Dr. Amy Madl is a toxicologist with over 15 years of experience in the sampling and analysis, toxicology, exposure, and risk assessment of airborne chemicals.  She earned a BS in Biochemistry and an MS in Pharmacology/Toxicology.  She is board-certified in toxicology and has focused her academic and consulting experience in the field of inhalation toxicology.  Dr. Madl also specializes in occupational toxicology, air pollution, quantitative exposure reconstruction, and historical state-of-the-science assessment.  She has expertise in quantitative exposure and risk assessment of airborne compounds in occupational and residential settings, as well as in safety evaluation of contaminants associated with medical devices and consumer products.  Her experience includes investigating the health effects of exposure to a variety of compounds, including diesel exhaust, PM2.5, beryllium and other metals, benzene, oxidant gases, petroleum products, and asbestos, as well as irritants and sensitizers.  Notable contributions that Dr. Madl has made to the field of occupational toxicology includes research on the exposure-response relationship between airborne beryllium and the prevalence of beryllium sensitization and chronic beryllium disease among manufacturing workers, characterization of historical exposures to airborne asbestos during gasket, packing, and brake repair activities, and investigation of consumer and industrial exposures to benzene from engine exhaust and solvent handling tasks.  Her recent research interests have focused on the toxicological effects of inhaled nanoparticles (i.e., carbon nanotubes), in which the patterns of regional and local cellular injury, particle fate and transport, and expression of markers of oxidative stress are evaluated in the lungs of animals exposed to inhaled engineered nanoparticles with different chemical and size compositions.  Dr. Madl has published over 70 abstracts, book chapters, and peer-reviewed papers on various occupational and environmental exposure, toxicology, and risk-related topics.
