OVERVIEW OF PROGRAM
The central focus of the graduate program in Biochemistry and Molecular Biophysics (BMB) is the relationship between biological form and function at a fundamental level. This program provides students with an integrated and interdisciplinary approach to graduate education. The faculty in the BMB Graduate Group are unified by a common interest in understanding biological phenomena at the quantitative, mechanistic or molecular level, drawing on modern biochemical, biophysical, chemical and physical methods. The graduate program trains students in the scientific concepts and methods necessary for conducting basic research and its application to medicine. The program is designed to prepare students for careers as independent investigators.
The strength of the program resides in its unusually broad combination of faculty interests and disciplines. Faculty members are drawn from many departments within the Perelman School of Medicine, the Schools of Dental and Veterinary Medicine; the School of Arts and Science, from the School of Engineering, and from affiliated research institutes such as the Wistar Institute and the Fox Chase Cancer Research.
Faculty Research Interests
• Regulation of metabolism.
• Elucidation signaling mechanisms and pathways that result in physiological events, such as sensory transduction, cell division, death and control of the cell cycle.
• Determination of protein, RNA, DNA and virus structures.
• Protein and enzyme folding, function design and engineering.
• Regulation, transport and processing of RNA.
• Structure and function of membranes, including ion channels, gates, pumps and pores.
• Enzyme structure and function

• The molecular basis of immunology.
• Study of protein assemblies and the basis of specific protein-protein interactions.
• Molecular basis of energy transduction, including contractility, bioenergetics an photosynthesis.
• Development of novel high-resolution magnetic resonance and optical imaging methods.
Faculty in the Biochemistry and Molecular Biophysics Graduate Group typically use a combination of biochemical, biophysical, chemical and physical methods to unravel these complex biological events. These methods include:
• High resolution spectroscopies, including optical, infrared, fluorescence, phosphorescence, pump-probe spectroscopies
• X-ray diffraction
• Microscopy, including electron, optical and fluorescence microscopy
• Nuclear magnetic and electron paramagnetic spectroscopy.
• Optical and magnetic imaging. • Theoretical methods and computer simulations.
• Quantitative kinetic measurements using radiolabels, hydrogen exchange, stop flow and other methods.
• Electrokinetic methods such as electrophoresis, conductance measurements and patch clamping
• Peptide, nucleic acid and organic synthesis methods.
• Thermodynamic analysis using calorimetry and temperature and chemical denaturation.
• Molecular biology techniques such as cloning and high level expression of proteins
Biochemistry and biophysics is a rapidly developing area of biomedical sciences. New techniques, methodologies, and information continue to evolve at an ever-increasing pace. The graduate program in Biochemistry and Molecular Biophysics is designed to produce the next generation of scientists who will advance the frontiers of biological and medical science.
Admission for Ph.D. study is offered to students with good undergraduate training in biochemistry, physics, organic chemistry, physical chemistry, biology, and mathematics. Students lacking preparation in a particular field, but otherwise qualified, may be admitted and given the opportunity to strengthen their backgrounds by taking the appropriate courses. The Graduate Record Examination (GRE) General Test is required; GRE subject tests in biology, biochemistry, chemistry, physics or mathematics are recommended but not required. The Admissions Committee screens completed applications and decisions on admissions are based on undergraduate record, including research experience, GRE scores, letters of recommendation, and personal interviews. TOEFL scores are required for foreign students whose native language is not English. The BMB program especially encourages applications from minority students. Admission decisions are usually completed by late March. On-line applications can be accessed at http://www.med.upenn.edu/bgs/applicants_phd.shtml
Students accepted for admission into the Ph.D. program receive tuition, and health care and insurance reimbursement, plus a twelve-month competitive stipend. Awards are renewed annually for students in good academic standing. Support for graduate students comes from a variety of sources, including Biomedical Graduate Studies, training grants, faculty research grants, and from private foundations such as the Howard Hughes Medical Institute. Applicants are urged to apply for scholarships from the National Science Foundation and other funding programs for graduate students. A limited number of fellowships are available for outstanding foreign students.
The Biochemistry and Molecular Biophysics graduate program is designed to prepare students for careers as independent investigators and educators in the area of modern biochemistry and molecular biophysics. The curriculum has been designed to provide a superior graduate level education by tailoring the curriculum to each individual student in order to round out the student’s knowledge of biochemistry and molecular biophysics, while building on the strengths of the student and equipping the student for dissertation research. In addition to formal lecture courses, research seminars and informal interactions with other graduate students, post- doctoral fellows and faculty members form an important part of graduate education. The ability to make oral scientific presentations is an essential part of a scientific training, and is a required part of the program.
