ASU Biocollections

Supporting research, education and biodiversity science and discovery

Welcome to ASU Biocollections

The Center for Biological Collections and Discovery (ASU Biocollections) encompasses two complementary major collections, each with distinct missions and specialized holdings. While managed separately, the collections are united by shared scientific expertise and coordinated stewardship. Together, they support research, education, and long-term biodiversity science through collaborative leadership and complementary infrastructure.
