Bettine is a Professor of Zoology at the University of Johannesburg. She is a molecular ecologist, interested in understanding the spatial patterns in species and the drivers of these. Her research often has an applied focus, where scientific findings are translated into management and conservation actions. In 2004 Bettine was introduced to the sub-Antarctic region and has since then held research grants from the South African National Antarctic Programme, with several relief voyage research visits to Marion Island. These research projects have all focussed on describing and understanding genetic spatial patterns in a variety of arthropod species as well as a keystone cushion plant species, typically using a comparative framework. Most of Bettine’s work has focussed on the sub-Antarctic Prince Edward Islands, but she has also been involved with larger multi-national studies to understand spatial patterns across the sub-Antarctic and Antarctic regions. Bettine currently serves as the South African representative to the Scientific Committee on Antarctic Research (SCAR; Biology), is involved with SCAR working-groups and is also the Vice-Chair of the ICSU SA Committee for SCAR.   Her current sub-Antarctic research programme aims to understand possible correlations between the abiotic environment and spatial genetic patterns at different spatial scales (at fine spatial scale, typically tens of meters) to the scale of Marion island. She uses molecular techniques which involve large numbers of highly variable independent markers, as well as genomic data.
