José M. Mazón is an emertius professor of mathematical analysis at the University of Valencia. He is a specialist in nonlinear partial differential equations, a field in which he has published more than 160 research articles in prestigious journals. His research topics include singular and degenerate nonlinear PDEs, image processing equations, flux limited diffusion equations, mass transport theory and nonlocal equations. Some of his results have been published in six monographs: Parabolic Quasilinear Equations Minimizing Linear Growth Functional (Birkhäuser, winner of the 2023 Ferran Sunyer i Balaguer Prize), Nonlocal Diffusion Problems (American Mathematical Society, 2010), Nonlocal Perimeter, Curvature and Minimal Surfaces (Birkhäuser, 2019), Variational and Diffusion Problems in Random Walk Spaces (Birkhäuser, 2023), Functions of Least Gradient (Birkhäuser, 2024) and Weak Solutions to Gradient Flows in Metric Measure Spaces (Cambridge University Press, 2026).
