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. 

Investigators interested in collaborations are invited to fill out a simple form that asks about the details of the collaboration. Every two weeks, new collaboration requests are reviewed based on the scientific merit and feasibility; the vast majority of requests are approved.

For more information about the archived data collected from the Nurses' Health Studies, please visit the Nurses' Health Studies questionnaires archive.
