What will I learn?

The field of toxicology is focused on developing improved ways to identify and reduce the harmful effects of chemical, physical, and biological agents at all levels of biological organization, from molecules to humans to complex ecosystems. This Master of Science degree in Environmental or Applied Toxicology trains students to identify, understand, and analyze toxic agents and their effects on human health and the environment. The curriculum includes courses in the supporting sciences of biostatistics and epidemiology, as well as foundational courses in exposure science and environmental health. Additional courses provide in-depth training in risk assessment and the fundamentals of toxicology, including organ system toxicology and the effects and mechanisms of toxicity of a wide range of toxic agents. Students earning an MS in Environmental or Applied Toxicology are well prepared to develop, interpret and utilize toxicological data to solve environmental health problems.

Degree options

This degree offers two distinct options. The MS in Environmental Toxicology is a 2-year degree that requires a thesis as a culminating experience. The MS in Applied Toxicology is an accelerated 5-quarter degree that requires and project as a culminating experience.

MS in Applied Toxicology

The 5-quarter, 15-month accelerated MS in Applied Toxicology degree option was developed for students looking for training in the practice of toxicology in order to be able to compete for jobs in private industry, federal, state or local government agencies, or academic institutions that require an MS degree. Students in this degree option complete the same course requirements as students in the MS in Environmental Toxicology, but conduct a supervised field study project at a training site (e.g., Region 10 EPA, NOAA, Public Health Seattle & King County, Veritox, and local biotechnology companies) during summer quarter of their first year instead of writing a research thesis as a culminating experience.
