REUs are specialized programs that offer undergraduate students the opportunity to participate in research projects under the supervision of faculty mentors. These programs are usually hosted by universities and research institutions during the summer months. They provide students with hands-on experience in their field of study and exposure to research methodologies. Furthermore, REU programs are designed to prepare students for graduate studies or careers in research and help students explore potential career paths in academia or industry.
