Toxicology for Human Risk Assessment
The Toxicology for Human Risk Assessment Master of Science program at Johns Hopkins University offers a comprehensive academic and research experience focused on evaluating chemical exposures and their potential impact on human health. Over two years of full-time, on-campus study, students gain expertise in toxicological sciences, environmental health, exposure modeling, and public health risk communication. The curriculum emphasizes molecular mechanisms, dose-response assessment, regulatory toxicology, and human health protection, equipping graduates to critically assess toxic agents in occupational, environmental, and consumer contexts.
Through a multidisciplinary lens, the program integrates biology, chemistry, epidemiology, and risk assessment methodologies, allowing students to explore how toxic substances interact with biological systems. Faculty members with backgrounds in both research and regulatory practice guide students through laboratory work, case studies, and risk evaluation exercises. Emphasis is placed on the interpretation of toxicological data, design of exposure studies, and the application of risk frameworks to inform policy. By combining quantitative modeling, toxicokinetics, hazard identification, and science-based judgment, the program prepares graduates for professional roles at the interface of science and public health decision-making.
