I'm a recently retired (in 2024) professor of Mathematics from Stellenbosch University, and am still very much into Mathematica. I use it (e.g. the command BooleanConvert in all of my articles concerned with Boolean functions and their models. Most recently I used Mathematica's FindPath in order to enumerate all subsets of vertices of a graph that induce a metric subgraph. Other research interests are finite modular lattices and finite commutative semigroups
