The Master of Science (M.S.) curriculum provides motivated individuals the opportunity to develop in-depth understanding of microbiological processes and to emerge from the program with the skills for making valuable contributions to research, education and biotechnology endeavors. Students are educated in research systems and in communicating science to colleagues and the public.

M.S. Course Requirements

There are courses taught by MGP faculty, as well as electives offered in numerous disciplines across campus (e.g., Biochemistry, Bioinformatics, Biotechnology, Animal Science, Food Science, Genetics, etc.). Elective courses are chosen by the student, with the help of the student's advisory committee. Continuous enrollment requirements of the Graduate School (for tuition and health benefits) requires all graduate students enroll for a minimum of nine credits in each Fall and Spring semester. After the first year, most of these are Research credits. In a two-year M.S. program, students need to complete 30 credits total, of which 18 credits must be graded.  Details of the graduate student support plan (GSSP) are available from the graduate school homepage. All graduate students must maintain a minimum cumulative grade point average of 3.0.  The program is completed upon submission of a thesis and completion of all credit requirements.

The MGP requires the following MB course credits in the M.S. degree program. All 500 & 700 level courses are letter graded, whereas 600 & 800 level courses use satisfactory/unsatisfactory grading policies.

Microbiology Courses (3 credits each)

The field of Microbiology includes several specialized disciplines such as bacterial physiology, microbial genomics and metagenomics, microbiomes, environmental microbiology, immunology, host-pathogen interactions, molecular genetics and virology.  At NC State, M.S. students can take courses that represent, and focus on, the various disciplines of Microbiology. Prior experience can impact which courses in which the student enrolls. Prerequisites in biochemistry are often required of these courses.  For the M.S., at least 6 MB graded graduate credits must be taken, but students typically take more toward the 18 total graded credits required. Example courses, fitting into two microbiology “tracks” or focus areas are:

Environmental / Industrial

Graduate Elective Courses (MB 500 – 800 or others)
Students can select elective courses offered by several departments at NCSU. Letter graded or satisfactory/unsatisfactory course formats can be used. M.S. students are allowed a maximum of 6 credits in MB 695 Microbiology Research; the remaining credits will be obtained from other MB or elective courses. Selection of elective courses is done by the student, in consultation with and approval by the advisory committee. Below are examples of elective courses available.

Additional Course Requirements

As listed above, students are required to register for the following:

  • MB 686 Teaching Experience
    Students receive academic credit for participating as a teaching assistant in an approved course. 1-2 credits.
  • MB 695 Microbiology Research
    MB 695 provides credit for research performed in the M.S. program.  Students may sign-up for a variable number of MB 695 credits each semester, with a maximum of six credits allowed toward the M.S. degree.
  • MB 601 Seminar in Microbiology
    The MGP requires all graduate students to attend Microbiology seminars throughout their degree program. M.S. students must register for at least two credits (two semesters) of Seminar.

MB 590 Other Professional Development
The MGP requires all graduate students to attend either the Microbiology course in Professional Development and Responsible Conduct of Research, or a similar module offered in related programs (BIT, GN, etc.). One credit hour required.

Advisory Committees
Upon admission to the graduate program, the Director of Graduate Programs (DGP) serves as a temporary advisor. Prior to completion of the first year of study, each student is required to select a thesis advisor (major professor) and a graduate advisory committee that will meet no less than once a year. The M.S. advisory committee will consist of the student's thesis advisor and at least two additional faculty members from the MGP faculty. All required committee members must hold appointments within the NCSU Graduate School. Scientists who are not members of the Graduate School faculty (e.g., adjunct faculty, industry scientists) may be appointed to the committee, but will be in addition to the required members.

Teaching Experience
The MGP has established a minimum teaching responsibility as partial fulfillment of the requirements for the M.S. degree. Graduate students must serve as a laboratory teaching assistant for one semester in an on-campus NCSU course. Example courses fulfilling the teaching requirement are: MB 352, MB 412, MB 452 and BIO 181. Specific tools for enhancing teaching effectiveness are provided for teaching assistants, including workshops and constructive evaluation by the instructor and the students. The teaching requirement should be fulfilled at the earliest possible time in the graduate program. One credit of MB 686 is provided for each semester the student teaches.

Graduate Plan of Work (PoW)
The student and major professor will outline the plan of graduate study as soon as possible, preferably by the end of the first semester. The plan will be submitted for approval or amendment by the student's advisory committee, and will be formally submitted to the graduate school no later than the end of the student's first year at NCSU. A Plan of Work will include all courses, a tentative thesis title, and an anticipated timetable for taking each course.

Annual Research Progress Reports
The MGP will facilitate scheduling an annual meeting of the student's advisory committee, at which the student will make an oral presentation and submit a written report on their laboratory research. A Graduate Student Progress Evaluation Form will be completed by the advisory committee. A satisfactory evaluation will be necessary for the student to receive Departmental support and/or be able to register for the next semester.

Transferring Between Degree Programs
Students who matriculate in the M.S. program may at a later date wish to bypass the M.S. degree and transfer directly into the Ph.D. program. The student's advisory committee must be supplied with sufficient evidence of research ability, such as published manuscripts, published abstracts, or other scientific presentations, to justify the transfer. The student must meet with the advisory committee to present current research results and research objectives for the Ph.D. dissertation. Following the meeting, a letter signed by the advisor is forwarded to the Director of Graduate Programs (DGP) recommending transfer into the Ph.D. program. Upon approval the student follows the requirements of the Ph.D. program, including the Preliminary Examination.

Students may also wish to pursue admission to the Ph.D. program following completion of the requirements for the M.S. degree in Microbiology at NCSU. Similarly, a student may consider transferring from the Ph.D. program into the M.S. program after a year or more in the graduate program. In either instance, a meeting of the student's advisory committee is held that specifically addresses the status of the student's program. A letter signed by thesis advisor is then submitted to the DGP with a specific recommendation. Notification of admission or change in program will then be made by letter to the student and their advisor.

Any other transfers between degree programs must receive approval by the student's advisory committee and a specific recommendation submitted to the DGP.

Thesis and Defense
Prior to completing the degree program, M.S. students must write a thesis on their research. They must conform to the regulations laid down in the NCSU "Thesis and Dissertation Guide". The content and structure of the thesis will be approved by the advisory committee, and all degree candidates are expected to prepare their research results for publication prior to completing their program. In addition to preparing a thesis, M.S. candidates are encouraged (but not required) to present a seminar on their research around the time they defend their thesis with the advisory committee. M.S. students may register for MB 690 Master's Exam in the semester they expect to defend. Subject to the satisfactory defense of the M.S. thesis, the advisory committee will approve it for transmittal to the Graduate School.
