Master of Science in Toxicology Master of Science in Toxicology [1-year]

The Master of Science in toxicology is a one- to two-year program designed to prepare students for professional school, pursuit of a Ph.D., or careers in industry, government, and consulting. It focuses on the effects of chemicals and other potentially harmful agents on the health of the environment, humans, and animals. Upon completion of coursework, students in this program have the option of either taking a comprehensive exam or completing a professional paper with the consent of a faculty member.

Students enrolled in the 1-year master’s program can switch to the thesis option after their first semester in the program once they have secured a faculty sponsor.
