For researchers

The Nurses' Health Studies have a proud history of successful collaborations with investigators outside of the Brigham and Women's Hospital, Harvard Medical School, and Harvard T.H. Chan School of Public Health 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 Nurses' Health Studies 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: nhsaccess@channing.harvard.edu
