The new EchinoClub organizers are planning a monthly series of seminars and discussions.

Catherine Schrankel

Margherita Perillo

Zak Swartz

Vanessa Barone

Sessions will be at 15:00 UTC for 90 minutes and feature one or two lab groups presenting their work leaving time for discussion and community building.

A link will be sent the day before the meeting, if you have registered for a previous meeting then you do not need to register again.

For new registrations please send an email request to and you will be added to the list.
