National Divisions
As the North American Regional Affiliate of the International Union of Crystallography (IUCr), the American Crystallographic Association (ACA) represents structural scientists from across the Americas within the global crystallographic community. To ensure that national perspectives are reflected in ACA governance and international engagement, the Association maintains National Divisions, each with its own leadership structure and an elected representative serving on the ACA Council.
