Your supervisor must be included as the main applicant on the application and they must review and submit the application. They must also have access to the TRE so that they can provide practical support and oversight of your analyses.
MSc student you can submit an EoI if your project timeline permits (note, it takes at least 12 weeks from submission of an EoI to access to the TRE). The same requirements that apply to PhD students also apply to MSc students.

1UK LLC is working with its public contributors to develop a context-specific public good definition which will replace our use of the NDG definition - we will update this page in due course.
3. Data requirements
Please note that UK LLC may not hold all data collected by each LPS. Before proceeding with your EoI, check availability of data using the links below:
