Diagrams will use two online platforms for the virtual event: Zoom and Wonder. The presentations will be given over Zoom. Presenters are expected to attend the indicated networking sessions to discuss their contributions with delegates in an informal setting. These networking sessions will take place in Wonder. Delegates can access the conference’s Wonder space at any time during the conference to meet with other delegates. Links to both platforms will be provided to delegates.
To access the sessions, click on the links in the program below and use the passcode that you have been sent, via EasyChair. Only registered delegates will have the passcode.
For URGENT questions that arising during sessions please email diagramsconference@cl.cam.ac.uk. This address will be monitored during the conference sessions and you should receive a reply fairly quickly, depending on demand. This email address is not for general enquires about the conference.
