Provisional University Bulletin (2026-2027)

• Major (BS)

The undergraduate major in biological physics is designed for students who want to apply physics and mathematics to the study of biological systems. In addition to the core physics curriculum, the program provides the quantitative skills and background in chemistry and biology for students interested in the study of the physics of biological systems, especially on the molecular scale. This program provides a strong foundation in the physical sciences that underpin much of the modern revolution in biology. It should be of particular interest to students wishing to pursue careers in fundamental or applied research in biophysics, quantitative biology, and biotechnology.

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

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.

In the years it is offered QBIO 11a (Nature's Nanotechnology) is recommended for first-year students as an introduction to the major. 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.

Degree of Bachelor of Science

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; PHYS 39a; PHYS 40a
Mathematics: MATH 10a,b (if possible it is highly recommended to also take Math 15a ,b)
Chemistry: CHEM 15a,b (or CHEM 11a,b) and CHEM 19a,b (or CHEM 18a,b)
Biology: BIOL 14a, BIOL 15b and BIOL 18a,b. Other lab courses may be substituted for BIOL 18a,b upon approval by UAH.
Biological Physics: QBIO 11a or PHYS 105a

QBO 11a (Nature's Nanotechnology) should be taken in the first year, if it is offered. Students who enter the program after their first year may find it convenient to replace QBIO 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.

Foundational Literacies: As part of completing the Biological Physics major, students must:

• Fulfill the writing intensive requirement by successfully completing one of the following: BIOL 18a or PHYS 39a.
• Fulfill the oral communication requirement by successfully completing: BIOL 18b or PHYS 39a.
• Fulfill the digital literacy requirement by successfully completing one of the following: PHYS 19a or PHYS 19b.

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 biomolecules. Electives: BIOL 102b, BCHM 171b*, BIBC 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: BCHM 101a*.

Modeling of biological structure and function: The development and analysis of mathematical models for elucidating biological structure and function. Electives: BIOL 107a, BIOL 135b, PHYS 105a, NBIO 136b, NPHY 115a, QBIO 110a.

Systems and networks: Study of topics including bioinformatics, neural networks, and networks of genes and proteins. Electives: COSI 178a, NBIO 140b.

Biophysical research skills: EL 24b.

*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: QBIO 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 14a; BIOL 15b; PHYS 39a
Year 4: PHYS 31a; two electives

Students with advanced preparation might choose additional courses in other areas rather than organic chemistry 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 14a; QBIO 11a; PHYS 11a,b or PHYS 15a,b; PHYS 19a,b
Year 3: BIOL 18b; BIOL 15b; PHYS 20a; PHYS 40a; one elective
Year 4: PHYS 31a; 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.

No course with a final grade below C- can count toward fulfilling the major requirements in Biological Physics.

No course taken pass/fail may count toward the major requirements.

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.

Students majoring in biological physics may not count required courses toward a minor in physics. By completing other required courses, they can complete a second major in physics. However, for the preparation for a career in biological physics, it might be more valuable to devote extra science courses to deeper preparation in chemistry and biochemistry.
