Who are we?

Since Crimson's founding in 2013, we've worked with over 20,000 students around the globe to help them achieve their academic and personal goals through mentorship and guidance from some of the world's brightest minds. CRI is one of our finest offerings, built for intellectually curious young students who are excited to dive deeper into in a specific academic area. 

Who are our mentors?

CRI Mentors are PhD students, postdocs, or professors with backgrounds at great universities. As a mentor with us, you'll work 1:1 or with small groups of students via video call (Zoom) and chat/email to guide them towards completing a small independent research project, such as a literature review, research prospectus, or research paper. 

If you are passionate about education and helping students discover a passion for research, we encourage you to complete the interest form below.
