Research Description

My primary research interest is in Near Vector Spaces, with the aim of developing a theory which parallels that of vector spaces.

As a secondary research interest, in collaboration with Professor Carl Maxson (Texas A & M University, USA), we investigate algebras of functions associated with a given algebraic structure. The question is when the set of endomorphisms of the universal algebra A will be a maximal structure in the set of all maps of A?

The investigation begin with finite monoids and our goal is to extend this to an investigation of endomorphism algebras of finite universal algebras.

Research Rating

In November 2020 I was awarded a C2 rating from the South African National Research Foundation (NRF).

Professional Societies

I am a member of the South African Mathematical Society and the American Mathematical Society. As of January 2020 I am the secretary of the South African Mathematical Society.

Since November 2014 I am a reviewer for the American Mathematical society. I have refereed papers for Journal of Algebra, Results in Mathematics, UFA Mathematical Journal, Discussiones Mathematicae, General Algebra and Applications.

Promoting Women in Mathematics

I am the founder and convenor of a committee who organises the African Women in Mathematics (AWiM) Conferences and Virtual Seminars at Stellenbosch University since 2019. As part of our virtual seminars we have hosted Eugenic Chang, Federico Ardila and Nalini Joshi.
