With a strong foundation in biology, you can discover breakthrough treatments for rare diseases in developing countries, help children as a pediatrician in your hometown or research endangered birds in the Amazon.
Program Overview

Study biological organization from molecules to ecosystems.
Understanding life forms—from molecules and cells, to organisms and ecosystems—has never been more critical or more sought after and biology is at the center of it all. In the Biology program at Western Colorado University, you can work closely with your advisers to choose a variety of courses to create a self-designed major in areas such as botany, zoology, molecular ecology and integrative biology. This allows you to integrate the study of structure and function at all levels of biological organization from molecules to ecosystems.
To get hands-on experience, you can collaborate with researchers at the world-renowned Rocky Mountain Biological Laboratory and conduct original research at the Thornton Biology Research Program. Our state-of-the-art lab facilities, immersive learning opportunities and customized curricula enables you to get a head start on your career in public health, veterinary medicine, wildlife preservation and pharmaceuticals.
