The laboratory for Algebraic Geometry and Applications to Information Theory (GAATI in French) is a mathematics research unit accredited since 2004 by the French Ministry of Higher Education and Research (EA 3893). It is the only research group in mathematics in French Polynesia.

The efforts of the GAATI laboratory aim to increase the efficiency and security of information transport and control systems through the development of new computational and cryptographic techniques. To this extent, the laboratory develops and exploits mathematical methods based on algebraic geometry and number theory.
