Ms. Callan Krevanko is a Managing Scientist in Exponent's Health Sciences practice. She is dually trained in environmental epidemiology and exposure science and has more than ten years of scientific consulting and research experience. Her work focuses on characterizing exposures and health risks across occupational, consumer product, and community settings. She has evaluated exposures to legacy and emerging chemicals including asbestos, bisphenol A (BPA), ethylene oxide (EtO), per- and polyfluoroalkyl substances (PFAS), titanium dioxide (TiO₂), silicon dioxide (SiO₂), volatile organic compounds (VOCs), particulate matter, and bioaerosols. She has also supported regulatory compliance for chemicals in consumer and cleaning products, such as 1,4-dioxane, BPA, and benzene.

Ms. Krevanko specializes in respiratory exposures and work-related lung disease, combining detailed exposure assessment with epidemiologic analyses in worker populations. She has evaluated human health risks using personal and area exposure monitoring, critical reviews of the scientific literature, and analyses of population-level health and exposure data. Her peer-reviewed publications span topics including occupational hypersensitivity, cosmetic talc, mesothelioma, hair relaxers, and female reproductive health outcomes.

- Managed human health risk assessments for bisphenol A (BPA), benzene, PFOA, and PFOS under Proposition 65.
- Assessed human health risk from exposure to per- and poly-fluorinated substances (PFAS) in synthetic sports turf and residential carpets.
- Managed epidemiological evaluations on cosmetic talc exposure and mesothelioma.
- Managed human health risk assessment for asbestos in friction products.
- Measured workers' exposure to VOCs in industrial and office settings.
- Assessed worker's exposure to titanium dioxide (TiO2) and silicon dioxide (SiO2) during the use of paints and coatings.
- Managed assessment of non-occupational exposure to ethylene oxide (EtO).
- Measured occupational exposure to bioaerosols and VOCs in agricultural settings.
- Provided industry guidance to support compliance with 1,4-dioxane regulations for cleaning products.
- Conducted exposure simulation study to evaluate exposure to asbestos in historical products.
