The application cycle for summer 2020 closed on Monday, February 3, 2020. The program, however, was cancelled on March 31, 2020.
Book mark this page for information to follow on the 2021 application cycle (to be posted by December 2020). Given the status of the pandemic, there is a possibility that the internship will be delivered virtually.

Non-Harvard applicants must first obtain an 'XID' from Harvard (no cost) in order to access the application site. To do so, please visit:  It is a very simple process, but it may take up to 24 hours before your XID is activated and accepted by the Harvard application, so please request this XID as early as possible in the application cycle.

The deadline for submitting applications for summer 2021 will be Wednesday, February 3, 2021.  There is no competitive advantage to submitting early versus late, but ABSOLUTELY NO applications or letters of recommendation will be accepted past the deadline of 5:00 p.m. (17:00 | EST) on February 3. Selection of the cohort will take place in February 2021 with decision notification to all applicants, via email, by early March 2021.  For reference, in 2020, just over 600 applications were received for the approximately 20 spots. 

Applicants who have applied in the past but were not invited may apply again.

Applicants are expected to provide, in pdf:

  • A copy of your academic transcript (unofficial version is acceptable),
  • A resume or curriculum vitae (one page, preferably)
  • Two letters of reference, containing the referee's signature, at least one from a faculty member or former teacher familiar with your academic achievements and potential (referees will receive a link so that they may directly upload the letter),
  • A personal statement of up to 750 words offering us a glimpse of who you are beyond your academic achievements, and what your aspirations may be, and how a summer in a Harvard stem cell lab will help you reach your goals. Additionally, how do the traits of resiliency, tenacity and openness to experience figure in your life? Tell us your story - use the statement to differentiate yourself from the other outstanding applicants!

To the extent possible, please make certain your pdfs are not 'secured' - particularly the unofficial transcript - that can render them unreadable by the system. If they are secured, you may have to scan the document and re-save it before submitting it. The team behind the CARAT system is working on a background solution to this problem.

Your referees will receive, via email, instructions on how to securely and confidentially submit their letters on your behalf.  They may sumit their letters before OR after you have submitted your application, but definitely must do so by the deadline of February 3, 2021. Letters of recommendation will be matched via a unique identifier to your application.

The selection process:

An Application Review Committee is assembled, comprised of postdoctoral fellows, graduate students and administrators from across the HSCI community. They meet for three sessions beginning in early February. As most applicants are stellar students with high GPAs, the Committee relies heavily on the personal statement and informative letters of recommendation from referees who truly know the applicant. Both components give the Committee a much better, more nuanced, perspective of the student and his/her prospect for success in our program. Primarily, the Committee is looking for candidates who are committed to excellence in all areas of their life; who are resilient, tenacious, and problem solvers, and; who are confident to put themselves outside their comfort zone in order to grow and develop as a student of science and a contributing member of civil society.
