Graduate Research Doctoral Degree Program


Direct Admission to Toxicology:

For students specifically interested in a Ph.D. in Toxicology and Cancer Biology, direct application and admission to the Toxicology and Cancer Biology doctoral program offers several opportunities. Students directly admitted to the program may select a dissertation mentor from among Core faculty and all Joint faculty of Toxicology and Cancer Biology. Together, these faculty offer students directly admitted to the program a full spectrum of research programs related to environmental, agricultural and biomedical toxicology and cancer biology.

Admission through the Integrated Biomedical Sciences (IBS):

For students who are not certain of their desire for a Ph.D. in Toxicology and Cancer Biology, admission through the IBS program offers the opportunity to consider research programs in one of six departments participating in IBS, including the Department of Toxicology and Cancer Biology. For further information about admission to IBS, please visit the IBS website.

Admission Requirements

Applicants must meet the following requirements for admission to the University of Kentucky Graduate School and the Toxicology and Cancer Biology program.

  1. An appropriate degree (e.g., Chemistry, Biological Sciences) from an accredited college or university.
  2. A minimum grade point average of 3.0 on a 4.0 scale.
  3. An average Graduate Record Examination (GRE) score on the verbal, quantitative and analytical sections that is great than 50th percentile.
  4. For international applicants, the minimum acceptable TOFEL score is 550 (paper-based), 213 (computer-based), or 79 (internet-based). The minimum IELTS score is 6.5.

Applicants with lesser qualifications will be accepted only if other indices of performance and qualification are outstanding.

Admission requirements for the MS shall be the same as established for PhD students applying to the GTC program.

Financial Assistance

All students accepted into the Doctoral program are supported in the first year by the department. The current minimum stipend is $25,000 per year plus the tuition fee to cover the curriculum-required or graduate advisory committee-recommended courses, student health insurance and activity fee. During this first year, students are required to carry out at least three two-month rotations in laboratories of departmental faculty, with the aim of identifying a mentor who will guide their Ph.D. research. The student's mentor is responsible for identifying financial support for the doctoral student from year two onward. Most financial assistance for students comes from the grants of individual faculty members, the NIEHS training grant and various University fellowships.

Students in the M.S program are not eligible for a research assistantship. Students are encouraged to apply for non-service fellowships and loans from the University, various agencies, foundations, etc.


The Department of Toxicology and Cancer Biology offers programs of study leading to the Master of Science and Doctor of Philosophy degrees. Requirements for those students working directly towards the doctoral degree and for Master degree are discussed in the links to the right.
