Workshop on Gap Analysis and Data Requirements to support TG and GD Development

The NanoHarmony Project hosted a global online workshop on November 3-5, with expert sessions following by a public plenary meeting.

The 3 day event delivered 14 expert sessions on 11 topics and included almost 200 experts from 25 countries across 4 continents.  The closing plenary brought together a further 150 delegates to hear initial outcomes and share discussion, ready for the next stage of development through the project.

Interested stakeholders can download the slides from each expert topic presented at the public plenary and the recordings of each session will be released shortly.  Stakeholders can also register for the follow up webinar on December 16, where outcomes from this global workshop will be presented in more detail and a roadmap of actions.
