Marcello Ponsiglione is a Full Professor at the Department of Mathematics, University of Rome La Sapienza. His research focuses on calculus of variations, geometric flows, and materials science with applications to dislocation mechanics, fractional dynamics, and nonlinear elasticity. He has contributed significantly to Γ-convergence analysis, nonlocal geometric flows, and the mathematical modeling of crystalline structures. His work frequently bridges discrete-to-continuum transitions, analyzing energy minimization problems in materials science contexts. Key areas of research include the dynamics of screened particles, fractional perimeters, and the study of edge dislocations in elastic materials. He has explored topics like area-preserving mean curvature flows, nonlocal geometric evolutions, and stability of supercritical fractional curvatures. His collaborations span international teams, yielding over 50 publications. Ponsiglione has organized workshops on calculus of variations and PDEs in geometric analysis. His research integrates analytical techniques from functional analysis, partial differential equations, and geometric measure theory to address challenges in applied mathematics and material physics.
