My research interests are semigroups, universal algebra and their application. My publication list gives a more detailed idea of this, however some of the repeated topics you’ll find there include:

• Finite basis problems for varieties, quasivarieties;
• Computational complexity and decidability/undecidability, especially for problems relating to finite semigroups/algebras;
• Semigroups of relations (relation algebras), functions (function semigroups), and their applications in computer science;
• The theory of natural dualities;
• Boolean topological algebras/structures.
