Advisors & Observers

In iMARS, we share our research and results for transparency and validation, but also to get feedback and advice from independent field experts. Their external perspectives help enrich our project and their independence from the partner organisations protects the project against any potential bias.

The following independent external experts are involved in the project to review our work and results and provide critical, strategic advice on scientific and technical aspects, on data and information security matters, as well as providing a full ethical review and vetting.
