Susan Chemerynski

Susan Chemerynski is an Associate Professor at Johns Hopkins University's Bloomberg School of Public Health, holding the Jacob I and Irene B. Fabriskant Chair in Health, Risk, and Society. She is affiliated with the Department of Health Policy and Management and the Environmental Health and Engineering department. Her research focuses on inhalation toxicology, respiratory health, and the health impacts of electronic nicotine delivery systems (ENDS) and tobacco products. She leads studies on aerosol dosimetry, nicotine pharmacokinetics, and the fate of inhaled substances in human respiratory tracts.

Chemerynski's work bridges environmental health, toxicology, and public policy. Her recent studies investigate ENDS aerosol dynamics in adolescents, cigarette puff fate modeling, and rodent inhalation toxicity of NNK and other tobacco constituents. She collaborates with the Risk Sciences and Public Policy Institute, applying computational models to assess inhalation exposure risks.

Her publications analyze ozone exposure mortality via meta-regression and propose mechanisms for acrolein-induced respiratory toxicity. She contributes to public health policy through evidence-based research on environmental pollutants and tobacco harm reduction strategies.
