It is important for us to be able to help colleagues to participate in the Symposium, especially students and those for whom the costs of attendance are too great. We are pleased, therefore, to be able to offer a limited number of bursaries to those with difficulties in meeting the cost of registration, travel and accommodation.

Deadline for bursary application is the end of February 2023. The Symposium Bursary Committee will communicate to all applicants to advise whether their application has been accepted or rejected by the end of March 2023. The Early Bird rate will remain until 30 April, 2023 for both on-site and online registration.
