An REU (Research Experience for Undergraduates) letter of recommendation is a letter written by a professor, mentor, or employer that speaks to your academic abilities, research experience, and potential for success in a research-based program or position. It is often required as part of the application process for REU programs.
You should ask someone who knows you well and can speak to your academic abilities and research experience. This could be a professor, research mentor, or employer. It is important to choose someone who can provide specific examples and insights into your skills and potential.
The number of letters required may vary depending on the specific REU program or position you are applying to. It is best to check the application guidelines to see how many letters are required. In general, it is recommended to have at least 2-3 letters of recommendation.
You should request an REU letter of recommendation in person, if possible. This allows you to have a personal conversation and provide any necessary information or materials. Be sure to give your potential recommender plenty of notice and provide any relevant information, such as your CV or research proposal, to help them write a strong letter.
