Jaco is an Associate Professor of Botany at Stellenbosch University in South Africa. His background is in population genetics and phylogeography, and he applies these approaches to better understand the microevolutionary dynamics of plants, and particularly introduced, non-native species. Jaco’s research also aims to disentangle the patterns and pathways of historical extreme long-distance dispersal to explain peculiar plant distributions. In addition, he is interested in plant-microbial interactions (legumes and nitrogen-fixing rhizobia) and their role in facilitating establishment of non-native legumes, and how these impact on native plant-mutualist ecological networks.