• Three semesters of Laboratory Rotations (BMB 699) are required and are to be completed during the first year. If needed, a fourth rotation may be taken in the second half of the summer after the first year. The first rotation may be carried out in the summer before the first year if a student chooses to matriculate early.

It is expected that in the first year, courses of a more general and foundational nature will be taken in order to give students a well-rounded and diverse background in the biochemical sciences. Subsequent lecture or seminar courses are designed to increase the student’s back- ground in more specialized areas. The three laboratory rotations ensure that first year students quickly become familiar with the variety of research opportunities available within the graduate program and so can choose a suitable thesis advisor. Full-time thesis research generally begins at the end of the second year, and students are encouraged to develop rigorous and creative approaches to examine significant problems in biology.
Many of the courses available to BMB students are taught in collaboration with other graduate programs or departments. Topics covered by these courses include molecular genetics of prokaryotes and eukaryotes, the structure and function of proteins and nucleic acids, molecular cell biology, biophysics of macromolecules, regulation of cell growth, membrane structure and function, virology, gene therapy, x-ray diffraction, and spectroscopy. A listing of all courses offered at the University is described in the University’s Course Register, which is online at http://www.upenn.edu/registrar
Combined Degree Programs
Students in the MD/PhD program typically follow these guidelines for the Ph.D. portion of their coursework.
Year 1 Medical School (spring) - One graduate course
Year 1 Medical School (summer) - One laboratory rotation
Year 2 Medical School (fall) - One graduate course or laboratory rotation
Year 3 (fall & spring) - Full time graduate program and Candidacy Exam
Years 4 - 6 - Full time dissertation
Eleven to fourteen credits may be transferred from the School of Medicine to complete the required elective credits.
Students in the VMD/PhD program generally follow the same guidelines as those in the MD/PhD program, although the full time graduate program for these students usually begins in the spring of Year 3.
Combined degree students are usually exempt from the third lab rotation. Students are advised by the Advising Committee of the BMB Graduate Group.
Course advising is the responsibility of the Advising Committee. In view of the exceptional diversity of the students in the program, the Committee reviews the background of each student, and in consultation with the student, decides on his or her curriculum. The goal is to provide a flexible yet structured program so students of diverse backgrounds will receive the appropriate training for their research interests.
Each incoming student meets individually with the Advising Committee during orientation week to select his or her fall courses, and at the end of December to select spring courses. A group meeting is held in early May to discuss summer lab rotations. Rising second year students meet individually with the Advising Committee mid-July to discuss fall courses and at the end of December to select spring courses, although some students may not need this second meeting if they have fulfilled all course requirements.
Students are assigned a faculty mentor as soon as they are accepted into the program. The role of the mentor is to provide informal advice on more general aspects of graduate education, such as adjustment to graduate life, guidance in career paths, and to advise a student in choosing a Thesis Advisor.
In addition to the regular advising provided by the Advising Committee, the Graduate Group provides extensive support for practical issues that may limit the productivity of students. The Student Affairs Committee organizes workshops on topics such as writing a thesis, applying for fellowships, and how to get the most out of your thesis committee.
Career Services provides a wealth of career information on its website. It works with all Penn students to help them define career goals through individual counseling and workshops on a wide range of topics from resume writing to interviewing to networking. It also sponsors on-campus recruiting sessions and maintains lists of job opportunities.
CANDIDACY EXAMINATION (see guidelines for 2013-14)
All graduate students affiliated with BGS (Biomedical Graduate Studies) are required to pass a Candidacy Examination in the spring of the second year. In BMB, this examination consists of both a written research proposal (in the style of an NIH fellowship application) and an oral defense of the proposal. Only students in good academic standing are eligible to take the Candidacy Examination.
Composition of Thesis Committees
Within approximately four months after passing the Candidacy Exam, the student must form a Working Thesis Committee. The Working Thesis Committee will be comprised of three faculty; at least two must be members of the BMB Graduate Group. The Chair of the Working Thesis Committe must be a member of the BMB Graduate Group. The first meeting of the committee should be held by December 31st of the second year in the program.
