Effective Winter 2022, students admitted to the major will declare one of three tracks: Bioinformatics, Biological Data Sciences, or Dynamical Modeling. These areas represent different domains of computational biology/technical computing. Each track has a list of courses related to that area that are more computational or quantitative in nature. Students will be required to take three courses from their chosen track’s course list. In addition to these three more computational courses, students will also take two courses from a list of life science courses. The life science courses are organized into different categories, including: neurosystems, genetics and molecular biology, ecology, epidemiology, physiology, and biochemistry. Students can take both life science courses within one of these categories, or take one course each in two different categories. The list of approved life science courses is the same across all three tracks, allowing students in any track to apply their computational coursework to any of these biological areas.

For students admitted to the major (not the pre-major) prior to 22W and forward, and following the previous concentration curriculum, more info on concentration requirements can be found here.

Additional Prep for the Major: (depending on chosen track)

The following courses do not have to be completed prior to admission into the major.

Bioinformatics Track: must also complete Computer Science 32; OR Program in Computing 10B and 10C.

Biological Data Sciences Track: must also complete Computer Science 32. MATH 61 and/or MATH 115A are also recommended pre-reqs for this track depending on chosen track courses.

Dynamical Modeling Track: MATH 32A is a recommended pre-req depending on chosen track courses.

All Tracks: LIFESCI 23L and/or CHEM 14C/30A are recommended pre-reqs depending on chosen Life Science courses.

NOTE: Additional pre-reqs (beyond the required and recommended courses above) may be required for certain track courses. Students should check pre-reqs on the Schedule of Classes.

Students also still have the opportunity to propose a Customized track.

Rationale for Revision

Why did CaSB shift from concentrations to tracks?

The main goals of the revision were to:

  1. Update the curriculum and tracks to better align with modern themes in computational and systems biology, as well as with the current administrative structure of UCLA.
  2. Add more flexibility to the major (by allowing students to choose from a list of courses rather than requiring specific courses) and better align requirements with what students are actually taking.
  3. Better ensure that all students take a mix of both computational and life science coursework.
  4. Reduce students’ time to degree by eliminating strict requirements of courses with hidden pre-requisites.
  5. Accommodate growth in the major by no longer requiring all students in a concentration to take a specific course, reducing reliance on and competition/demand for seats in individual courses offered by other departments, such as Computer Science and Statistics.
  6. Reduce the number petitions needed (for example, when a required concentration course is not being offered, has too few available seats, or will no longer be offered).

Who is held to the new requirements?

The tracks went live effective Winter 2022. If you have already been admitted (or are admitted prior to the start of Winter 2022) to the CaSB MAJOR, you will not be held to the new tracks. You will continue with your concentration. If you would rather switch over to one of the new tracks, please contact the CaSB Counselor to update your catalog term.

If you are currently in the CaSB PRE-MAJOR, you will be held to these new requirements, unless you are admitted to the major prior to the start of Winter 2022.

If you will be finishing your last pre-major requirements this Spring, Summer, or Fall, you are strongly encouraged to apply to the major as soon as your grades post. If you are admitted to the major prior to the first day of Winter Quarter (Week 0), you will not be held to the new requirements. Once Winter quarter officially begins, students admitted to the major will be held to the new requirements.

Check out this FAQ document and/or contact the CaSB Departmental Counselor.

Important Information

All major courses must be taken for a letter grade, C or better, with the exception of C&S BIO/COM SCI/BIOENGR M184 which is only offered on a Pass/No Pass basis.^
^CaSB made a temporary exception allowing pre-major courses taken between Spring 2020 and Summer 2021 to be taken for a Pass grade. More details on this exception can be found here.

Students must have a minimum 2.0 GPA in upper-division major coursework to graduate.

Students who receive a C- or below in a major course must either repeat the course or petition to have the lower grade count for the major. More information on petitioning can be found here.

Students are subject to any requirement changes in the major until they are officially admitted to the major.
