BA in Biology—Behavioral Biology Specialization

The major in Biology with a specialization in Behavioral Biology (SBB) offers students the opportunity to develop an integrative and individualized curriculum bridging coursework in behavioral science in the Department of Biology with complementary classes in behavior taught in the Department of Anthropology and the Department of Psychological & Brain Sciences. The specialization builds upon instruction in the fundamental principles of the organization of behavior through integrated coursework in biology, biological anthropology, and psychology, spanning non-human animal behavior and human behavior across multiple levels of analysis. The interdisciplinary nature of the specialization affords broad knowledge and deep insight into the evolution and ecology of behavior and its hormonal, neural, and genetic mechanisms, and prepares students for postgraduate study in basic and biomedical research. Flexibility in course selection enables students to pursue individual interests and engage in undergraduate research.

Requirements

The specialization in Behavioral Biology requires a total of 12 courses in biology, anthropology, and psychology. Students must also complete a total of six to seven related courses in chemistry, mathematics/computer science, and physics.

Beyond Introductory Biology, at least three major courses must be at the 300+ level and three major courses must be lab courses taken in the BU Biology Department (the 300+ and lab requirements can overlap).

A grade of C or higher is required for major credit in all courses except corequisite chemistry courses. A grade of C– or higher is required for major credit in corequisite chemistry courses.

Course titles and full descriptions are located in the Courses portion of this Bulletin.

Note: After introductory biology, a minimum of five courses must be taken in the BU Biology Department (i.e., have a CAS or MET BI or BI cross-listed course designation). A maximum of four MET courses may be counted as credit toward the BA degree. In addition, at least three courses must be at the 300+ level and three must have a laboratory component. Some of these requirements can overlap (e.g., BI 315 simultaneously counts as a breadth requirement, a 300+ level course, and as a lab toward the three-lab requirement). Nonetheless, it is counted only as a single course toward fulfillment of the major.

Related Requirements (6–7 courses)

Chemistry

Choose one of the following tracks (in consultation with your major advisor):

Standard track (recommended):
  • Choose one of the following general chemistry sequences:
Sequence I Sequence II Sequence III

Please check the Study Abroad web page for prerequisites and additional information.

Undergraduate Research in Biology

While research is not required by the major, undergrads are encouraged to participate in research during their time at Boston University. Undergraduate research courses are available at all levels and require students to submit an application and receive approval by the Director of Undergraduate Studies.

Notes: Up to two 4-credit semesters can be used to fulfill major electives (these semesters do not need to be taken consecutively). One of these two semesters can be used toward the three-lab requirement. Both 2- and 4-credit research count toward graduation credits.

Honors Research in Biology (CAS BI 401 & 402) requires an overall GPA of 3.5. Students must complete two semesters of 4-credit research and one semester of the Honors Seminar (CAS BI 497/498). Honors students must complete and defend a written senior thesis.
