Ban Pin Tan

Dr. Ban Pin Tan is a Mathematics Lecturer at the National University of Singapore (NUS), holding a PhD from NUS awarded in 1997. His research focuses on graph theory and digraph properties, particularly in kings in multipartite digraphs, eccentric digraphs, Roman domination, bondage numbers, and optimal orientations. He has contributed to over 8 peer-reviewed publications since 1995, addressing structural properties of tournaments and multipartite graphs. His work includes foundational studies on dominance hierarchies, 3/4-kings enumeration, and digraph orientation optimizations.

Dr. Tan emphasizes teaching methodologies that foster deep conceptual understanding through systematic lecture notes, 'Pause and Think' sessions, and problem-solving exercises. He believes in inspiring students to apply mathematical principles to real-world challenges, aligning with Singapore's knowledge-based economy goals. His pedagogical approach combines rigorous problem sets with frequent quizzes to enhance critical thinking and engagement.

His long-term research program includes: (1) studying kings-of-kings in semicomplete multipartite digraphs, (2) analyzing eccentric digraphs of various graph classes, (3) determining optimal orientations for graph families, (4) evaluating Roman domination and bondage numbers, and (5) exploring magic graph properties. Current investigations focus on eccentric digraphs, Roman domination extensions to digraphs, and magic graph characteristics.
