Consider gaining valuable research experiences this summer by participating in National Science Foundation’s Research Experience for Undergraduates (REU) program. Here is one example of the type of opportunities available: (http://www.montana.edu/mbi/reu/). You can search for other great REU opportunities on NSF’s website (https://www.nsf.gov/crssprgm/reu/reu_search.jsp). Please note that applications are accepted through individual REU websites and not on the NSF website.
