Introduction to Program and Program Rationale
The primary objective of the Biophysics Program at Harvard University is to prepare investigators with diverse backgrounds for independent research careers in which the concepts and methods of physical science are applied to biological problems. The program is administered by the Committee on Higher Degrees in Biophysics, which is comprised of senior representatives from the Departments of Biological Chemistry and Molecular Pharmacology; Molecular and Cellular Biology; Chemistry and Chemical Biology; Physics; Genetics and Pathology. Owing to the interdepartmental nature of the program, research may be pursued on the Cambridge campus (in the Departments of Molecular and Cellular Biology; Chemistry and Chemical Biology; Physics; the School of Engineering and Applied Sciences; etc.) or the Boston campus (including the Harvard Medical School, Division of Medical Sciences, and the 11 Harvard-affiliated teaching hospitals, which include the Dana-Farber Cancer Institute, Brigham and Women's Hospital, Children's Hospital, Massachusetts General Hospital, and the Beth Israel Deaconess Hospital).
The goal of the biophysics program is to nurture independent, creative scientists. To this end, the first part of the program seeks both to introduce the student to the faculty members and their research directly, enabling the student to make a considered choice of research advisor, and to involve the student in the diverse areas of biophysics through laboratory as well as coursework. This first two years provides a background for the second part of the program: the training of the student to be an independent scientist by a period of intensive research, culminating in publications and the PhD degree.
Admissions and Scholarships
Information on applications for admission and financial aid may be requested from the Admissions Office, Harvard Graduate School of Arts and Sciences, Richard A. and Susan F. Smith Campus Center, 3rd floor, 1350 Massachusetts Avenue, Cambridge, MA 02138. Online submission of the application is required. See www.gsas.harvard.edu.
Applicants should state clearly in this application their desire to enter the program for the PhD degree in biophysics. All prospective students are urged to file the application forms well in advance of the deadline in early December. Late applications will not be considered. Scores on the general Graduate Record Examination (GRE) are required except in special circumstances. GRE subject tests are recommended. Due to the early application deadline, applicants should plan to take GRE tests no later than October to ensure that original scores are received by the December deadline. TOEFL is required of all foreign applicants other than those whose native language is English.
Final decisions concerning admission are made by the dean of the Graduate School of Arts and Sciences and the candidates are notified by letter from the Admissions Office.
After being accepted for admission, applicants are encouraged to make arrangements with the administrator of the Committee on Higher Degrees in Biophysics, Building C2, Room 122, 240 Longwood Avenue, Boston, MA 02115, (617-495-3360) to visit the University.
Students with the MD Degree
Students who already have the MD degree will find an opportunity to improve their knowledge of basic science in either of two ways:
1. Opportunities may be available in the several departments to engage in investigations as a research fellow under the direction of a member of the faculty. No university credit toward a degree is given for such work. Questions concerning the appointment of research fellows should be directed to the faculty members.
2. Under special circumstances, students who have received the MD degree may become candidates for the PhD degree in biophysics, providing their qualifications for admission are approved and providing they are prepared to fulfill the normal requirements for the degree.
Combined MD-PhD Program
Students admitted to Harvard Medical School, as candidates for the MD degree, may also apply for admission to the biophysics program in order to earn a PhD degree in biophysics. This program may be of particular interest to prospective medical students with a strong background in physics and to students enrolled in the Harvard-MIT Division of Health Sciences and Technology. Applications to the biophysics program happen in the fall of the second year of an MD-PhD student's tenure.
Suggested Undergraduate Preparation
The large list of courses below would provide an ideal background for a student's coursework in specialized areas of biophysics.

Advice to International Students
Students from non-US countries who are continuing their studies at Harvard, or who are applying for admission to the University, should communicate with the Harvard International Office, 1350 Massachusetts Avenue, Room 851, Cambridge, MA 02138, which is especially designed to help and advise international students. The immigration and naturalization laws specify many complex legal requirements affecting the status of international students and scholars during their period of study in the United States. The office is prepared to furnish information to aliens on visa requirements, permissible employment, income tax liabilities, and many other official restrictions in effect under existing laws of the United States.
All students accepted into the program are awarded full support, including a stipend, full tuition, and health fees contingent on continued satisfactory progress. Teaching fellowships are available. Second-year students must teach one term as part of their academic requirements. Students are responsible for finding their own teaching position in any one of the participating science departments. Students in their third year and beyond and who are engaged in full-time research become the financial responsibility of their faculty mentors.
Students are encouraged to apply for external fellowships, such as those administered by the National Science Foundation, the National Defense Science and Engineering Fellowship, and the National Institutes of Health, or other foundations, such as the Hertz and Ford Foundations, which are available on a competitive basis to graduate students in biophysics. Applications for those fellowships should be made directly to the appropriate agencies.
Certain limited funds are available as beneficiary aid, distributed by the deans of GSAS to students in the form of gifts or loans to meet unexpected financial needs. Information on loans and beneficiary aids may be obtained from GSAS.
Program of Study
Most graduates of the biophysics program at Harvard have been undergraduate majors in physics or physical chemistry, though a few have come from biology. Consequently, the course requirements for admission are flexible. Each student's program of graduate study is planned in consultation with a faculty advisor. The degree program is designed to be completed in a maximum of six years.
The first year's training in the biophysics program provides an introduction to five diverse areas of biophysics: 1) structural molecular biology; 2) cell and membrane biophysics; 3) molecular genetics; 4) physical biochemistry; and 5) neurosciences. The curriculum includes learning experiences in a laboratory environment as well as coursework. The program is flexible and special effort has been devoted to minimizing formal requirements.
