate and transport, exposure assessment, pharmacokinetics, and adverse human health effects.  He has over 38 years of experience conducting and managing laboratory, field, and clinical studies of exposure, toxicology, epidemiology, and disease causation analysis.  He provides scientific and strategic consultation regarding regulatory and litigation matters including 29 years of environmental chemistry and toxicology expert witness experience.  He has in-depth expertise regarding asbestos, talc, dioxins and furans, PCBs, PAHs, chlorinated solvents, benzene and petroleum products, irritant gases, pesticides, flavoring chemicals, and heavy metals.  

He has over 35 years of experience as a professional toxicologist focusing on:

  • Multi-disciplinary research in fate/transport, exposure assessment and toxicokinetics;
  • Design and implementation of studies to characterize exposure/dose and toxicity;
  • Human health and ecological risk assessments including complex indirect pathways;
  • Evidence-based approaches for analysis of epidemiologic studies; and
  • Disease causation analysis using the Hill Criteria and alternative cause assessment.

A board-certified toxicologist since 1994, Dr. Kerger has extensive experience in evaluating scientific issues involving claims of chemical causation or increased risk of diseases in humans in regulatory and litigation settings.  He has thoroughly researched key toxicological issues surrounding human exposures to a broad range of chemicals and mineral dusts.  Dr. Kerger guides the optimized research capabilities and access to resources (expertise and information) that promote an integrated, multi-disciplinary perspective to addressing scientific issues.  He has designed and implemented a variety of field studies, laboratory studies, and clinical studies aimed at characterizing chemical exposure and toxicity.  He has published numerous articles in peer-reviewed journals on chemical toxicity, physiologically-based pharmacokinetic modeling, Monte Carlo uncertainty analysis, evidence-based analysis, and innovative exposure and risk assessment techniques.
