The Research Experience for Undergraduates program (REU) is a nationwide program funded by the NSF, where undergraduate students can spend a summer at a university doing original mathematical research. In some cases this research can even lead to a publication, and in all cases the research experience strengthens a resume for a PhD in math.
REUs typically provide students with housing and a stipend comparable to an average work-study job. NSF-funded REUs are only available to US citizens, but industry-funded research experiences like IPAM-RIPS are able to consider international applicants.Â
A list of REU programs can be found at this NSF website. Applications are usually due early in the Spring semester, but the date varies by program.
The DRP is in no way affiliated with any specific REU program. However, we encourage all our participating students to consider applying for summer research opportunities. Your DRP mentor may well have participated in an REU as an undergrad, and likely has advice about building a strong application.
