报告人简介：Paolo Piccione, Graduated in Mathematics from the University of Rome La Sapienza (Italy, 1987), and Ph.D. in Mathematics from Pennsylvania State University (USA, 1994), holds a Livre Docência at the University of São Paulo (1998). Served for three consecutive terms (2017-2023) as the President of the Brazilian Mathematical Society, and currently holding the position of Full Professor (MS-6) at the University of São Paulo. A full member of the Brazilian Academy of Sciences since May 2012, and a member of the Executive Committee of the International Mathematical Union (IMU) for a second term (2023-2025), as well as a member of the Special Committee on Work Regimes (CERT) at USP, and part of the Coordination of Area - Mathematics and Statistics at Fapesp. Admitted to the National Order of Scientific Merit in the rank of Commander, in the field of Mathematical Sciences, in 2018.
    He has served as a member of the Advisory Board in Mathematics for the Brazilian Ministry Of Science and Technology, President of the Research Committee of  the Institute of Mathematics and Statistics of the University of Sao Paulo (USP), member of the Research Council of USP, and member of the Sectoral Assessment Committee (CAS) for Mathematics and Statistics at the University of São Paulo. His mathematical specialty is Differential Geometry, primarily engaged in the following topics: Calculus of Variations and Geometric Variational Problems, Bifurcation Theory, Global Riemannian and Lorentzian Geometry, Morse Theory, Symplectic Geometry, and Hamiltonian Systems. He coordinates the Fapesp Thematic Project Algebraic, Topological, and Analytical Techniques in Differential Geometry and Geometric Analysis. Since March 2017, he has held the status of Researcher 1A of the Brazilian National Committee for Research.
    His contributions to the Brazilian Mathematical Society (SBM) encompass participation in the Evaluation Committee for the IMPA-SBM Journalism Prize, coordination of the SBM Prize Jury, and involvement in the editorial committees of the journals: Revista Matemática Universitária (Chief Editor), Matemática Contemporânea (Associate Editor), and the SBM Newsletter.
