2024 SIG Officers & Governing Information/Documentation
Scientific Interest Groups (SIGs) are a vital part of the ACA. There are fourteen SIGs that each represent a particular discipline within the field of crystallography, allowing members to focus on their area of specialty while retaining access to interaction with the entire range of crystallographic techniques and applications. Any member may join however many SIGs they wish. There are no additional fees association with SIG membership.
SIGs exist to give members the opportunity to focus on specialty areas while remaining connected to the entire scope of crystallographic applications. Joining a SIG means finding individuals within the larger network who have common scientific goals, challenges and interests.
Scientific Interest Groups represent the social networking within the ACA designed to:
-
Encourage stimulating scientific exchange
-
Promote collaboration within specific areas of focus throughout the crystallographic community
-
Provide opportunities to involve new, current and retired members in the organization
SIGs are responsible for defining the program at annual meetings. Each SIG is charges with organizing at least one half-day session every two years. This is a great opportunity for members to get involved in the ACA at a grass roots level and have a direct impact upon the annual meeting.
By joining the ACA you will have the ability to join as many SIG's as you wish and start to connect with members with similar backgrounds and goals. When you join a the ACA and SIG's you broaden your network of peers and colleagues and get to enter a unique community of scientists that share your interests and areas of focus.

Best Practices for Data Analysis & Archiving SIG
The BPDAA SIG was created to join the major effort in the international community to standardize best practices in data analysis and archival and further, to improve community involvement in these best practices.

Canadian Division
As the North American Regional Affiliate of the International Union of Crystallography (IUCr), the ACA plays a significant role in promoting the applications and techniques of crystallography beyond U.S. borders. The ACA represents all of North and South America to the global scientific community. Canada is the largest single country outside the United States to contribute to the goals and purposed of the ACA. The Canadian Division exists therefore to promote the interests of Canadian members and to provide for an elected official to represent these interest on the ACA Council.

Fiber SIG
The Fiber SIG represents the interests of fiber diffraction specialists and application of fiber diffraction in interdisciplinary studies. This is a diverse group that employs the use of X-rays, neutrons and elections in diffraction experiments in addition to modern computational molecular modeling approaches.
This SIG meets every other year, with the next meeting scheduled for 2024. This SIG also only participates in elections every other year. The next year to include candidates for this SIG will be the election of 2024 with officers to being their position on January 1, 2025.
