 Schedule

To be announced.

 Travel and Accommodation

The conference will take place on Cardiff University's Cathays Park campus, which is located around Cathays train station in Cardiff.

Participants will be responsible for their travel and accommodation arrangements, and are encouraged to book early to minimise costs and avoid disappointment, in particular, in view of big summertime events in Cardiff. A limited number of single ensuite rooms are available to book at Cardiff University residences during the registration via the conference registration page. 

 Funding Support

Limited funding is available to (partially) support travel and accommodation of UK-based PhD students. To apply for support, please, send an email with the subject line 'Request for UK-based PhD financial support' to 31BCC2026@cardiff.ac.uk and attach a short CV (including a list of publications) and a letter of support from your PhD supervisor. Please, also include an estimate of your costs and a statement that you do not have access to alternative funding to cover these costs. Please, notice that this support may cover your travel and accommodation at the conference only partially. 

The deadline for applications is 10 May 2026. Late applications will only be considered should funds remain unspent.

To receive support, participants must pay the registration fee and give a contributed talk at the conference.
