The National Science Foundation Graduate Research Fellowship Program (NSF-GRFP) is an annual grant awarded by the National Science Foundation to approximately 2,000 doctoral-level students in the natural, social, and engineering sciences at US institutions. The fellowship provides an honorarium of $12,000 to be placed towards the cost of tuition and fees at the university the fellow attends; it also awards the student directly with an annual $34,000 stipend for three years. Each recipient could previously apply for a one time only travel award for $1,000. This travel award was previously for international research activities or presenting at an international scientific conference. However, in 2010, this opportunity was converted to the Nordic Research Opportunity, which is intended to facilitate collaborations between U.S. graduate fellows and scholars at Finnish, Swedish, Danish, and Norwegian research institutions.
