We are pleased to announce dates for the 2021 BIEN Congress. To keep a degree of flexibility at this stage, the local organising committee in Glasgow has opted for two possibilities: either 18-21 August or 19-22 August. Since the situation with Covid restrictions is still fluid, and unknowable so far in advance, they are also planning for three possible scenarios: a virtual congress, a congress both physical and virtual, and a physical congress with virtual aspects. A call for papers will come out soon.
