Toxicology, MS

Location(s): West Lafayette


About the Program


Toxicologists investigate the effects that chemical, physical or biological agents have on individuals, animals and the environment to determine if they are harmful. Toxicology is multidisciplinary, applying knowledge and techniques from biochemistry, chemistry, physiology, molecular biology, genomics, proteomics, and other disciplines.

Graduate students in toxicology typically come from a variety of chemical and life sciences backgrounds. The graduate program is designed to prepare students for positions in academia, government and military, consulting, and industry (for-profit and nonprofit). Many of these roles include basic, applied, and clinical research, spanning topics on mechanisms of toxicity, applications to safety evaluation of both new and existing chemicals, risk analysis to characterize and predict chemicals’ potential to produce acute and chronic illness in human populations, and more. Students will be able to select courses in accordance with their research needs and career goals.

Master’s students can pursue a thesis or non-thesis option. See below for each set of requirements.

Program Requirements - Thesis


30 Credits Required

Required Courses (20 credits)


Seminar Course (1 credit)


All students are required to take HSCI 69600 for 1 credit once and for 0 credit all remaining fall and spring semesters.

Selectives (2-4 credits)


Choose courses from the list below. Choices should be based on discussion with student’s major professor and advisory committee.

Thesis Research (6-8 credits)


Program Requirements - Non-Thesis


36 Credits Required

Required Courses (19 credits)


Professional Course (1 credit)


Seminar Course (1 credit)


All students are required to take HSCI 69600 for 1 credit once and for 0 credit all remaining fall and spring semesters.

Selectives (17 credits)


Choose courses from the list below. Choices should be based on discussion with student’s major professor and advisory committee.

Additional Requirements


Given that this program does not officially involve thesis research, students are strongly encouraged to obtain an internship relevant to their career goals over the summer, between years 1 and 2.

Writing requirement: A critical written evaluation of a topic related to toxicology is required to receive the non-thesis MS. The toxicant report in HSCI562 meets this requirement.

Additional Information


A full-time student has a minimum of 8 credit hours each semester (6 in the summer); however, it is recommended to enroll in at least 12 credit hours per semester. In addition to the core course listed in the student’s plan of study, the student’s course load can be supplemented by electives and/or additional research credits.

GPA Requirements


Graduate courses taken while registered as a graduate student at Purdue University may be considered for fulfilling the plan of study requirements only if the student has received grades of C or better. For courses at the 300/400-level taken as a graduate student or courses that represent either undergraduate or graduate excess credit or transfer credit, grades of B or better are required for fulfilling plan of study requirements.

A minimum of 24 coursework credit hours with no more than 6 credit hours at the 300/400-level is required for the thesis MS degree. A minimum of 36 coursework credit hous with no more than 6 credit hours at the 300/400-level is required for the non-thesis MS degree. The student’s advisory committee may approve alternative coursework in a plan of study that will assist the student in their research, including independent study projects under the guidance of a faculty member.

Graduate Programs Disclaimer


  • The student is ultimately responsible for knowing and completing all degree requirements. Students should consult with their advisor/department for more information.
  • Not all graduate programs may be actively recruiting students and course modality availability may vary. 
  • Please refer to the Explore Graduate Programs website for a list of currently available graduate programs.
  • Transfer credit policy: Credits earned for graduate study at other universities (both domestic and international) may be applied toward an advanced degree. Only credit hours associated with graduate courses for which grades of B- or better were obtained will be eligible for transfer. Any additional conditions under which credit transfers may be made are determined by the various departments.