The Final Thesis Committee includes all members of the Working Thesis Committee plus one internal and one external examiner. At least three of the Final Thesis Committee members must be members of the BMB Graduate Group. The thesis advisor is not a member of the committee, but must attend all committee meetings and the open part of the defense. He or she may not participate in the deliberations of the thesis committee.
The External Examiner is someone from outside the University and outside the BMB Graduate Group who is brought in as an additional examiner for the thesis defense. If it is not possible for the External Examiner to attend the oral defense, he or she will be asked to provide a written report to the Chair of the student's thesis committee.
The Working and Final Thesis Committees should be constituted to include breadth as well as expertise in the particular research area of thesis work. The student and his or her advisor shall jointly select the members of the thesis committees. The student should submit in writing a list of potential committee members, indicating which faculty will serve as Committee Chair, to his or her Thesis Advisor and the Graduate Group Chair. The Graduate Group Chair will respond in writing to approve the composition of the Committee, or make recommendations for other candidates. The Graduate Group Chair will adjudicate any disagreement on the composition of the thesis committee. The student must register the composition of his or her thesis committees with the Graduate Group Office after approval by the Graduate Group Chair.
Evaluation of Student’s Progress
The Working Thesis Committee meets to monitor the students' progress every 6 months. The Thesis Committee is permitted and indeed encouraged to interview the student in the absence of the Thesis Advisor and vice versa. A written summary will be prepared after each meeting by the Thesis Committee Chair and will be placed in the student’s academic file. Upon written approval by the Chair of the Thesis Committee, the 6-month requirement may be waived, and yearly meetings held instead.
If the Committee and/or the Thesis Advisor are not satisfied with the student's productivity, a written report will be prepared by the Committee outlining a proposed course of action. A copy of the report will be forwarded to the Graduate Group Chair, the student and the Thesis Advisor. The student will have the opportunity to reply to the written report of the Committee. Within 6 months, an additional meeting of the Thesis Committee will take place to determine the progress. In the event that the student does not make sufficient progress, he or she will be placed on academic probation. If progress is not apparent by the next Committee meeting, the student will be asked to petition for a terminal Master’s degree.
Preparation of Dissertation
The Thesis Committee will give written approval for the student to begin to write the dissertation, but this does not automatically mean that experimental work is completed. The student should be prepared to continue experiments while writing and to rewrite or do additional experiments after the thesis defense if deemed necessary by the committee. If the student has not already done so, at this point he or she should, in conjunction with the Thesis Advisor, select the remaining two members of the Committee to form the Final Thesis Committee. A draft of the dissertation must be submitted at least two weeks in advance of the defense to minimize the possibility of unexpected problems. The Graduate School of Arts and Sciences (GAS) requires a dissertation to represent a definite contribution to scientific knowledge and to show that a student possesses "power of independent research." The Graduate Group feels that the dissertation should contain experimental information that answers a stated question and should display a logical progression of scientific thought. The main information contained in the dissertation should be of a caliber sufficient for publication in a reputable refereed scientific journal.
The thesis defense will take the form of a public lecture. The private portion of the defense will be conducted solely by members of the Thesis Committee and the Graduate Group Chair, and in the absence of the Thesis Advisor. The decision on approval of the thesis will be made solely by a consensus of the Thesis Committee in the absence of the student and the Thesis Advisor.
If a Thesis Committee member cannot attend the Defense, the student must meet with the Chair of the Graduate Group to discuss the circumstances and decide on a course of action. One possible outcome is that the missing Committee member must review the student's written dissertation and submit a critique to the chair of the Committee before the thesis defense, so that those comments and any questions can be included during the private portion of the defense and addressed in any revisions that may be made to the dissertation.
Students who are defending their theses must inform the Graduate Group Office at least two weeks in advance of the defense date, and supply the title of the thesis and place and time of the defense, as well as an abstract and a figure for the monitors announcing the defense. The Graduate Group Office will announce the thesis defense to the University community. The Graduate Group Office is responsible for completing the forms indicating that the thesis has been successfully defended. Before a student makes the appointment to deposit the thesis, he or she must provide the Graduate Group Office with a copy of the abstract page, a signed copy of the title page, and postdoctoral appointment information, if available.
Students should consult the "Graduation Checklist" as soon the Thesis Committee formally grants permission to write.
