Biology (PhD)
Combines rigorous coursework, seminars and independent research across two broad areas: Molecular, Cellular & Developmental Biology and Ecology, Evolution & Behavior. Students benefit from faculty mentorship, teaching and research assistantships, and collaborative opportunities with partners like the Sullivan University College of Pharmacy and Health Sciences, while preparing for impactful careers in academia, industry or government.
Doctor of Philosophy in Biology
Unit: College of Arts and Sciences (GA)
Department: Biology
Academic Plan Code(s): BIOLPHDEEB, BIOLPHDMCD
Program Information
A broad range of courses are taught in most biological disciplines, although the department is focused in two major directions. Faculty in the Divisions of Molecular, Cellular, and Developmental Biology (MCD) and Evolution, Ecology and Behavioral Biology (EEB) have research interests in environmental microbiology, population and microbial genetics, developmental biology, plant and animal physiology, metabolism, plant and animal ecology, behavioral ecology, invertebrate zoology, and community and ecosystem ecology.
Students seeking the PhD Degree in Biology traditionally have a master's degree or its equivalent; however, students may enter the program with only the baccalaureate degree. Generally, the first year or two is spent in coursework, research is begun by the second year, and the thesis/dissertation completed in the final year.
Graduate Assistantships and Other Financial Support
Graduate Teaching Assistantships (GTA) are awarded by the Graduate Committee of the Department of Biology to meet the instructional needs of the Department and enhance and broaden the educational experience of doctoral students. All newly admitted students are automatically considered for this type of annual support, which includes a monthly stipend, tuition remission, and health insurance.
Financial support may also be available from individual faculty members who have research funding that supports graduate students as Graduate Research Assistants (GRA). The faculty members holding this support select students to fill these positions.
A small number of the most highly qualified accepted applicants will be nominated by the Department for University Fellowship awards, which carry a monthly stipend, tuition remission, and health insurance benefits. These students must meet qualifications set by the Graduate School.
Admission Requirements
Program admission requirements and application requirements can be viewed on the Department of Biology website. All applications are completed through the Graduate School at https://graduate.louisville.edu. There is no separate Department of Biology application.
The following requirements must be met in order to be admitted to the PhD program in the Department of Biology:
- The applicant must have a baccalaureate degree with a major in biology or an acceptable sub-discipline of biology.
- The applicant must meet the following admissions standards:
- Undergraduate GPA of 3.0 or higher
- Submission of GRE scores is optional; you may also submit MCAT or DAT scores. We suggest only submitting scores if they will help provide a more holistic perspective to your application. GRE scores are not used for funding decisions.
- For foreign students, a TOEFL score of 79 on the internet-based exam; at least 6.5 on the IELTS exam or Duolingo score of 105 (students holding a baccalaureate or advanced degree from an accredited institution in the United States are exempt from this requirement.
- All applicants must review the research specialties of the departmental faculty to ensure that an area compatible with the student's interest is available. Applicants for the PhD program must communicate with a member of the biology faculty prior to admission and receive agreement that the faculty member will serve as the major professor. No formal admission to the program can occur without the preliminary acceptance of a mentor. You may visit our department website to review faculty contact information.
Your application will be complete when we have all of the following (final action on an application cannot be taken until all items have been received):
Official documentation must be sent to the Graduate School. Send the following:

- Official TOEFL, IELTS or Duolingo scores (international students).
Deadline for completed applications:
-
December 1 for Fall admission
-
July 1 for Spring admission
