Membership 

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.

Membership Renewal

ACA members pay dues annually.

Renewing your dues on time each year ensures your ACA membership is continuous.  Members whose dues are not paid will be kept on the membership roster as "graced" for one year. During the new annual billing cycle such members will receive bills for the unpaid dues of the current year plus dues for the following year. Members still in arrears on January 1 of this second annual billing cycle will be dropped from the membership list.
