The 2026 iSTRUM Community Workshop is complete!
Thank you to all attendees for making it an enjoyable, thought provoking week. If you attended but have not completed the post-meeting survey, please check your email or contact the organizers! Your feedback is immensely helpful.

Workshop Resources#
A number of resources are available for both attendees and the wider community:
Talk slides, meeting materials#
The google drive used during the meeting remains publicly accessible in a read-only view: iSTRUM 2026 Community Workshop Google Drive
it includes:
- an archive of the full agenda and participants ( link)
- slides from talks contributed by speakers ( link)
The padlet discussion board has been frozen but can still be viewed at this link. Additionally, a PDF archive of the discussion board is available at this link.
