The Society for Industrial and Applied Mathematics (SIAM) is an international community of over 13,000 individual members. Almost 500 academic, manufacturing, research and development, service and consulting organizations, government, and military organizations worldwide are institutional members.

SIAM fosters the development of applied mathematical and computational methodologies needed in these various application areas. Applied mathematics in partnership with computational science is essential in solving many real-world problems. Through publications, research, and community, the mission of SIAM is to build cooperation between mathematics and the worlds of science and technology.

SIAM was incorporated in 1952 as a nonprofit organization to convey useful mathematical knowledge to other professionals who could implement mathematical theory for practical, industrial, or scientific use. Since then, SIAM’s goals have remained the same:

• To advance the application of mathematics and computational science to engineering, industry, science, and society;
• To promote research that will lead to effective new mathematical and computational methods and techniques for science, engineering, industry, and society;
• To provide media for the exchange of information and ideas among mathematicians, engineers, and scientists.

SIAM is headquartered in Philadelphia, Pennsylvania, staffed by more than 60 full- and part-time employees.
