National Science Foundation: Research Experiences for Undergraduates
The REU program is actually an umbrella of dozens of funded summer research opportunities for undergraduates in a wide range of scientific fields, including astronomic, atmospheric, and biological sciences, chemistry, computer engineering, earth sciences, education, engineering, math, physics, social and economic sciences, and more.
Click here for a very brief overview of the REU program. An 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.
You apply for each site individually, and programs are spread throughout the country. Check this website to search for specific programs, each of which is funded for three years. 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. Many sites have not yet updated for 2014, but still contain important information. Application deadlines vary by program site, but are generally due between January and March.
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.
