Trained as a physicist, I am interested in modelling arid ecosystems, and in particular in understanding the links between spatial vegetation patterns and the resilience properties of these ecosystems. The aim of my thesis is to develop theoretical tools to analyse the full diversity of spatial organisations observed through remote sensing, ranging from scale-invariant structures to periodic patterns. To this end, we focus especially on the role of spatial scales and how they can be integrated into the study of arid ecosystems. Our approach is interdisciplinary, combining numerical modelling, mathematical development, satellite data analysis, and the mobilisation of existing ecological knowledge.
