NSF Research Experiences for Undergraduates (REUs)

NSF funds a large number of research opportunities for undergraduate students through its REU Sites program.  Each REU Site consists of a group of ten or so undergraduates who work in the research programs of the host institution. Each student is associated with a specific research project, where he/she works closely with the faculty and other researchers. Students are granted stipends and, in many cases, assistance with housing and travel. Undergraduate students supported with NSF funds must be citizens or permanent residents of the United States or its possessions. An REU Site may be at either a US or foreign location.

By using the web page, Search for an REU Site, you may examine opportunities in the subject areas supported by various NSF units. Also, you may search by keywords to identify sites in particular research areas or with certain features, such as a particular location.

Students must contact the individual sites for information and application materials. NSF does not have application materials and does not select student participants. A contact person and contact information is listed for each site.


The eligibility requirements varies by REU site.  Typically, rising sophomores, juniors, and seniors are eligible to participate in these summer research programs.

Period of Study

The length of research experience varies by REU site.  Typically they consist of 10-12 weeks during the summer, culminating in a research showcase celebration at the end of the summer.


The award varies by REU site.  Typically, students receive a generous stipend (~$6000).  Housing is also often provided as is transportation to and from the REU location.


Apply to each REU site directly.  REU sites may be found through the NSF's search engine, Search for an REU Site.


Deadlines vary by REU site.  Typically, most applications are due before March 1st.
