The international honor society of science and engineering, Sigma Xi (Xi is pronounced with a "Z" sound--Sigma "Zi"--as in "xylophone")
was founded in 1886 to honor excellence in scientific investigation and encourage a sense of companionship and cooperation among researchers in all fields of science and engineering. The Greek letters "sigma" and "xi" form the acronym of the Society's motto, "Spoudon Xynones," which translates as "Companions in Zealous Research."
Today, Sigma Xi has nearly 60,000 members who were elected to membership based on their research potential or achievements. Sigma Xi has a distinguished history of more than a century of service to science and society. Its programmatic efforts focus primarily on science and engineering education, ethics in research, public understanding of science, international science networking, and the overall health of the research enterprise.

Sigma Xi is a non-profit membership society of scientists and engineers whose research spans the spectrum of science and technology. 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 which research can thrive. To date, more than 200 Sigma Xi Members have won the Nobel Prize.

The Society endeavors to encourage support of original work across the spectrum of science and technology and to promote an appreciation within society at large for the role research has played in human progress. To that end, Sigma Xi publishes the award-winning American Scientist magazine, awards hundreds of grants annually to promising student researchers, and sponsors a variety of programs that serve science and society. Primary programmatic interests include research ethics, science and engineering education, the public understanding of science, international research networking and the overall health of the research enterprise. At the new Sigma Xi Center in Research Triangle Park, North Carolina, the Society is enhancing and expanding programs in support of its members, chapters and the research community.

The Sigma Xi Grants-in-Aid of Research (GIAR) program has been providing undergraduate and graduate students with valuable educational experiences for more than 80 years. By encouraging close working relationships between students and faculty, the program promotes scientific excellence and achievement through hands-on learning.

The program awards grants of up to $1,000 to students from all areas of the sciences and engineering. Designated funds from the National Academy of Sciences allow for grants of up to $5,000 for astronomy research and $2,500 for vision related research. Students use the funding to pay for travel expenses to and from a research site, or for purchase of non-standard laboratory equipment necessary to complete a specific research project.

While membership in Sigma Xi is not a requirement for applying for funding from the Grants-in-Aid of Research program, approximately 75% of funds are restricted for use by dues-paying student members of Sigma Xi, or students whose project advisor is a dues paying member of Sigma Xi. Students from any country are eligible to receive funding

Application Deadlines: March 15 and October 15, annually.
