Work experience
Currently, I am the Research Team Manager Geo-information Sciences for the Agricultural Research Council (ARC), South Africa based in Arcadia, Pretoria. In recent times (7 years ago) I worked for the University of the Witwatersrand, Rhodes University, and the Kruger National Park. I have extensive experience in managing big research teams and projects. I have extensive practical research experience on issues covering land degradation, Spatial Ecology, Population Ecology, and on aspects concerning regime shifts in relation to large mammals. Although commonly acknowledged in marine systems, terrestrial ecosystems and agricultural systems are also changing into new states dominated by different conditions than used to dominate the system earlier. I also have extensive experience in helping communities and national parks
managers to cope with the new challenges, soil erosion and land degradation issues. I sit on two advisory government groups on the use and protection of natural and agricultural resources in South Africa. Regime changes and climate change deserve more focus than is currently the case. An improved understanding of the mechanisms driving these types of changes is therefore central to my research focus and experience. My key interest is understanding the non-linear processes and
drivers to regime changes and their related effects on land degradation, soil erosion, crop yields, wild population recruitments, distribution, and abundance through modeling. My general aim is to contribute to the restoration of abiotic and biological populations and communities.
