Microbiologists study the way that microscopic organisms—bacteria, viruses, and fungi—function, evolve, and cause disease. The Microbiology B.A. degree may be a good choice if you are interested in microbiology and want to develop a foundation in science while getting a chance to explore other academic disciplines.
The Microbiology B.A. is offered through the Department of Biology, part of the College of Arts and Sciences. The department includes expert faculty who specialize in a wide range of disciplines within the biological sciences.
The Microbiology B.A. degree is suitable for students who are double majors as well as those individuals whose career goals include being a laboratory technician or working in an outside field, such as business, or environmental studies.
The biology department offers two microbiology degrees: the Bachelor of Arts in Microbiology (B.A.) and the Bachelor of Science in Microbiology (B.S.). The two degree options begin similarly, making it easy to adjust your path as your interests develop.
The department also offers two biology degrees: the Bachelor of Arts in Biology (B.A.) and the Bachelor of Science in Biology (B.S.), as well as a minor in Biology.
The Microbiology B.A. is one of the more flexible degrees offered by the biology department. It provides students with training in the major subject areas of microbiology, while giving them the chance to explore other academic disciplines.
The Microbiology B.A. has minimal chemistry and math requirements, allowing students to double major or purse additional minors. The Microbiology B.A. does not automatically fulfill most of the requirements for entrance to medical, dental, or optometry schools or to most graduate programs in microbiology.
If you wish to establish a rigorous background in the sciences that will prepare you for graduate or professional school in microbiology for science-related jobs, the Microbiology B.A. degree may be a good choice for you.
Students pursuing the Microbiology B.A. degree begin by taking an introductory biology lecture, BIOL-L 112 Foundations of Biology: Biological Mechanisms.
It is important for you to begin the chemistry sequence required for the Microbiology B.A. major when you are a freshman or sophomore, since a foundation in chemistry is required for a majority of intermediate and upper-level microbiology courses.
You may work with one of the Biology 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 Chemistry department's website.
To be successful in the Microbiology major, it is important not to take too many science and math courses per semester. Talk with one of the Biology academic advisors about how to balance your science course load.
Tracks and concentrations
The Microbiology B.A. degree gives students the opportunity to explore different areas within the field of microbiology as well as other academic disciplines. As a Microbiology B.A. major, you have the freedom to take upper-level courses from many different areas of microbiology, shaping your degree according to your interests.
The Microbiology B.A. does not have official areas of concentration, but students who are interested in a particular facet of microbiology may choose to take several upper level classes in that area. These include:
- Medical microbiology
- Prokaryotic microbiology
- Eukaryotic microbiology
- Ecological and environmental microbiology
This way, you acquire a more coherent education in a specific area of microbiology. Your introductory courses help you determine which (if any) specific area of interest to pursue.
Upper level coursework
All microbiology majors have the opportunity to take upper level courses in microbial ecology, genetics, microbiology, cellular, developmental, environmental, and molecular biology.
Keep in mind that you will need a strong foundation in inorganic and organic chemistry in order to successfully progress through your intermediate and upper level microbiology courses.
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.
Microbiology B.A. majors most commonly pursue the following additional degrees: Chemistry, Biochemistry, Psychology, Environmental and Sustainability Studies, or Spanish.
Common minors for microbiology 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.
- Enhance your major
Working with faculty
When pursuing a degree in microbiology, 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.
You can get involved in research as early as your first year. Many incoming first year students apply to the Arts and Sciences Undergraduate Research Experience (ASURE) program. ASURE students experience project-based learning enhanced by a community of supportive faculty and peers. Choose an ASURE path in the arts and humanities, social and historical studies, or natural and mathematical sciences. Consider joining one that will deepen your skills and knowledge in an area related to your major or a different one to become a more well-rounded thinker.
Other programs such as the Integrated Freshman Learning Experience (IFLE) or Science, Technology, and Research Scholars (STARS) program 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.
Many exciting research opportunities are available to Microbiology majors at IU Bloomington. Interdisciplinary research in biology and microbiology takes place in Indiana University facilities such as the Indiana Molecular Biology 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. You are encouraged to work with a faculty member who specializes in what most interests you.
Students can receive academic credit for their involvement in research through signing up for Independent Study credit hours. See the Biology department website for more information.
Biology students have the unique opportunity to gain teaching experience through becoming an Undergraduate Teaching Assistant (UTA). Students may earn either academic credit or be paid for their UTAship.
Visit the Biology department website for more information on undergraduate research opportunities, UTAships, and the Biology faculty's areas of research expertise. The academic advisors also post relevant research opportunities on the Biology blog.
Outstanding students may earn honors in Microbiology by writing and defending an honors thesis on their own original research. Students work with a faculty mentor to develop their research project, write their thesis, and assemble their thesis committee.
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-X490 Research in Biology devoted to their original project. Students who successfully complete and defend their honors thesis before their thesis committee receive honors in microbiology upon graduation.
