About this Website
This website helps students apply for the National Science Foundation (NSF) Research Experiences for Undergraduates (REU) Sites and the International Research Experiences for Students (IRES) Sites programs. However, not all Sites participate in this online system. To view a list of Sites using this system, please go to the Sites tab.
This website also enables principal investigators at Sites, NSF officers, and other authorized users to enter or access data.