OTHER PROGRAM INFORMATION
The University standard for satisfactory academic progress is a 3.0 grade point average (B). The minimum standard for final course grades in the BMB Graduate Group is a "B". BMB student who do not achieve the minimum grade for courses will be referred to the Biomedical Graduate Studies Academic Standards Committee. The Academic Standards Committee will, in concert with the BMB Academic Review Committee's recommendations, impose sanctions such as academic probation. In addition, the Academic Review Committee may ask a student to retake a course, continue course work towards the terminal Master's Degree, or withdraw from the program. The Academic Review Committee will review each case on an individual basis.
The training program in Responsible Conduct of Research (RCR) has three major educational components: web-based training, program literature, and small group discussion workshops. Participation in all phases of the training program is mandatory for all graduate students in the Biomedical Graduate Studies programs. The training program begins with a brief faculty presentation to incoming students at the BGS new student orientation, which provides an overview of responsible conduct of research and appropriate behavior in the classroom and lab. New students are also given a copy of the Cold Spring Harbor publication, At the Bench (Kathy Barker, author) which covers some aspects of RCR. See the BGS website for further information: http://www.med.upenn.edu/bgs/rcr.shtml
Transfer of Credit
Students who enter the program having taken similar courses at the graduate level at other institutions may petition the Graduate Group for transfer of credits. The decision to approve transfer of credits will be made in writing by the Graduate Group Chair. Up to eight courses may be transferred. Students who have taken graduate courses at Penn through the College of General Studies (CGS) may apply to transfer up to four course units toward the Ph.D. degree. Combined degree students may transfer as many as 14 course units from another Penn professional or graduate program, but are required to take 8 course units of Ph.D. lecture courses and seminars. It is recommended that incoming students review any courses that may be transferable at their meetings with the Advising Committee in September.
Transfer from Other Programs
University of Pennsylvania students who are currently enrolled in another graduate group within BGS may be considered for transferring into the BMB Graduate Group. Students should express their interest in joining the BMB Graduate Group by writing a letter of intent to the Graduate Group Chair. The student will then meet with the Chair to review his or her academic record and establish a plan for meeting the BMB requirements. Students who wish to transfer from graduate groups outside of BGS need to follow the same procedures as regular applicants to the program.
Terminal Master's Degree
The BMB Graduate Group does not offer study towards a Master's degree. However, the Graduate Group may award a terminal Master's degree to students who choose not to continue in the Ph.D. program. In certain instances, the Graduate Group Chair may recommend that students who have not performed satisfactorily in course work, the Candidacy Examination, or dissertation research leave the program with a terminal Master's degree. The University requires a minimum of 8 course units for the terminal Master's degree. A final paper or master’s thesis may also be required, as determined by the Graduate Group Chair and Academic Review Committee.
Leaves of Absence
The University allows graduate students to take leaves of absence with the permission of the graduate group chair and the graduate dean. Students must write to the graduate group requesting the leave; if the chair approves, the request will be forwarded to the graduate dean (i.e., the BGS Director) for approval. The main types of leave are medical, family, and paid time off for the birth or adoption of a child. Under medical and unpaid family leaves, stipends are suspended during the leave period and are guaranteed upon return from leave under the conditions of the original award guarantee, i.e., as long as the student remains in good academic standing. Note that students who have passed the candidacy exam may need to arrange fellowship support from a mentor in order to return; there is no guarantee that the original mentor will be able to provide financial support when the student returns from leave. Students receiving NIH NRSA support in the form of a training grant appointment or individual fellowship must also obtain permission for a leave from NIH.
Students who wish to take a medical leave are expected to arrange for a letter from the treating professional(s) justifying the leave. The letter should be sent to the BGS Director. Students on medical leave are expected to seek and follow the advice of the graduate group chair or his/her designate to remediate any work and to devise a course of study for re-enrollment. Such students are also expected to make appropriate financial arrangements to continue any necessary treatment during the leave (e.g., payment for the Student Health Insurance plan), to continue treatment, and to arrange for an appropriate support system. In order to return from medical leave, students must arrange for treating professional(s) to provide documentation of treatment and progress. Students who take a leave for psychological reasons are expected to arrange evaluation with Counseling and Psychological Services (CAPS) four weeks prior to the sought return date.
BGS abides by the University’s policies for Family Leave and Time Off for Childbirth or Adoption. The University policies can be found at: http://provost.upenn.edu/policies/pennbook/2013/02/13/family-friendly-policies-for-phd-students
