Ph. D. in Quantitative Biology Admission Requirements
The Department of Biology offers a Doctor of Philosophy degree in quantitative biology with research emphasis in Genome Biology & Genetics, Ecology & Systematics, or Microbiology. The doctoral program is designed to train students to apply sophisticated quantitative techniques to solving basic and applied problems in biology. Students in this program will attain substantially greater quantitative skills than in traditional doctoral programs in the biological sciences, providing them with a competitive advantage in business, industry, government, and academia.

How to apply

First, read the general instructions for applying to the graduate program and download the checklists available on the Office of Graduate Studies webpage. Then read the Biology Departments How To Apply page for additional biology specific instructions.

Admission requirements

Students interested in pursuing a Ph.D. in the Department of Biology must apply to either the "B.S. to Ph.D. track" or the "Ph.D. program", with the corresponding prerequisites:
B.S. to Ph.D. track: A bachelor's degree in biology, or a bachelor's degree in some other discipline with at least 12 hours of advanced level coursework (junior or senior level courses) in biology.
Ph.D. program: A master's degree in biology, or at least 30 hours of graduate level coursework in biology is required.
A minimum undergraduate GPA of 3.0 (4.0 scale), as calculated by the Graduate School, is expected. An applicant's GPA in science courses will be taken into consideration. If an applicant has a master's degree, the GPA from their master's degree will also be considered. For applicants with up to 30 hours of graduate coursework but no master's degree, the GPA from those hours will be also be taken into consideration.
GRE: A satisfactory score on the Verbal and Quantitative sections of the Graduate Record Exam (GRE). Successful students tend to have a minimum combined score of 301 on the Verbal and Quantitative sections under the new scoring system (1100 old scoring system), with strong performance on the Quantitative section of the GRE.  

Letters of Recommendation: Favorable letters of recommendation from at least three individuals able to assess the applicant's potential for success in a doctoral program in quantitative biology. Evidence of previous research experience may also be considered.

International students: Students whose native language is not English must provide a score on the Test of Spoken English (TSE) of at least 45, a minimum score of 23 on the Speaking portion of the TOEFL iBT exam or a minimum score of 7 on the Speaking portion of the IELTS exam. See the following website for complete details:

Other requirements: In addition to the standard application materials, we suggest that you contact faculty that you are interested in to see if they are currently recruiting students. During your first semester you will join/rotate through one or two labs that you are interested in and that are currently recruiting students. If no fit is found during your first semester, you have the option of rotating through additional labs the second semester. Please visit the faculty pages on the UT Arlington Biology site ( to find faculty research that you might be interested in. In addition to the faculty listed on our website, we are hiring new faculty this year with research interests across all of our major disciplines: genomics and genetics, microbiology and molecular biology, and global change/ecology and evolution. As soon as these new hires become official, the new faculty will be added to our website. We feel confident that you will find an exciting and dynamic dissertation lab to join. To apply to the program, see the Biology How to Apply ( and the UT Arlington how to apply ( Please not that the biology department deadline is much earlier and is the deadline you should use.

All applications are reviewed on the following schedule:

for entrance in the Fall semester.

Completed applications will be under review starting January 10 (e.g., January 10, 2021 for Fall 2021 entry). Applicants are notified of admissions decision typically in the January through March time frame.

for entrance in the Spring semester.

Completed applications will be under review starting September 15 (e.g., September 15, 2021 for Spring 2022 entry). Applicants are notified of admissions decision typically in the September through November time frame.

Application status

Students who have applied to the Biology Graduate Program can check their application status by contacting Biology graduate program assistant Gloria Burlingham by email at or by phone at 817-272-2871. Please include your name and application number.

Funding opportunities

Ph.D. students are not admitted to the Biology graduate program without financial support in the form of Graduate Teaching Assistantships (GTAs), funded by the department, or Graduate Research Assistantships (GRAs), funded by grants to individual faculty members. Assistantships are awarded on a competitive basis. In general, there are more assistantships available for the fall semester than the spring semester. Please see the How to Apply for target application dates.
All Ph.D. students enrolled full-time and receiving an assistantship are eligible for in-state tuition regardless of residence. The Graduate Dean awards small fellowships to outstanding new students.

Areas of research

Ecology and Evolution; Genome Biology; Microbiology and Molecular Biology.

Career opportunities

Students who completSe the Ph.D. program often go into academia, biotechnology, biomedical industries, government research, or positions in research institutes.
