MS Course Requirements | Minor in Toxicology | Current Students and Recent Graduates

All MS students admitted into the program on the research paper option (non-thesis). Upon completion of the first quarter, MS students are eligible to switch to a thesis option. 

During the first quarter, MS. students participate in a weekly laboratory rotation which consists of spending attending a group meeting, a shadow experience, and a one-on-one meeting with the faculty member/delegate. To accommodate a large number of faculty members, there may be weeks students may rotate in more than one laboratory. These short laboratory rotations allow for students to 1) gain a more holistic perspective of the department and 2) understand the dynamics/research within each laboratory. Based on these rotations, students can then switch to a thesis option and identify an appropriate thesis advisor. In some cases, the winter quarter is spent conducting a 10-week rotation in the proposed thesis advisor lab.

Minor in Toxicology

Graduate students whose major field of study is in a subject other than Toxicology are welcome to take courses and to earn a minor in Toxicology. The minor in Toxicology is designed to provide a foundation of knowledge in the field and the official designation of a Toxicology Minor provides documentation of your efforts and achievement. One faculty member of the Toxicology program must be on the student’s Advisory Committee to represent the minor.

Course requirements for a graduate minor

An MS minor has a minimum requirement of 16 credits.

TOX 511 Fundamentals of Toxicology (3)
