Program of Study
The Department of Cell Biology and Physiology of the School of Medicine offers a program of study leading to the doctor of philosophy degree in Cell and Developmental Biology. The primary purpose of the graduate program is to train students to become biomedical scientists. The program provides training for students whose research/teaching career objectives are faculty positions in medical school basic sciences departments. However, the flexibility of the program also provides for the training of students who seek careers in basic science as well as clinical science departments of medical schools, in other professional schools such as dental schools, in liberal arts academic departments such as biology, or in state, federal, private, and industrial research laboratories. The program for the Ph.D. normally takes five to six years to complete. Persons interested in a combined M.D./Ph.D. program must be accepted into the School of Medicine and the departmental graduate program, whereupon the combined studies are scheduled in accordance with individual requirements.
Some of the department's areas of specialization are cell biology, developmental biology, neurobiology, reproductive biology, membrane biology, molecular biology, cell signaling, and parasitology. Ph.D. students take graduate level courses in their first year as well as conduct laboratory rotations. Students who join the departmental graduate program at the end of year one are examined for advancement to candidacy. Ph.D. candidacy is followed by a dissertation based on original research is conducted under the supervision of a faculty advisor. Additional information is available on the departmental Web site (www.cellbio.med.unc.edu/grad/depttest/welcome.htm).
Admission to the departmental graduate program is via the unified Biological and Biomedical Sciences Program (BBSP) at UNC. A B.A. or B.S. degree is required for admission. Applicants are expected to have a strong background in the biological sciences, chemistry, physics, and mathematics. Details of the application process are available at the BBSP website (www.med.unc.edu/bbsp) and The Graduate School website (gradschool.unc.edu/admissions). Briefly, the application should include transcripts, Graduate Record Examination (GRE) scores, three letters of recommendation, and a personal statement outlining career goals.
The department occupies 40,000 square feet of research and office space (in addition to teaching space), primarily in Taylor Hall and the Biomolecular Research Building in the School of Medicine. The department and its research laboratories are a biotechnological resource available for qualified scientists in the University, state, and region. The laboratories house instrumentation for transmission, scanning, and cryo electron microscopy, as well as equipment to prepare biological specimens for these techniques. The Electron Microscope Facility contains a multipurpose JOEL 820 scanning electron microscope and a high-resolution FEI-Philips Tecnai 12 transmission electron microscope. Ancillary facilities include fully equipped darkrooms and equipment for ultramicrotomy, critical point drying, rotary evaporation, sputter coating, and a state-of-the-art, high-resolution Reichert freeze fracture system. A world class facility is available for optical imaging of all kinds, including digitized video microscopy, confocal microscopy, and fluorescence lifetime imaging microscopy, two-photon confocal microscopy, nanovid microscopy, and fluorescence recovery after photobleaching.
Assistantships and Other Student Aid
Students are supported by a stipend of $27,500 annually plus tuition, fees, and medical insurance.
