Simone Naldi

Simone Naldi is a Lecturer (Maître de conférences) in Applied Mathematics at the University of Limoges, France, since 2017. His research focuses on algebraic geometry, optimization, and symbolic computation, with applications to semidefinite programming and linear matrix inequalities. He holds a PhD from CNRS-LAAS in Toulouse and has held postdoctoral positions at the University of Dortmund and the Fields Institute in Toronto. His work includes developing algorithms for solving polynomial systems and creating the SPECTRA library for exact LMI solutions. He has collaborated on projects involving geometric configurations, hyperbolic curves, and infeasibility certificates for optimization problems.

Key research areas include semidefinite programming, algebraic certificates for moment problems, and computational tools for polynomial equations. He actively contributes to conferences like Structured Matrix Days and has been supported by institutions like the Simons Foundation. His recent work addresses degenerate systems and geometric configurations of spheres in tetrahedrons, reflecting his interdisciplinary approach combining pure mathematics with algorithmic development.
