Offered at: San Luis Obispo Campus
Microbiology is the study of bacteria, archaea, viruses, fungi, and protists. Microorganisms are ubiquitous in the environment as important contributors to nutrient cycling, and many have symbiotic relationships with other organisms. Species of medical importance impact human and animal health as pathogens associated with infectious diseases. Additionally, microorganisms are critical research tools in fields such as molecular biology and genetics, and are used for large-scale production of many foods, pharmaceuticals, and industrial chemicals. Cal Poly is one of the few public universities in California offering a laboratory-intensive Bachelor of Science degree in Microbiology.
In the junior and senior years, in addition to microbial genetics, majors can take specialized courses in virology, biotechnology, microbial physiology, medical microbiology, immunology, microbial ecology and computation in microbiology. Students also choose elective courses related to student interests and career goals in close consultation with their faculty advisors. Graduates may also pursue post-baccalaureate employment in applied areas such as industrial microbiology, food and dairy microbiology, biotechnology, public health, epidemiology, or medical laboratory technology. Students may not double major in Biological Science and Microbiology.
Program Learning Objectives
- Explain fundamental concepts and principles in microbiology and general biology (atom to ecosystem).
