  • Combined major offered by the Department of Biology, College of Science and Engineering and the Department of Mathematics, College of Science and Engineering.

Introduction

  • Do you enjoy courses and tasks that have a computational focus?
  • Do you like applying mathematics and data analysis to solving real-world problems?
  • Are you intrigued by using models and simulations to understand complex phenomena?

Biology is an increasingly quantitative discipline, as computational power and biological datasets continue to grow. Mathematical models provide powerful tools for building a sophisticated understanding of complex biological phenomena. In this major, you will develop a strong background in biology along with a broadly applicable understanding of quantitative and computational approaches to problem-solving. You will gain skills that will prepare you to contribute to a wide range of fields such as biostatistics, biomathematics, bioinformatics, bioengineering, theoretical biology, ecology, evolutionary biology, and molecular biology. A diploma granted under this concentration will indicate “Bachelor of Science;” official transcripts will indicate Biology/Mathematics.

How to Declare (Admission and Declaration Process):

Category of Major : Capacity-constrained major

Declaration form: Student Academic Declaration and Change Form

Admission and Declaration Process

Admission to the Biology Major is based upon an application procedure that considers prior academic performance (specifically GPA in prerequisite courses) and student responses to focused prompts.

Pre-major Declaration

Students who have been formally admitted into Western may declare a biology pre-major at any time by filling out the Student Academic Declaration and Change Form. Pre-majors are assigned to biology faculty advisors in their area of interest and may expect to be notified regularly via email regarding opportunities for general advising, course registration information, application deadlines, and scholarships.

Application to the Major

Students are eligible to apply to the Biology Major when they have completed BIOL 204, BIOL 205, CHEM 161/175, and CHEM 162/176 with grades of C- or higher. Application involves submitting a completed application form, including responding to prompts about the applicant’s experience, motivation, and goals. See the Biology Department’s website for more details, including information about application prompts, application deadlines, review timeline, and reapplication limits. The Biology Department’s website also has information specific to transfer students interested in applying for admission to the Biology Major, such as application eligibility and transfer course equivalencies.

Students are strongly encouraged to apply to the major at the beginning of the quarter in which they are enrolled in BIOL 206 and/or CHEM 163/225 to ensure timely progress towards graduation. Admission to the major following a successful application is contingent on completing both BIOL 206 and CHEM 163/225 with a grade of C- or higher.

Grade Requirements

A grade of C- or better is required for a student’s major or minor courses, and supporting courses for majors and minors. A GPA of 2.50 or above in major is required.
