For Collaborators

A reminder for investigators/collaborators: please cite the HPFS U01 grant when you are using HPFS data. 


The Health Professionals Follow-Up Study has a proud history of successful collaborations with investigators outside of the Harvard T.H. Chan School of Public Health and Harvard medical community.

We welcome new collaborations and strive to make establishing them as simple and transparent as possible, while also maximizing scientific yield.

To this effect, we have developed the following policies and guidelines for access to archived data and biospecimens, with the approval of the Health Professionals Follow-Up Study External Advisory Board and in compliance with our NIH-approved plan for data-sharing:

If you have questions after reading these guidelines, please email us at:
