An outstanding foundation for future careers in microbiology and healthcare

Microbes and small organisms are at the center of many of the world's most urgent health and environmental problems. As a microbiology student, you can be a part of the pioneering study of bacteria, viruses and parasites to address environmental, medical and molecular biological problems and create new resources for a healthy planet. Through our biohealth sciences major, you can be prepared for a future as a healthcare provider, taking specific courses tailored to the track you choose.

Find your path

We offer two undergraduate majors: microbiology and biohealth sciences. As the only degree of its kind in the state of Oregon, microbiology majors get to dive into the study of beneficial and disease-causing bacteria, archaea, viruses and parasites in the context of human, plant and animal disease and the environment. The biohealth sciences major offers an interdisciplinary program designed to prepare students for diverse and vital careers concerned with healthcare, with options available for students who wish to enter medical, pharmacy, dental or other health-related careers.


Microbiology and biohealth sciences advising is organized around the conviction that you should be actively engaged in your education, as well as the planning and decisions needed to reach your professional goals. From the beginning, our advisors focus on your educational and professional goals, and they work with you to suggest opportunities that are important to being successful in those goals.
