Biosciences, PhD


Banner Code:  SC-PHD-BIOS

College: College of Science  
Department: School of Systems Biology  

This program is a research-oriented field of study that prepares students for significant contributions in academic or industrial settings. It is broken down into two concentrations, Cell and Molecular Biology and Microbiology and Infectious Disease.

The academic component is a three-tiered structure. The first tier provides a set of core courses designed to advance research skills across all disciplines. The second tier comprises additional core courses and elective courses. The first two tiers are designed to be completed in approximately two years, including the comprehensive qualifying exam. Only on completion of these requirements, the qualifying exam, and a successful dissertation proposal can the students advance to candidacy status. The third tier focuses on research and culminates in a dissertation.

Admission Requirements

In addition to materials required of all applicants for graduate study as specified in the Graduate Admission Policies  section of this catalog, the following is also required:

  • Minimum 3.25 GPA in previous coursework with significant training in the biological sciences.
  • Three letters of recommendation from faculty members or individuals who have firsthand knowledge of the applicant’s academic or professional capabilities.
  • Statement of purpose consistent with the research interests of at least one faculty member in the program.
  • Scores on GRE general exam (required) and biology or biochemistry subject exam (recommended) taken within the past five years prior to date of application submission. The GRE exam is waived if applicants hold a master’s Degree from a fully-accredited U.S. university at the time of their application.
  • A TOEFL score of 575 on the paper-based exam or 230 on the computer-based exam is required of international students.

An interview may also be required. Applications should be submitted by January 1st for fall admission. Under unusual circumstances, applications may be considered for spring admission if they are received by October 1st. Applications will be considered until positions are filled. Students are encouraged to meet application deadlines to be considered for scholarships and stipends.

Strong candidates who lack several prerequisites may be admitted to provisional status. Removal from provisional status and continuation in the program is contingent on earning a GPA of 3.25 in the program’s fundamental courses, plus completion of missing prerequisites.

Students who have not taken a course in basic biochemistry will be required to complete one prior to BIOS 701 .

Reduction and Transfer of Credit

Reduction of Credit

For students entering the doctoral program with a master’s degree in a related field from a regionally accredited institution, the number of required credits may be reduced up to 30 credits, subject to approval of the program faculty and the college’s associate dean for student affairs.

Transfer of Credit

Graduate credits taken previously and not used toward another degree may be transferred, subject to the approval of the advisor, the program director, and the associate dean.

See the Graduate Policies  section for more information.

Degree Requirements


Students must satisfy all requirements for doctoral degrees expressed in the Academic Policies  section of this catalog.

Students in the doctoral program are required to present two research papers at a meeting or conference any time before graduation.

Doctoral Coursework (48-60 credits)


Bioscience Core (12 credits)


Concentration (12 credits):


▲ Concentration in Cell and Molecular Biology (CMB)

This concentration prepares students for significant contributions in an academic or industrial research career. Coursework covers microarray analysis of gene expression, proteome analysis, sequencing and analysis of gene polymorphisms, gene and genome evolution, molecular studies of disease mechanisms, mechanisms of toxicology and mutagenesis, developmental neuroscience, and biotechnological applications.

Students choose 12 credits from the following courses:

Concentration Total: 12 credits

▲ Concentration in Microbiology and Infectious Disease (MID)

Students in this concentration will be prepared for employment in academia, government, or industry. By stressing mechanisms of pathogenicity, physiology, metabolism, and genomic and proteomic analysis of pathogens, students will have a firm foundation for future research in infectious disease. Students will also be introduced to advanced laboratory practices, such as animal research methodologies and biocontainment laboratory work.

Students choose 12 credits from the following courses:

Concentration Total: 12 credits

Dissertation Committee


Upon admission to the program, each student is assigned an advisor from the bioscience faculty. The advisor may be changed by mutual consent of student and advisor, or petition to the program director and associate dean. With their advisor, students adopt an individual program that focuses on a specific area of research.

By the end of the fourth semester of coursework, students assemble a dissertation committee of four graduate faculty members with representation from at least two academic departments. The faculty advisor and the program director approve the program of study.

Qualifying Examination


On nearing completion of course requirements, students take a qualifying exam with a written and an oral component. At the discretion of the committee, the written qualifying exam may be retaken once if the student’s performance was deemed below satisfaction.

Advancement to Candidacy


Upon successful completion of the qualifying exam, the majority of all coursework, and an accepted dissertation proposal, students will be recommended for advancement to candidacy by the committee and the program director.

The semester after advancement to candidacy, students are eligible to enroll in dissertation research (BIOS 999 ). Students must review their progress on the dissertation with their graduate committee on a regular basis until graduation.

Dissertation Research (12–24 credits)


Note: No more than 24 combined credits from BIOS 998  and BIOS 999  may be applied toward satisfying doctoral degree requirements. Students register for a minimum of 3 credits of BIOS 999  in the first semester of advancement.

Doctoral Dissertation


After advancing to doctoral candidacy, students work with their dissertation committee to develop their dissertation proposal into a completed doctoral dissertation. The dissertation research should represent a significant contribution that is publishable in a refereed scientific journal. When the dissertation is complete, students will present their results to their graduate committee and defend their dissertation in a public forum.

Degree Total: 72 credits
