2025 SIG Election

Election Home | Council | Committees | National Divisions | SIGs

Scientific Interest Groups (SIGs) are at the heart of the ACA’s vibrant scientific community—bringing together members who share common research interests, fostering collaboration, and shaping the scientific program of our annual meetings. Each SIG plays a vital role in advancing the structural sciences by promoting discussion, organizing symposia, and supporting early-career scientists. The annual SIG elections ensure that these groups continue to thrive with engaged and dedicated leadership. By voting for SIG officers, members help strengthen the ACA’s collective voice and ensure that every area of crystallography and structural science remains active, inclusive, and forward-looking.
