Presentation

My research interests mainly focus on the stochastic modelling and analysis of geophysical flows. This includes the development of large-scale stochastic dynamical models, the identification of reduced-order dynamical models, the creation of measurement techniques dedicated to specific flows, and the design of data assimilation frameworks. These research topics lie at the intersection of various disciplines, including geophysical sciences, fluid mechanics, computational sciences and applied mathematics.
