Research interests

My research focuses on the analysis of partial differential equations (PDEs) modelling nonlocal interaction and/or aggregation-diffusion phenomena. The study of these PDEs arises from applications in, among others, social sciences, biology and data science. More precisely I am interested in gradient flows and their generalisation, including applications to kinetic theory and data science, optimal transport theory applied to evolutionary PDEs, systems of PDEs with nonlinear cross-diffusion and nonlocal interactions, PDEs on graphs/networks, particle approximation for (systems of ) nonlocal PDEs.
