Florian Galliot

Florian Galliot is an Associate Professor in Mathematics at Aix-Marseille University, conducting research with the GDAC team at the Institut de Mathématiques de Marseille (I2M) and teaching in the Computer Science department of IUT d'Aix-Marseille. Previously, he was a temporary teaching and research assistant at Université de Bordeaux and completed his PhD in discrete mathematics at Institut Fourier under Sylvain Gravier and Isabelle Sivignon, defended on July 3, 2023.

His primary research interests include:

• Positional Games and Combinatorial Games
• Structural Graph Theory
• Hypergraphs and their properties
• Reconstruction and Reconfiguration Problems in graphs

Galliot's research focuses on positional games, a family of combinatorial games played on hypergraphs (including games like tic-tac-toe, Hex, and Sim). His work bridges theoretical mathematics with practical applications, examining computational complexity, game strategies, and structural properties of graphs and hypergraphs. He has made significant contributions to understanding the Maker-Breaker game, Avoider-Enforcer games, and poset positional games, with several publications in top journals and conferences.

His recent publications (2023-2025) demonstrate a consistent research trajectory in positional games on hypergraphs, with a particular focus on computational complexity and structural properties. His work shows increasing sophistication in analyzing games on hypergraphs of various ranks, with several results establishing polynomial-time solutions or complexity classifications.

Galliot is actively involved in mathematics popularization:

• Member of 'Maths à Modeler' federative structure
• Participant in Science Festival, Culture and Mathematical Games Fair, Remue-Méninges Festival
• Previously supervised the mathematics club 'Les maths autrement' in Grenoble (2019-2022)

His teaching portfolio spans fundamental mathematical tools, graph theory, cryptography, automata and languages, and algorithm implementation across multiple institutions including Aix-Marseille University, Université de Bordeaux, and Grenoble Alpes University.
