There is a lot of variation in how circadian data, and associated mental health data, are collected, described and processed. However, for data to be shareable, it needs to be in a common format.

We aim to contribute standardised approaches to maximise the impact of data collected across the research community. To do this, we will:

• work with the research community to co-produce approaches to develop common standards

• use FAIR data principles to guide this production (Findability, Accessibility, Interoperability and Reusability)

• work closely with our LEAP group to address any ethical concerns that may arise during this process

• share our approaches with the wider research community
