AbstractThis session features the CERN groups that run in various locations around the world. Organisers from CERN groups will make brief presentations about the activities of the group (and how this might have changed over time). Those who attend CERN groups will be invited to share their reflections, including some insights into the role CERN groups play in their research and practice. This will be followed by discussion of the challenges facing CERN groups (especially the challenge of finding time for this activity in busy lives). Overall, the session is an opportunity for those involved or interested in CERN groups to connect with each other and share what they are doing.Current CERN groups are:• CERN ABC/DE (Arts-based Community/Diverse Economies)• CERN América Latina• CERN Aotearoa New Zealand• CERN Asia• CERN Europe• CERN North America• CERN SydneyCERN presenters at this session: Heather McLean and Molly Mullen (CERN ABC/DE); Pryor Placino and Ann Hill (CERN Asia); Stephen Healy and Bhavya Chitranshi (CERN Sydney); Jenny Cameron (CERN Aotearoa New Zealand); and Christian Anderson (CEI).
