When considering summer research opportunities, it's advisable to engage with professors early to explore potential positions, as formal Research Experiences for Undergraduates (REUs) are not the only option available. Professors may know of other opportunities or be open to supervising independent projects, even if funding is not guaranteed. If securing a research position proves difficult, it's important to remain flexible and consider alternative paths, such as pursuing paid work or entrepreneurial ventures, to ensure financial needs are met while still focusing on academic goals.
