Objectives


Undergraduate Concentration

The undergraduate program in biology, leading either to the B.A. or to the B.S. 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 courses to advanced, specialized, graduate-level courses in many of these areas. The biology department has 26 full-time faculty members with teaching and research interests in the fields of genetics, molecular biology, development, immunology, neurobiology, motility, cell biology, and structural biology.

Since the interests and needs of our students vary, the concentration 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 concentration in biology provides excellent preparation for students intent on careers in biological research who want to go to graduate school, 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 and participates in a program for a residential semester in Environmental Science at the Woods Hole Biological Laboratory (see page 81 for details).

For M.S. and Ph.D. 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 an Undergraduate Concentrator


Students wishing to concentrate 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, or omit it and begin the biology series with Genetics and Molecular Biology or Cell Structure and Function (BIOL 22a (Formerly BIBC 22a) or b). During their sophomore year, students typically enroll in Organic Chemistry, Cell Structure and Function, and Genetics and Molecular Biology, with associated labs. While other course schedules are possible, the one described above allows students ample time to complete the remaining requirements (calculus, physics, and five biology electives) for the biology degree during the junior and senior years and leaves students the option of enrolling in Senior Research during the senior year. Exceptionally well-prepared students may enroll in Cell Structure and Function and/or Genetics in their first year.

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