Peer Concentration Advisors

Peer Concentration Advisors (PCAs) serve as peer advisors for current CS concentrators and pre-concentrators, providing a valuable perspective and helping students to discover additional resources and opportunities. Students can reach out to meet with PCAs with similar academic, career, or extracurricular interests.

For more information, including if you would like to find and meet with a PCA that would be a good match for your interests or concerns, or if you are interested in being a PCA, please reach out to the PCA Co-Captains, Matthew Nazari and Omar Shareef, through the email address cs-pca@seas.harvard.edu.
