Membership Renewal is Open!

Crystallography and structural science have been and continue to be on the forefront of major discoveries in the life sciences, medicinal chemistry, and materials science. The American Crystallographic Association, Inc. (ACA) is the home for over 1,000 structural scientists all over the world who are united by the common purpose to “promote interactions among scientists who study the structure of matter at atomic (or near atomic) resolution”.  

The annual ACA membership renewal period for 2022 is open and new members are always welcome to join!   Annual dues allow us to share our scientific passions and accomplishments through different approaches, including the annual conference, publications and educational outreach.

Donate

Without the continued support from our members the ACA could not continue to exist. Not only do your donations help the ACA operate on a day-to-day basis but they support our publications as well as educational and outreach activities. Opportunities to add donations onto your dues are included when you renew or join.  

The 71st ACA Annual Meeting: Abstract Archive Now Available!  

Scientists interested in molecular and materials structure with specialties in biology, chemistry, geosciences, materials science and more will converge virtually for the 71st Annual Meeting of the ACA. The theme for the 2021 meeting is “Structural Science Awakens,” which celebrates the ACA’s new tagline “The Structural Science Society.” Scientific sessions and workshops will highlight new developments in single-crystal and powder diffraction, scattering, cryo-EM, micro-electron diffraction, and advanced capabilities at national x-ray, neutron, and EM facilities.

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.

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.
