Gary Royden Watson Greaves

Dr. Gary Royden Watson Greaves is an Assistant Professor in the Division of Mathematical Sciences at the School of Physical and Mathematical Sciences, Nanyang Technological University (NTU), Singapore. His research focuses on algebraic graph theory, combinatorial design theory, and computational discrete mathematics. He has held academic positions including Lecturer (2016) and Senior Lecturer (2020) before becoming an Assistant Professor in 2024.

Greaves' research contributions span topics such as Neumaier graphs, equiangular lines, chromatic polynomials of signed graphs, and spectral graph theory. He has been recognized with awards including the Nanyang Education Award (College) in 2024 and a monetary award for solving parts of Wei-Hsuan Yu's conjecture in 14, 16, and 17 dimensions. His work often intersects with combinatorics, linear algebra, and computational methods.

Key research activities include collaborations on graph constructions, matrix models, and design theory. He has presented at international conferences such as the Australasian Combinatorics Conference and Combinatorics in Christchurch. His publications reflect a strong emphasis on theoretical results with applications in discrete geometry and algebraic structures.
