For researchers

GUTS has a proud history of successful collaborations with investigators around the world, and we always welcome new collaborators.

External investigators interested in using GUTS data are invited to fill out a form describing their proposal. The vast majority of requests are approved.

Internal investigators from Brigham and Women’s Hospital, Harvard Medical School, and Harvard T.H. Chan School of Public Health should follow Channing Division of Network Medicine guidelines on presenting analysis proposals  (login required) for feedback and approval by GUTS leadership.

Use of biologic samples

The BWH/Harvard Cohorts Biorepository houses more than 3.2 million biological specimens from participants in GUTS and other cohorts. The Biorepository welcomes new collaborations.
