Our diverse faculty includes thirteen professors with Ph.D.s in areas ranging from platelet cell biology to ornithology.

Our focus is to provide a well-rounded science education and encourage learning outside the classroom. We hope that you will find a home within the Biology Department at Augustana and take advantage of our small class sizes (8-30 students for upper-level classes), careful advising, and faculty who challenge students — as well as nurture and support them.
