SPA Conferences are organised under patronage of the Bernoulli Society and can justifiably be regarded as the most important international scientific meeting on the theory and applications of stochastic processes. This series of the conferences is held every year except when the World Congress in Probability and Statistics takes place in the years divisible by 4. Due to the COVID-19 epidemic, the World Congress is postponed from 2020 into 2021, and the 42nd SPA is shifted from 2021 to 2022. The last SPA conference was held at Northwestern University, Evanston, USA in 2019.
