Gazel has been designed as a "human epidemiological laboratory", open to the scientific community, allowing epidemiological projects on very diverse themes, with high quality data and reduced costs.

Any research team can submit a scientific and technical application to conduct studies based on Gazel data.

Each acceptal project can use some of the Gazel data and its logistic support. In return, after an exclusive agreed-upon use period, project managers agree to allow the scientific community use of their project-specific data.
