Biology majors begin by taking two introductory Biology lecture courses:
- BIOL-L 111 Foundations of Biology: Diversity, Evolution, and Ecology
- BIOL-L 112 Foundations of Biology: Biological Mechanisms
These are followed by BIOL-L 113, the introductory Biology Lab.
Because a significant amount of chemistry coursework is required for the Biology B.S. degree, it is important that you begin taking chemistry courses as soon as possible. You may work with one of the academic advisors to determine which beginning chemistry course is appropriate for you (either CHEM-C 103 or CHEM-C 117/127), or you can take the C117 Eligibility Quiz yourself on the website for the Department of Chemistry.
To be successful in the Biology B.S. major, it is important to limit the number of science and math courses that you take each semester. Talk with one of the academic advisors about how to balance your course load.
Tracks and concentrations
Students can choose to pursue either a general Biology B.S. degree, or a Biology B.S. degree with an area of concentration. There are three areas of concentration for you to choose from:
- Biology of Disease
- Cell Biology and Molecular Genetics
- Integrative and Organismal Biology
The fundamental goals of the areas of concentration are the same as those of the general Biology B.S. degree, but choosing an area of concentration will allow you to acquire a deep and coherent education in a specific area of biology. Your introductory courses will help you determine which (if any) area of concentration to pursue.
Upper level coursework
All Biology majors complete 18 to 20 credit hours of core classes in biology, which include courses such as molecular biology, genetics, and evolution. Biology B.S. students also are required to take inorganic and organic chemistry and physics. Keep in mind that you will need a strong foundation in chemistry in order to successfully progress through your intermediate and upper-level biology coursework.
Biology students get to choose many of their upper-level biology courses. Upper-level biology lectures and labs are offered in the following areas: microbiology, biotechnology, biochemistry, ecology, the environment, zoology, and botany. See the list of approved upper-level lectures and labs for course titles.
If you choose to pursue an area of concentration, then you will be required to pick 4 upper-level lectures, including an advanced skills course, and 2 upper-level labs from the approved lecture/lab list for that concentration. If you decide to do the general Biology B.S. degree, then you get to pick 3 upper-level labs and 3 upper-level lectures from the comprehensive list of approved upper-level lectures and labs.
Students interested in continuing their education overseas may want to participate in the Tropical Biology overseas study program (BIOL-L 433) led by IU Biology faculty members. The program is held in Costa Rica over winter break and in the Cayman Islands in the spring. You earn credit for one upper-level biology lab in the general Biology B.S. degree by participating in one of these programs. Talk to an Overseas Study advisor or visit the Overseas Study website for more information.
Commonly pursued majors, minors and certificates
With the help of your academic advisor, you may be able to combine several areas of interest with additional majors, minors, or certificates. Biology B.S. majors most commonly pursue the following additional degrees: Neuroscience, Psychology, Animal Behavior, Chemistry, Biochemistry, Human Biology, or Spanish.
Common minors for biology students are psychology, animal behavior, chemistry, social science and medicine, medical sciences, biotechnology, anthropology, and Spanish (or another language). Check your bulletin for more information about these minors.
Working with faculty
When pursuing a degree in Biology, you have the opportunity to work with faculty who have expertise and experience in the field. Take advantage of office hours to talk with your instructors about your performance in class, the content of assignments, and how the course helps you work toward your goals.
Many exciting research opportunities are available to Biology majors at IU Bloomington. Interdisciplinary research in biology and microbiology take place in Indiana University facilities such as the Biocomplexity Institute, the Center for the Integrative Study of Animal Behavior (CISAB), and the Center for Genomics and Bioinformatics. The nearby Research and Teaching Preserve provides a setting for field-based research in ecology and environmental issues.
A large number of students choose to pursue research positions in faculty labs. Through working in a lab, you get to participate in cutting-edge research, explore your own research interests, build relationships with faculty members, and gain valuable work and research experience.
Students can receive academic credit for their involvement in research by signing up for BIOL-X 490 Independent Study credit hours. See the Biology Department website for more information on ways that you can earn independent study credit.
Undergraduate Research Programs such as the Integrated Freshman Learning Experience (IFLE) and the Science, Technology, and Research Scholars Program (STARS) give students who are especially interested in research the opportunity to start working in a lab as early as their freshman year. Students in IFLE begin research the summer before their freshman year.
You are encouraged to work with a faculty member who specializes in what most interests you. For more information about the exciting research underway in the Department of Biology, visit the department's faculty and research webpages. The academic advisors post relevant research opportunities on the Undergraduate Biology blog.
Biology majors have the opportunity to gain teaching experience by becoming an Undergraduate Teaching Assistant (UTA). Introductory biology courses, especially BIOL-L 111 and BIOL-L 112, are large classes with discussion groups; UTAs help to create a small class atmosphere inside a large course. Students may either earn academic credit or be paid for their UTA experience.
Visit the website of the Department of Biology for more information on undergraduate research opportunities, UTAships, and faculty areas of research expertise.
Outstanding students may earn honors in biology by writing and defending an honors thesis on their own original research. Students work with a faculty mentor to develop a research project, assemble a thesis committee, and write their thesis.
To be eligible for departmental honors, students must have conducted their own research over at least two semesters and earned at least 6 credits of BIOL-X 490 devoted to their original project. Students who successfully complete and defend their honors thesis before their thesis committee receive honors in biology upon graduation. Talk with the academic advisors and the faculty for more information.
High achieving students may be recognized for Academic Excellence in the College of Arts and Sciences, or be eligible for admission to the Hutton Honors College.