The laboratory experience is organized as a full course, Biophysics 300. In the first ten weeks of the fall term, faculty members associated with the biophysics program give seminars describing the current research interests of their own laboratories. Following this, a student spends six-week periods in each of three different laboratories. The list under Participating Faculty and Their Special Fields names some of our professors who currently support biophysics rotation students. In order to make sure that the student gains familiarity with several fields of biophysics, each of the three laboratory experiences usually is selected from a different one of the areas of biophysics listed above. It will also be possible to work on a suitable problem in mathematical biophysics in place of one of the three laboratory rotations.
Biophysics 170, Quantitative Genomics, an in-depth study of genomics: models of evolution and population genetics; comparative genomics: analysis and comparison; structural genomics: protein structure, evolution and interactions; functional genomics, gene expression, structure and dynamics of regulatory networks.
Biophysics 205, Computational and Functional Genomics, Experimental functional genomics, computational prediction of gene function, and properties and models of complex biological systems. The course will primarily involve critical reading and discussion rather than lectures.
Biophysics 242, Special Topics in Biophysics, a required course, invites two or more professors in the spring term to speak on new areas of their own research, thereby introducing students to new questions and methods of research that would not normally be accommodated by the regular curriculum. Past topics have included structure and function of DNA; oncogene products; two-dimensional nuclear magnetic resonance; RNA structure and function; diffusion; atomic interactions in protein-ligand interactions; analysis and design of novel protein-protein and protein-ligand interactions based on 3-D structural information; structure/ function relationships in peptide antibiotics; biological interactions at surfaces; enzyme-catalyzed redox reactions: catalysts and cofactors; molecular neurobiology and systems neurosciences; conceptual foundations and recent developments in computational biology, genomics, and macromolecular interactions; new biology through physics: molecular discoveries with light; information theory and neural systems; X-ray and electron crystallography and high-resolution light microscopy; computational and functional genomics; molecular motors; exploring advanced imaging techniques, and brain, behavior and biophysics.
In addition to these courses, each student normally takes one course in each of the five biophysics areas mentioned previously. Most coursework is completed within the first two years.
A student may also gain knowledge in a particular area by taking reading courses or by studying independently while registered for TIME.

Formal Academic Requirements
The academic requirement for the PhD degree consists of not less than two years—at least one of which must be in residence at the Harvard Graduate School of Arts and Sciences—devoted to advanced studies approved as suitable preparation for the degree by the Committee on Higher Degrees in Biophysics. In estimating the extent of a candidate's study for the degree, the advanced work done in other graduate departments of Harvard or of other universities will be considered. A year's work for a resident student normally consists of four courses (eight half-courses) of advanced grade. Under certain conditions summer courses taken at the Marine Biological Laboratory in Woods Hole may be counted for credit toward the degree.
The biophysics program anticipates completion of formal course studies in the first two years.
Languages. There is no language examination but students are encouraged to gain a reading knowledge of one foreign language, preferably selected from German, Russian, and French.
Dissertation Qualifying Examination. Before beginning dissertation research, it is normally necessary for the student to fulfill the following requirements: (1) pass one Harvard course within the subject areas listed above; (2) do satisfactory work in three laboratory rotations; and (3) submit and defend an original research proposal. The purpose of the oral defense of the qualifying research proposal is to ensure that the student is adequately prepared to embark on dissertation research. The exam is normally taken in the fourth term of residence, before the chair and three examiners knowledgeable in the field of the research proposal. Reexamination will be permitted. As a rule, students will not be permitted to enter the third year of graduate study unless the qualifying examination has been passed.
Dissertation. Selection of a dissertation advisor normally occurs in a student's second year of study. Independent research on one's dissertation technically begins once the qualifying examination is successfully completed.
The program policy is that all students who have successfully completed their qualifying exam promptly establish their Dissertation Advisory Committee (DAC). The DAC has several functions. The first will be to approve the student's dissertation proposal. Second, the DAC, in consultation with the dissertation advisor, will periodically evaluate the progress of the student's dissertation research. The DAC may make recommendations to the dissertation advisor as well as the student with regard to the student's progress towards completion of the dissertation. Third, the DAC, in consultation with the dissertation advisor, will determine at what point the student is ready to defend his or her dissertation.
It is expected that the preparation of a dissertation will usually require full-time research for not less than one-and-a-half years after the qualifying examination. The dissertation must give evidence of independent original research and be clearly, logically, and carefully written in good English. The final manuscript must conform to the requirements described in The Form of the PhD Dissertation.
On receipt of the dissertation, the chair of the Committee on Higher Degrees in Biophysics will appoint a reading committee of three to judge the dissertation. The dissertation defense is comprised of two parts: the public seminar and the private defense. In the private defense the candidate will be questioned on the subject of the dissertation and its relation to the student's special field and collateral subjects. If the reading committee is unable to agree on its recommendations, the question of the acceptance of the dissertation will be decided by the Committee on Higher Degrees in Biophysics.
Upon completion of all the requirements, the original bound dissertation, with the dissertation acceptance certificate signed by the reading committee, will be submitted to the Office of the Registrar of the Graduate School both electronically and in hard-copy, for inspection by any member of the Faculty of Arts and Sciences.
After Commencement, an original bound copy will be deposited in the Harvard Library, open to public inspection. A second bound copy will be kept by the committee chair, and a third bound copy will be kept by the department in which the student worked.
