Becoming a TIES Member

An ISI membership is NOT required in order to be a TIES member. TIES membership fees information is available here.

If you were not a TIES member in this calendar year, please click here to join TIES for a membership for the upcoming calendar year. Note that this is a new portal as of February 2025.

All members of TIES with a current calendar year membership should have already received an invoice directly from the ISI with an invitation to renew, via the new Oodo web portal.

For more information on TIES memberships, please contact the Society Secretary:
