A summer research program is one of the best things you can do for a STEM path - you do real work, get mentored, and often get paid. Many are fully funded with a stipend and housing. The catch is they fill up months ahead, so timing matters as much as your résumé.
What an REU is
"REU" = Research Experiences for Undergraduates, an NSF-funded program where you join a lab for ~8-10 weeks, usually with a stipend (~$4-6k), free housing, and travel. There are parallel programs for high schoolers (e.g. RSI, SSP, university summer research) too.
Where to find them
- NSF ETAP / REU site search - the official list, filterable by field.
- Pathways to Science - a huge searchable database of summer programs and REUs.
- University "summer research" pages - most large universities run their own funded programs.
- Your own department's faculty (the direct route).
The timeline (this is the part people miss)
- Fall: make a list, note deadlines, line up recommenders.
- December - February: most deadlines land here. Apply early in the window - some review on a rolling basis.
- March - April: decisions arrive. Have backups.
Make a strong application
- Ask for recommendation letters 3-4 weeks ahead, and give recommenders your résumé and a note on what to highlight.
- Tailor your statement to that program - name labs or projects you'd want to work in.
- Lead with concrete skills and any prior project, class, or self-study, even small ones.
- Apply broadly - these are competitive; 8-15 applications is reasonable.
Remote & free options
Can't relocate or didn't get a funded spot? Remote research is real - data, computational, and literature work all happen online. The most reliable way in is to email professors directly.
What students on Reddit say
Advice that keeps coming up on r/gradadmissions, r/labrats and r/college:
- Apply to more than feels reasonable. Popular REUs get hundreds of applications for about ten spots, so students commonly apply to ten or more to land one.
- Check your own campus first. In-house summer programs (often called SURF) and your professors' labs are far less competitive than national REUs, and they count just as much.
- Beginners are the target audience. Many REUs specifically want students with little or no research experience, especially from schools with few research opportunities, so don't rule yourself out.
- Name the project you want. Statements that point to a specific lab or project at that site read as serious. Generic "I love science" essays blend together.
- National labs run on the same calendar. The Department of Energy's SULI internships and other national-lab programs pay well and share the winter deadlines, so apply alongside your REUs.
