I am interested in the nature of genetic variation – how it arises and spreads within and between species. I enjoy investigating these things in natural populations, and trying to think of creative ways to summarise and visualise these phenomena. I have led a research group in Edinburgh since 2019.  I was at the University of Cambridge for my PhD and stayed there for my first research fellowship, where I worked on population genomics and speciation in Heliconius butterflies. Before that I worked on fungal genetics during my masters at the University of Pretoria, in my original home country of South Africa.
