As a Lewis & Clark biology major, you will do biology: you will generate hypotheses, design studies, collect data in the lab and the field, analyze and interpret them, and communicate your findings through talks, posters, and papers. We think this is the best possible training for a career in biology and the best way to become a scientifically literate citizen. Our curriculum embraces all of biology, from molecules to ecosystems, and draws on other fields, like chemistry, mathematics, and psychology. Students and faculty work together, both inside and outside of class. You will learn to write grants, read scientific literature critically, reason quantitatively, and work in teams. Diverse natural environments provide abundant opportunities for fieldwork. You will have access to cutting-edge tools in microscopy, physiology, computational biology, and molecular biology. Those interested in health careers benefit from our proximity to Oregon Health and Science University.


  • You don’t just choose a major and stick only to that. You learn so much about every discipline, and I think that is a really valuable skill.

  • Lewis & Clark has helped me view my own path more as an adventure, rather than a structured series of events, both in academics and life in general.

  • Working with and leading trips for College Outdoors is an excellent complement to the classroom because it has offered me professional experience and ways to develop as a leader and outdoors person that I might not have been granted otherwise.
