The Department of Biochemistry and Biophysics is an administrative division of the School of Medicine and a member of The Graduate School. The graduate program offers instruction and research opportunities leading to the Ph.D. degree. Although the department offers the M.S. degree, the graduate program is not designed as a terminal master's curriculum. Applicants are offered admission with the expectation that they will complete their doctorate.
Modern research in biochemistry and biophysics is designed to address mechanism and function; it utilizes the paradigms of molecular biology, but is influenced by chemistry, physics, and genetics. The philosophy of the department and its graduate program is to provide students with broad training in modern approaches to the field and unique opportunities for multidisciplinary training.
Students are admitted to the graduate program through the BBSP portal, complete a minimum of three laboratory rotations, and then join the Department of Biochemistry and Biophysics at the end of their first year. All students in the department are required to complete a seminar in biochemistry (BIOC 701) OR seminar in biophysics (BIOC 704); BIOC 712, which is a grant writing course designed to help prepare students for their comprehensive written examination; and BIOC 715, which is a scientific presentation course. Students are also required to complete nine credit hours in core courses and four credit hours of electives. Further information on course requirements may be found at www.med.unc.edu/biochem/students/degree-requirements. Students in the combined M.D./Ph.D. program are required to complete all course requirements.
The director of graduate studies advises entering students about course selection until the student chooses a research sponsor. Students select research sponsors from the department's primary and joint faculty members following the three laboratory rotations. After a research sponsor has been selected, a dissertation committee is formed to review the student's yearly progress. The examinations required for admission to candidacy for the Ph.D. are administered as a comprehensive oral exam, a comprehensive written exam, and a final oral defense of a dissertation. The comprehensive oral exam (defense of the initial thesis proposal) will stress the dissertation proposal and related areas in an effort to ascertain the student's understanding of the research project that he/she is undertaking. The comprehensive written examination will cover major topics in the areas of biochemistry and biophysics and cell and molecular biology. The most important requirement for the Ph.D. degree is a final oral defense of a dissertation or original research carried out independently by the candidate.
Financial Aid and Admissions
Funds available from the University, the department, and individual research grants provide stipends for students. All applicants are considered for special fellowships and teaching or research assistantships. In recent years students received a stipend of $27,500 plus in-state tuition and fees. Major medical insurance was also provided. Nonresidents with predoctoral fellowships or assistantships are recommended for special tuition rates. Applications are considered from prospective graduate students who present evidence of superior scholarship in biology, chemistry, or biochemistry. The department recommends that students prepare themselves by taking general and organic chemistry, biochemistry, biology, physics, and calculus. It is anticipated that students who have not had these courses will take them, as appropriate, after their arrival. Departmental information may be obtained through the department's Web site: www.med.unc.edu/biochem. Applicants should apply online at gradschool.unc.edu/admissions.
The faculty research interests are diverse and include research in the following areas: cell signaling and growth control, DNA repair and replication, membrane biophysics and function, molecular regulation including transcriptional control, nervous system development and function, and protein structure/function, including enzymology. Model systems used by the faculty range from bacteria to mammals; techniques span molecular biology to physical biochemistry. A brochure describing the department and more detailed faculty research interests can be obtained by writing to the director of graduate studies of the Department of Biochemistry and Biophysics, or by visiting the department's Web site: www.med.unc.edu/biochem.
The departmental research facilities are centered in the Genetic Medicine Building, which is within walking distance of other medical school departments, research centers, and the departments of biology, chemistry, and physics. The building is equipped with instruments for molecular biological, biochemical, structural, and biophysical research. Animal care facilities are available to support the department's research endeavors. Research and training support is provided by several core facilities on campus. Educational support is provided by the BBSP.
