About the Bachelor of Science in Computational Biology
All undergraduates accepted to the School of Computer Science at Carnegie Mellon University are able to choose between four majors: computational biology, computer science, artificial intelligence, and humancomputer interaction. For more information on the different majors, please visit the School of Computer Science Undergraduate Programs Overview.
Success in computational biology requires significant technical knowledge of fundamental computer science as well as a broad biological intuition and general understanding of experimental biology. However, most importantly, it requires students who can integrate their knowledge by making connections between the two fields.
As much as any other field, making the interdisciplinary connections required to truly integrate biological and computational knowledge often requires a student to conduct research. We don't just encourage undergraduate research to our majors; we promise it to all students who are interested.
There is significant industry demand for excellent computational biology students, in biotech firms, biomedical research, as well as in pharmaceutical research. Both established companies and the hundreds of recent startups in this field struggle to find computationally sophisticated employees who have a strong foundation in the life sciences. By receiving their training in the worldfamous School of Computer Science, our students will receive a degree that is unparalleled at any other institution.
Students completing the major will also be ideally prepared for Ph.D. programs across a range of biomedical areas. Students who choose to complete premed requirements will be very wellprepared to attend medical school; the next generation of physicians will need to better understand the computational approaches needed for automated medical testing, automated medical imaging, and the revolution in personalized medicine.
Degree Requirements
Students completing the Bachelor of Science in Computational Biology follow certain policies that apply to all SCS students; please consult the SCS policies page for a complete listing of these expectations.
Students must complete a minimum of 360 units for the degree in computational biology.
The following degree requirements apply to undergraduates matriculating in fall 2020. For students in previous years of entry, please consult past CMU course catalogs.

Sample Course Sequence for Computational Biology Majors
The following is an example fouryear course sequence for computational biology majors. Note that our suggested courses during the first year fall are aligned with the sample course sequence for Computer Science majors. All students interested in computational biology should take 03151 (Honors Modern Biology) in their first fall and 02251 (Great Ideas in Computational Biology) in their first spring.
Some suggestions listed below are quite flexible. For example, physics and chemistry can be taken at any point in the student's first three semesters, and some of the computer science courses below can be replaced by other courses within the School of Computer Science, depending on a student’s individual interests.
Other courses, such as cell biology, biochemistry, computational genomics, and biological modeling and simulation, are only offered in either the fall or the spring.
We discuss a tailored plan with our majors to ensure that courses are taken at the appropriate times, while affording each student the flexibility to explore their other interests at CMU.
Year 1
Before you arrive at CMU, you will take 99101, Computing at Carnegie Mellon, and 15051, a Discrete Math primer, in your own time. These short courses are provided to incoming students for free.
