About

My name is Guy Sutton. I am a Research Entomologist at the Center for Biological Control at Rhodes University (South Africa). My research primarily involves finding and developing insect biological control agents for managing invasive alien plants, with a particular focus on managing invasive African grasses that have become invasive globally.

Moreover, I passionate about developing quantitative methods and software for answering ecological questions, bridging the spheres of statistics, software development, coding and ecology.

I am currently appointed as an Associate Editor for the international peer-reviewed scientific journal Ecology and Evolution
