I am a postdoctoral researcher at the Computer Science Research Institute of Lens (CRIL, CNRS & Univ Artois), France. My primary research focuses on the representation of natural language and reasoning. Specifically, I explore (from both cognitive and non-cognitive perspectives) the extent to which diagrammatic representations can support reasoning. 

During my PhD (defended in 2022) at the Institut Jean Nicod in Paris, under Paul Egré's supervision, I investigated the nature of the mental representations constructed to reason on spatial problems described linguistically ("A is to the left B", "Brussels is in Belgium", ...) and  I designed  a computational framework that models these cognitive processes using the non-monotonic language Answer Set Programming (ASP) and the Declarative Spatial Reasoning framework. In my first postdoc, together with Martin Dieguez, I developed a semantics for ASP that integrates constraints from external theories and temporal logics such as Linear Temporal Logic. Currently,  in my postdoc with Zied Bouraoui, I am working in the field of neurosymbolic AI, aiming to enhance the reasoning capabilities of large language models.
