Graduate students engaged in academic travel may apply for funding through the Student Government Association. As long as there is matching funding through other departments, the SGA may offer up to $500 for an individual applicant and up to $1,500 for groups of 3 or more applying together. See details in the Activity and Service Fee Manual.
The McNair Scholar website lists various agencies and organizations, both private and governmental, that offer financial support for graduate study. Some of the support opportunities are "full-ride" research fellowships, others are limited-duration research internships, still others provide a set amount of funds for a specific scholarly work. See the McNair Scholar website: http://mcnairscholars.com/funding/ for each opportunity.
