Sigma Xi: The Scientific Research Society (ΣΞ) is a non-profit honor society which was founded in 1886 at Cornell University by a junior faculty member and a handful of graduate students. Members elect others on the basis of their research achievements or potential. Despite the name, Sigma Xi is neither a fraternity nor a sorority, and today is open to all qualified individuals who are interested in science and engineering.
Today the Society comprises nearly 100,000 scientists and engineers who were elected to membership based on their research achievements and potential. More than 500 Sigma Xi chapters in North America and around the world provide a supportive environment for interdisciplinary research at colleges and universities, industry research centers, and government laboratories. In addition to publishing the award-winning American Scientist magazine, Sigma Xi provides grants  annually to promising young researchers and sponsors a variety of programs supporting ethics in research, science and engineering education, the public understanding of science, international research cooperation and the overall health of the research enterprise. The Society is based in Research Triangle Park, North Carolina.
Culture: The Society is a diverse chapter-based organization dedicated to the advancement of science and engineering through outstanding programs and services delivered in a collegial and supportive environment.
Mission: To enhance the health of the research enterprise, foster integrity in science and engineering, and promote the public's understanding of science for the purpose of improving the human condition.
Vision: To be the global honor society of science and engineering.
