Juan Jose Nuño Ballesteros

Juan José Nuño Ballesteros is a Professor in the Department of Mathematics at the Faculty of Mathematics, Universitat de València, Spain. He is a leading researcher in singularity theory, with a focus on the geometry and topology of singular spaces and mappings. His work bridges differential geometry, topology, and complex analysis, particularly in the study of map germs, determinantal singularities, and equisingularity.

He obtained his PhD from the Universitat de València in 1991 under the supervision of Dr. Angel Montesinos Amilibia, with a thesis on global generic properties of curves in R³. He is a core member of the research group GEOSING (Singularities, Generic Geometry and Applications), contributing significantly to the understanding of singularities in low-dimensional spaces.

His research interests include:

• Singularity Theory
• Differential Geometry
• Topology of Manifolds
• Several Complex Variables
• Algebraic Geometry
• Global Analysis

His most recent publications (2020–2024) continue to explore foundational problems in singularity theory, including the Mond conjecture, equisingularity of families, and the topology of Milnor fibrations. His work often involves deep interactions with collaborators from Brazil, Japan, and other European institutions, reflecting a strong international research network.

Nuño Ballesteros has authored over 100 publications, including a major book with David Mond. His research has been widely cited, indicating significant impact in the mathematical community.

He has supervised several PhD students, including João Nivaldo Tomazella, Bruna Oréfice-Okamoto, and Juan Antonio Moya-Pérez, contributing to the training of the next generation of mathematicians in singularity theory.

There are no indications of retirement or emeritus status; he remains an active researcher, with recent publications confirming his ongoing scholarly contributions.
