Research interests

My research interests are semigroups, universal algebra and their application.  A sample of specific topics of interest 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. 

An up-to-date publication list can be found here.  My official publication list is not so often updated, so is usually out of date.
