An interdepartmental program in Biological Physics
Last updated: August 23, 2011 at 3:28 p.m.
For a related graduate program, please see the Biophysics and Structural Biology Program elsewhere in this Bulletin.
The Biological Physics major offers students the unique opportunity to prepare for graduate school, medical school, or employment in biotechnology. This is an interdisciplinary major that brings together the disciplines of physics, chemistry and biology, with a particular emphasis on physics. Our undergraduate program is firmly based on a first‐rate research program in biophysics, an area of science for which Brandeis is world renowned. A particular strength of the program is that it offers numerous opportunities for cutting‐edge research in biophysics in a number of different labs on campus. In many instances students have published papers in prestigious journals while completing the major.
Core Skills
After completing this major, students will:
Given an observation about the living world, be able to formulate a hypothesis about the physical and chemical principles that give rise to it, produce a mathematical model that embodies these principles, and propose new experiments to test the hypothesis. Evaluate measurement errors in scientific data sets, the effects of these errors on interpretation of the data, and calculate levels of confidence in conclusions drawn from the data. Explain to an interdisciplinary audience the physical and chemical principles that underlie our understanding of the living world. Know how to design experiments, computer simulations, and/or theory to test a scientific hypothesis. They will also have developed their skills in applied mathematics, laboratory techniques, and in oral and written presentation.
Knowledge goals
After completing this major, students will have learned at an advanced undergraduate level the principles and practice of physics, chemistry and biology, as well as statistics and error analysis applied to experimental data. The goal is to become conversant in all three disciplines of science, with a particular emphasis on the mastery of physics as it applies to problems in the biomedical fields.
Upon Graduation
Most of our graduates go on to graduate school in biophysics, bioengineering and related interdisciplinary fields, while others go into high‐tech employment, medical school, or other professional studies.
Social Justice
One of the great challenges facing our society is the need for new sources of clean energy, better medicines, and new breakthroughs in basic science that will fuel the technologies of the future. These challenges will require the concerted effort of scientists from different disciplines working together toward a common goal. One of the key goals of the Biological Physics major is to produce a cadre of scientists that will be able to successfully work in interdisciplinary teams of tomorrow.
The major requires a large number of science courses, some of which are prerequisites for more advanced courses. Therefore, it is important to start taking these courses in the first year. Students are advised to meet with the biological physics chair as soon as possible to plan their schedule. It is most advantageous to take physics and math in the first year, but starting with chemistry and math in the first year is also adequate.
FYS 11a (Nature's Nanotechnology) is recommended for first-year students, but can be taken in the second year. Students interested in the honors program, involving a senior research thesis, should begin to seek a faculty mentor by the end of their second year, with the prospect of starting research as early as possible.Jané Kondev, Chair

To satisfy the requirements for the major in biological physics leading to the degree of Bachelor of Science, students must successfully complete the foundation of this program, which is a set of required courses in the physical and life sciences. The core courses, divided by fields, are:
Physics: PHYS 11a,b or PHYS 15a,b; PHYS 19a,b; PHYS 20a; PHYS 31a (formerly PHYS 30b); PHYS 39; PHYS 40
Mathematics: MATH 10a,b
Chemistry: CHEM 11a,b and CHEM 18a,b or equivalents
Biology: BIOL 18a,b and BIOL 22a,b
Biological Physics: FYS 11a
FYS 11a (Nature's Nanotechnology) should be taken in the first year. Students who enter the program after their first year may find it convenient to replace FYS 11a with PHYS 105a (Biological Physics), which covers the same material at a higher level of both mathematics and physics.
Students with high enough Advanced Placement Examination scores may place out of some of the elementary courses. See the Advanced Placement Credit chart in an earlier section of this Bulletin for details concerning the equivalent Brandeis courses for sufficient scores in the tests in Mathematics (AB or BC), Physics (C), and Chemistry. Credit toward the major is given for all these tests except for Physics C: Electrical. Students who take advanced placement credit for PHYS 15b will be required to take PHYS 30a, the intermediate-level course in this subject.
Beyond the core curriculum, students are expected to explore areas of further inquiry by taking at least two elective courses. Possible topics and related courses are listed in the following sections. Other courses can be taken as electives with approval of the program advisor.
Molecular structure: The use of physical techniques including X-ray diffraction, electron microscopy, and nuclear magnetic resonance to elucidate the structure of bio-molecules. Electives: BIOL 102b, BCHM 171b*, BIOL 126b, BCHM 104b*.
Single molecule biophysics: The study of biological processes on the single molecule scale, such as enzyme function, ion transport through membranes, protein folding, molecular motors. Electives: BIOL 25a, BCHM 101a*.
Modeling of biological structure and function: The development and analysis of mathematical models for elucidating biological structure and function. Electives: BIOL 135b, CHEM 144a, PHYS 105a, NBIO 136b, QBIO 110a.
Systems and networks: Study of topics including bioinformatics, neural networks, and networks of genes and proteins. Electives: BCHM 170b*, COSI 178a, NBIO 140b.
*Required prerequisites for this course are not included in the core curriculum.
A student starting the biological physics major in the first year, with no advanced placement, should follow the recommended sequence:
Year 1: FYS 11a; MATH 10a,b; PHYS 15a,b; PHYS 19a,b
Year 2: CHEM 11a,b; CHEM 18a,b; PHYS 20a, PHYS 40a
Year 3: BIOL 18a,b; BIOL 22a,b; PHYS 39a
Year 4: PHYS 31a (formerly PHYS 30b); two electives
A student with advanced preparation in math, physics, and chemistry who wants to emphasize biochemistry might take the following program:
Year 1: FYS 11a; MATH 15a; MATH 20b; PHYS 19b; PHYS 20a; PHYS 40a
Year 2: BIOL 18a,b; BIOL 22a,b; CHEM 25a,b; CHEM 29a,b
Year 3: BCHM 100a; PHYS 39a, one elective
Year 4: PHYS 30a; PHYS 31a (formerly PHYS 30b); one elective
Students with advanced preparation might choose additional courses in other areas rather than organic and biochemistry. A student who has started as a premed and switched to biological physics (not completing the premed program) might have the following program:
Year 1: CHEM 11a,b; CHEM 18a,b; MATH 10a,b
Year 2: BIOL 18a; BIOL 22a; FYS 11a; PHYS 11a,b or PHYS 15a,b; PHYS 19a,b
Year 3: BIOL 18b; BIOL 22b; PHYS 20a; PHYS 40a; one elective
Year 4: PHYS 31a (formerly PHYS 30b); PHYS 39a; one elective
In addition to the required courses, students are urged to learn the necessary topics in organic chemistry as preparation for biochemistry. This opens up additional options for undergraduate research and graduate programs in the life sciences. For medical school, a year of organic chemistry with laboratory, in addition to the required courses for biological physics, will complete the premed program requirements.
An important component of the program is the opportunity for students to participate in research. Opportunities exist for research in the laboratories of physics, chemistry, neuroscience, biochemistry, and biology faculty.
Honors Program
Graduation with honors requires completion of a senior research thesis. Students must enroll in BIPH 99d in their senior year to carry out a research project. Students wishing to join the honors program should apply to the honors advisor in the program in the spring of their junior year.
