Shuhei TSUJIE

Shuhei TSUJIE is an Associate Professor in the Department of Mathematics at Hokkaido University of Education, Asahikawa Campus, Japan. His research focuses on Algebraic Combinatorics, Hyperplane Arrangements, Graph Theory, Discrete Geometry, and Invariants of Finite Reflection Groups. He is actively engaged in studying the combinatorial and algebraic properties of hyperplane arrangements, including freeness criteria, characteristic quasi-polynomials, and their connections to graphs and posets.

TSUJIE's work has been published in leading journals such as Algebraic Combinatorics, European Journal of Combinatorics, and Discrete Mathematics. His recent research explores topics like MAT-labeled graphs, vertex-weighted digraphs, and extended Catalan/Shi arrangements. His contributions often bridge discrete mathematics with algebraic structures, emphasizing the interplay between combinatorial configurations and geometric/topological properties.

He has presented at numerous workshops, including the 'Hyperplane Arrangements 2023' and 'Asahikawa Discrete Mathematics Seminar'. Despite his prolific output, no scientific awards are explicitly mentioned in the provided text. His research is supported by collaborations with international colleagues, reflecting his global academic engagement.
