Our undergraduate Microbiology program enrolls about 200 students and is the only Bachelors of Science degree in MB in Oregon. Microbiology majors study beneficial and disease-causing bacteria, archaea, viruses and parasites in the context of human, plant and animal disease and the environment. We offer two options for majors that wish to specialize. A Pre-Medicine Option helps students interested in a career in the medical field to prepare for professional school. The Aquatic Microbiology Option provides students interested in environmental sciences with a background in the microbial processes of aquatic systems and prepares them for careers in environmental resource fields in industry, government and academia.
