Curriculum For The PhD
The Toxicology graduate curriculum consists of several components: (1) core course requirements, (2) seminar requirements, (3) elective course requirements, and (4) experimental research. It is our belief that research is the most important part of this doctoral training program. As such, the PhD degree is awarded only after a student has conducted an independent, hypothesis driven research project and then written a dissertation that demonstrates a high level of intellectual competence.
A total of 96 credit hours is required to complete the PhD program, and The Graduate School requires an academic load of 16 credit hours per semester. A minimum of 30 graduate credit hours must be accumulated before taking the qualifying examination, with 24 credit hours being course work credit. These will come from core courses, electives, seminars, and research (TOX 595, PhD Research in Toxicology). Given that toxicology is highly interdisciplinary, our curriculum reflects that a thorough grounding in basic sciences is indispensable. To ensure that our trainees obtain broad and in-depth knowledge necessary for success, in addition to the Core Curriculum, 6 credit hours as electives are required, and at least 3 of these credits must be from toxicology (TOX) electives.

# Includes a required ‘boot camp’ prior to the start of the course that serves as a refresher for students who may have already had some statistics/biostatistics, as well as providing fundamental information for students who are new to biostatistics. Students also receive hands-on training in the software that is used during the course.
Exemptions from the Core Curriculum
A student interested in an exemption from any core course listed above should discuss this with the Program Director, who will help determine whether an exemption may be appropriate. Students should come to this meeting with the details about the content of prior graduate-level courses (description, syllabus) and the grade earned. After a review of this material, the Program Director may advise the student to take the required course, or the Program Director will give the green light for the student to request a formal exemption. To do this, the student must submit the request along with a comprehensive course description (i.e., including lecture syllabus) of a prior course, grade earned, and a little bit of other information. The request then needs to be reviewed and approved by the course instructor and the Senior Associate Dean of Graduate Education and Postdoctoral Affairs. The instructions and the form for making this request can be found on the GEPA website on the forms page.
Seminar in Toxicology (TOX 558)
This seminar is designed to give graduate students experience presenting scientific matter to an audience of peers and experts, refine public speaking skills, and to assist in the development of the student’s ability to identify critical problems and ask critical questions regarding a particular research area. Therefore, in addition to giving an oral presentation, all students are expected to be active participants in the course by asking questions and by providing written feedback to peers. The seminar must be taken 4 times before the thesis defense. It is offered every spring semester. Students in years 1-4 are required to register for and attend all of the seminars. Students in year 5+ are strongly encouraged to continue to attend the seminars.
First year students will give an oral presentation. Topic selection will be based on discussion with the Course Director, but will generally be derived from topics pertinent to toxicology and environmental health—often closely associated with one of the laboratories in which the student rotated. Second, third and fourth year students will present a seminar based on their ongoing research. The order of student presentations will be distributed at or just prior to the start of the term, and will generally proceed alphabetically, by year, with the fourth year students going at the start of the term (and first year students presenting at the end of the term). A grade of C or below will necessitate repeating of the course by the student (e.g., required registration and giving an oral presentation during the 5th year). Poor attendance can result in a failing grade.
Elective Courses
Prior to the PhD thesis defense, a minimum of 6 credit hours must be earned from elective courses, and at least 3 of these credits must be from toxicology (TOX) electives. The selection of a strong supplementary course program should be conducted in consultation with the student’s faculty advisor and thesis advisory committee. Some recommendations are provided below. However, this list is by no means exhaustive, and the frequency of these courses is approximate. Students are encouraged to check the scope and availability of courses in any given year via the University course website since offerings change regularly and new courses are added.
