The Research Experience for Undergraduates (REU) site is a program funded by the National Science Foundation that provides opportunities for undergraduate students to engage in hands-on research experiences at universities, research institutions, and laboratories. The program typically lasts for 8-10 weeks during the summer and allows students to work closely with faculty mentors on research projects in various scientific fields. REU sites aim to enhance students' understanding of the research process, develop their technical skills, and promote networking and collaboration within the scientific community. Participants often have the opportunity to present their findings at conferences and contribute to publications in scientific journals.
