Graduate Degrees Offered


The doctoral degree is offered through the Federation of North Texas Area Universities.

Students in the Department of Biology can obtain a graduate degree with an emphasis in molecular biology, microbiology, neurobiology, general biology, botany, bioinformatics, virology or science education. The primary objectives of the department are to provide education and training  to prepare  students to enter a career in research, industry or teaching. Within the department there are opportunities for both teaching and research assistantships. For teaching assistantships, students should request an application from the department.

Admission Requirements

Please see the admissions section in this catalog. In addition to these general requirements, the Department of Biology requires the following for admission to its graduate degree programs:

  1. A bachelor’s degree in Biology or its equivalent. In addition admission to the Ph.D. program requires undergraduate courses in organic chemistry/biochemistry (2 semesters); calculus (1 semester); and physics (2 semesters). Students without an undergraduate Biology major will be considered if the departmental admissions committee believes that the student shows academic promise. These students may be granted provisional admission while they complete the requisite background coursework.
  2. Submission of GRE scores. Those accepted into a master's program typically exceed 148 verbal and 140 quantitative on the Revised GRE. Those accepted into the Ph.D. program commonly have GRE scores above 153 verbal and 144 quantitative on the Revised GRE.
  3. A statement of purpose (1-3 pages) that includes reasons for pursuing graduate work, background experience and professional goals. Please include all contact information and submit the statement of purpose directly to the Biology Graduate Advisor.
  4. Three letters of recommendation from persons familiar with the applicant’s academic capabilities. The referees should submit their letters of recommendations on letterhead stationary directly to the Biology Graduate Advisor by email.

International students should follow the application procedures outlined by the International Education Office.  In addition, applicants should also send the statement of purpose and letters of recommendation directly to the Biology Graduate Advisor. Those students wishing to apply for teaching assistantships must demonstrate English speaking proficiency by one of the following:

  • score of 26 or higher on the TOEFL iBT speaking section
  • score of 50 or higher on the Test of Spoken English
  • score of 7.5 or higher on the IELTS Speaking test
  • score of 4 or higher on the MELAB Speaking test

Applicants who satisfy the Graduate School’s admission standards are forwarded for review to the departmental admissions committee. This committee is responsible for recommending acceptance into Biology graduate programs.
