Jonathan Spreer

Jonathan Spreer is an Associate Professor in the School of Mathematics and Statistics at The University of Sydney. His research areas include Group theory and generalisations, Combinatorics, Manifolds and cell complexes, Algebraic topology, and Computational and numerical mathematics. He is based at the Carslaw Building, Room 623, and can be contacted via email at jonathan.spreer@sydney.edu.au. His personal web page provides further details about his research and publications.

Jonathan Spreer is a Lecturer in Mathematics at the University of Sydney, specializing in Combinatorial Topology, Low-dimensional Topology, Algebraic Topology, and Combinatorics. His research focuses on the algorithmic and complexity aspects of topological invariants, particularly in the context of 3-manifolds and 4-manifolds. He investigates the computational challenges of discrete Morse theory, Turaev–Viro invariants, and the treewidth of triangulated 3-manifolds. His work also explores the combinatorial properties of simplicial complexes and their applications to the classification of 3- and 4-manifolds. Spreer's contributions include the development of the simpcomp GAP package, which facilitates computational studies in algebraic topology.
