Introducing ACA: The Structural Science Society

After over a year of development we are excited to launch the new ACA logo incorporating "The Structural Science Society".  The ACA has always been a home for structural scientists and as the science develops and grows so are we.  ACA Vice President Cora Lind-Kovacs summed up the change perfectly:

"As we continue to push for new frontiers, combining data obtained by such methods with traditional crystallographic diffraction or other scattering techniques holds tremendous potential, and the addition of “The Structural Science Society” shows that the ACA is committed to providing a place that brings together all scientists that are pursuing atomic level structural analysis."

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.

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.

Education & Outreach
