COMET Annual Meeting 2025

Welcome to the hybrid COMET Annual Meeting 2025!

Wednesday 4th June 2025, 12.00 – Friday 6th June 2025, 13.00

Please register for each day of the meeting separately. You will find webinar links for each day below, which will be active during talk sessions. We will monitor questions asked via the chat function during presentations. We will also provide links to recordings of these sessions after the meeting.

We have also provided links to posters that will be presented at the meeting – these pages currently display a holding image (a COMET webinar advert) but will be updated with the correct posters by the meeting start time. Please email poster presenters directly to ask them questions about their work.
