Do you love animals and aspire to engage with coursework, laboratory and field research relating to diverse animal species, habitats and ecosystems? Then zoology is the right major for you. The zoology major — the only one in the state of Oregon— is housed in the nationally ranked Department of Integrative Biology in the School of Life Sciences. As a zoology major, you will study a broad range of core courses providing a solid foundation in biological sciences as well as elective courses in the diversity, organismal biology, ecology and evolution of animals to match your specific interests in animal biology. Zoology students are actively engaged in laboratory and field research, working alongside faculty in a variety of projects, including amphibian declines in the Cascade Mountains, the disease ecology of African ungulates and discoveries of new beetle species in Oregon. The zoology program will prepare you well for jobs in a variety of fields, such as animal care and husbandry, curatorial and museum management, laboratory animal research, field biology and conservation, and environmental management and policy, as well as graduate programs related to the biology of animals.

"In six days, we treated 767 dogs, cats, pigs, cattle, and horses. I was given the freedom to do the physical exams myself, listening to heart and lung sounds and palpitating lymph nodes.”
Karianna Crowder ( Zoology '17) worked at a pet clinic in Nicaragua during one of several study abroad programs that she embarked on at OSU.
