Undergraduate Catalog 2026-2027

Biology, Bachelor of Science (525)

Department website: http://www.wku.edu/biology


Program Coordinator

Douglas McElroy, doug.mcelroy@wku.edu, (270) 745-2405

The major in Biology (525) provides students the opportunity to undertake an in-depth study of biological sciences and its applications. A minor, second major, or certificate is not required. The major in Biology begins with foundation classes and laboratories that build into a core of advanced courses and laboratories. In addition to a required core, students complete a range of biology elective courses tailored to their interests to support their career goals.

The program offers seven different concentrations - Applied Genetics (BIAG), Applied Microbiology (BIMI), Animal Physiology & Behavior (BIAP), Ecology, Wildlife, & Conservation (BIWC), Integrative Biology (BIIB), Molecular Biotechnology (BIMB) and Pre-Medical Professions (BIPM). These seven concentrations are designed to facilitate essential requirements and provide training for a variety of career pathways and advanced degree programs to suit students' interests.

In addition to coursework, students may apply up to six credit hours of faculty-guided independent research and/or an internship experience towards their degree.

Concentrations

  • Applied Genetics (BIAG)
  • Applied Microbiology (BIMI)
  • Animal Physiology and Behavior (BIAP)
  • Ecology, Wildlife, & Conservation (BIWC)
  • Integrative Biology (BIIB)
  • Molecular Biotechnology (BIMB)
  • Pre-Medical Professions (BIPM)

Program Requirements (54 hours)

This option for a major in biology requires a minimum of 54 hours in biology including 29-30 hours at the 300 or higher level. No minor is required. A range of upper-level courses are aligned with six concentrations offered within the major.

A baccalaureate degree requires a minimum of 120 unduplicated semester hours. More information can be found at www.wku.edu/registrar/degree_certification.php.

Students who began WKU in the Fall 2014 and thereafter should review the Colonnade requirements located at: https://www.wku.edu/colonnade/colonnaderequirements.php.
