Membership in the ACA is open to any person who is actively interested in the purposes of the Association. The ACA welcomes everyone from students to retirees. All of our members contribute to the life and vigor of the Association.

Your membership helps the ACA share our scientific passions and accomplishments through different approaches, including the annual conference, our publications and educational outreach.

The ACA was established to connect scientists and anyone interested in crystallography and the ACA strives to continue to reach that goal today. As we progress forward the ACA remembers and memorializes our past crystallographic discoveries and achievements. It is with our history and achievements that the ACA hopes to inspire future generations of explorers, scientists and crystallographers.

As a student, let the ACA inspire you to dive into physics, math and chemistry. As a grad or undergrad let the ACA help you establish your professional network. Regular members share research, accomplishments and curate industry connections. Retired members help remember our history and encourage future crystallographers.
