I am an independent researcher and mathematician based in London, working in combinatorics, logic, algebraic structures, and, more recently, topology. After completing my MSci in Mathematics at Queen Mary University of London, I began working as an independent researcher.
My earlier research focused on the analysis of truth tables, particularly in multi-valued logical systems, where I studied the behaviour of bracketed formulae connected by implication. This work explored the rich combinatorial and algebraic properties that arise in such systems, especially in Kleene’s three-valued logic, which distinguishes between truth, falsity, and an indeterminate value.
A central theme of this research was the combinatorial structure of truth tables. Using recurrence relations and generating functions, I analysed these structures and showed that they can form commutative monoids, helping to clarify the algebraic foundations of a range of logical systems. This work also connected naturally with questions in theoretical computer science and discrete mathematics.
In addition, I studied divisibility properties of number sequences such as the Jacobsthal and Catalan numbers, examining how these sequences relate to logical structures and bringing together ideas from combinatorics, logic, and number theory.
My results have been presented in several papers, including preprints on arXiv, in which I developed new methods for analysing both logical and numerical systems. Alongside research, I remain deeply committed to teaching and to making advanced mathematical ideas more accessible, while fostering a broader appreciation of the subject.
More recently, I have been developing Heraclitean Dialectical Concept Space (HDCS), a mathematical framework for modelling conceptual change. This work investigates how concepts evolve, interact, and generate new concepts when existing structures break down, drawing in part on tools from topology.
