Objectives

Undergraduate Major
The undergraduate program in biology, leading either to the BA or to the BS degree, is designed to give students an understanding of fundamental and current biological knowledge in a variety of fields. The program offers a wide array of courses to undergraduates, ranging from introductory to advanced, specialized, graduate-level courses in many of these areas. The biology department has more than twenty-five full-time faculty members with teaching and research interests in the fields of genetics, molecular biology, development, cancer, immunology, neurobiology, motility, cell biology, structural biology, animal behavior, and ecology.

Because the interests and needs of our students vary, the major is designed to provide flexibility once the core courses have been completed. Students may elect undergraduate-level courses in a variety of areas of biology and biochemistry or may choose to obtain more-advanced, in-depth training in one particular area. Students are also encouraged to take advantage of opportunities to become integral members of research laboratories in the department and to attend departmental colloquia.

A major in biology provides excellent preparation for students intent on careers in biological research; for those seeking careers in medicine, veterinary medicine, and dentistry; and for those interested in the allied health professions such as public health, genetic counseling, physical therapy, or physician assistant. For those seeking courses concerned with ecology or environmental science, the biology department offers study in those areas. See "Special Note B" below for additional programs in those areas.

Graduate Programs in the Biological Sciences
For MS and PhD degrees in the biological sciences, see the separate listings for molecular and cell biology, biophysics and structural biology, neuroscience, and genetic counseling programs in this Bulletin.

How to Become a Major

Students wishing to major in biology should enroll in general chemistry during their first year. Students may elect to take BIOL 15b, an introductory course in biology, in the first year. Exceptionally well-prepared students may enroll in BIOL 22a (Genetics) in their first year.

Most students begin the biology series in their sophomore year and take BIOL 22a (Genetics) and BIOL 22b (Cell Structure and Function), plus BIOL18a and b labs. During their sophomore year, students can also enroll in CHEM 25a and b (Organic Chemistry), with associated labs.

Other course schedules are indeed possible, but students should note that some biology electives have a prerequisite of completion of CHEM 25a. Taking CHEM 25a and b in the sophomore year allows students to begin taking electives in their junior year, as well as to begin completing the remaining requirements for the BA or BS degree in biology. Students also have the option of enrolling in BIOL 93a (Independent Research) during their junior or senior year, and BIOL 93a/BIOL 99a or BIOL 99a and b (Senior Research) during the senior year.

To learn more about the biology major, students should attend one of the special departmental programs held each fall or consult with the undergraduate advising head.

A thesis submitted for the master's degree may also be submitted to the biology department for departmental honors. The master’s thesis must be deposited electronically to the Robert D. Farber University Archives at Brandeis.

Special Notes Relating to the Undergraduate Program

A. BIOL 18a and b (labs) and BIOL 22a and b will satisfy the general biology entrance requirements of most medical schools. 

B. Biology majors wishing to study ecology, conservation, and marine studies may wish to look into the environmental studies program described in this Bulletin, as well as the following programs:

Semester in Environmental Science at the Marine Biological Laboratory in Woods Hole: Five courses are offered each fall as part of a residential program, including the analysis of terrestrial and aquatic ecosystems, microbial and animal ecology, global issues, and ecological modeling. Every student must do an independent research project during the semester. Up to four semester course credits may be earned toward the Brandeis degree and two semester course credits may be counted toward the biology BA or BS elective requirement.

Denmark's International Studies Program: DIS offers a range of programs in marine biology and ecology, environmental biology, medical practice and policy, and molecular biology and genetics.

School for Field Studies: SFS offers programs at a number of different sites around the world, including East Africa, Costa Rica, Baja Mexico, Australia, and the West Indies.

School for International Training: SIT offers programs around the world in ecology, conservation, and sustainable development.

Students should see Mr. D.L. Perlman for further information on these programs, including information on the transferability of course credits as biology electives.

C. Biology majors who wish to enroll in PHYS 11a and b (Basic Physics), rather than PHYS 10a and b (Physics for the Life Sciences), must complete both MATH 10a and b as prerequisites.

D. AP exam credit: Students receiving AP credit as per university guidelines may use these to satisfy the general chemistry (CHEM 11) or physics (PHYS 10, 11) requirements. However, neither AP Math AB scores of 4, 5 nor AP Math BC scores of 3, 4, 5 may be used to satisfy the quantitative course requirement for the biology major.
