Bachelor of Science in Biological Sciences

The Bachelor of Science (BS) degree in Biological Sciences prepares students for a career as a professional biologist and is geared toward students who wish to enter post-graduate studies in any area of biology or one of the health professions (e.g., dentist, physician, optometrist, pharmacist, physician assistant, physical therapist, or veterinarian). Graduates are also well prepared for careers in private industry, with non-profit or government organizations, or teaching at the secondary level. To help foster student success, biology faculty provide high-quality academic and career advising throughout the student’s time at IU South Bend. Students receive a strong, up-to-date grounding in biology, and with a wide variety of elective courses, students are able to tailor their major toward their career goals.

The curriculum also educates students in the process of scientific discovery, with emphasis on reading scientific literature, writing about and presenting scientific information, designing scientific studies, and collecting, manipulating, and analyzing scientific data. Many students work closely with faculty on independent research projects that provide valuable laboratory and field skills and increase success in applications for post-graduate positions or jobs in the private sector. Students receive strong introductions to the cognate areas of chemistry, physics, and mathematics, and all Biological Sciences BS graduates may earn a minor in chemistry without taking additional courses, if they earn appropriate grades in the required Chemistry courses.

Academic Advising

Students planning to major in biological sciences should contact an academic advisor in biological sciences before their first semester to develop a plan for their academic course of study. College policy on advising requires that students meet with their academic advisors at least once each year; biology majors meet with their advisors prior to each semester’s enrollment. Advising holds are reset following advising appointments. To determine the name and contact information for your advisor, see One.IU.
