## Research

My research works are focused on the field of Several Complex Variables, a theme at the intersection between Analysis, Partial Differential Equations and Geometry. Two essential groups of questions arise in my works. The first framework concerns complex and differential geometry considerations relying on sharp analysis on manifolds such as local and global properties of solutions of nonlinear elliptic PDE systems or sharp estimates of invariant metrics. The second one is centered on analytic aspects of the theory such as boundary value problems, potential theory or extension properties.## Papers
