The EnviBayes–INLA Workshop 2027 is the first joint meeting between the EnviBayes and INLA workshop series, bringing together researchers developing Bayesian methods for environmental, ecological, spatial and spatio-temporal statistics. The programme will feature keynote lectures, contributed talks, poster sessions, and hands-on tutorials, covering a broad range of topics including INLA, spatial modelling, extreme value analysis, climate and weather, ecology, epidemiology, and environmental applications. The workshop builds on the success of previous EnviBayes workshops (2023, 2025) and the INLA: Past, Present and Future workshop, creating a unique opportunity for collaboration between these two vibrant research communities.
