​

  • STUOD SPDEs Seminar: This is an internal seminar I initiated and organised weekly within the STUOD  research  group between 2021-2022. The aim of the seminar has been to provide a framework for discussing all STUOD models from an SPDEs perspective.

​

  • Invited session in the 2022 IMS Annual Meeting in Probability and Statistics, London, 27-30 June 2022.

    Title: Stochastic Models in Fluid Dynamics

  Purpose of the session: The turbulent behaviour of the multi-scale physical processes which are modelled in fluid dynamics has intrigued generations of mathematicians. More accurate representations of such processes involving stochastic perturbations has been the subject of intensive research in recent years. As a consequence, new systems of stochastic partial differential equations (SPDEs) have been introduced by combining classical fluid dynamics models with different classes of noise: additive, multiplicative, transport, rough path noise. The analyticalproperties of these SPDEs provide a rigorous probabilistic description of the underlying fluidmodel and their numerical inference is essential for subsequent applications. The purpose of this session is to present recent analytical and numerical results on this topic, while introducing the audience to modern stochastic analysis tools which enable an enhanced understanding of random phenomena.

​

  • Co-organiser for the  GAMM Minisymposium for Young Researchers in Data Assimilation, Aachen, Germany, 15-19 August 2022.
