2025 sees the 18th year of the Colloquia in Combinatorics. Like every year, the 2025 Colloquia feature twelve talks covering a wide range of topics of interest to those working in combinatorics or related fields.

Registration for the 2025 Colloquia is now available. Standard registration is intended for participants with access to a grant or institutional travel support, free registration for all other participants. Please register before the start of the event.

The 2025 Colloquia are organised by Felix Fischer (QMUL), Shoham Letzter (UCL), Viresh Patel (QMUL), Alexey Pokrovskiy (UCL), and John Talbot (UCL).
