[General description section]
Since 2004 I have been involved in amphibian research. I completed my masters in 2006 at the North-West University, South Africa. The focus of my masters was to compile a amphibian species list of the UNESCO Vredfort Dome World Heritage Site, the largest meteorite impact site in the world and to advice on the conservation of these species. For the last 3 years I have been appointed as assistant herpetologist at the Port Elizabeth Museum (Bayworld). This is one of the oldest museums in South Africa and opened the first ever Snake Park in Africa, the second in the world. It also has a long history of herpetology, with one of the largest herpetology collections in Africa.

My research focus is mainly on taxonomy, conservation and ecology of African amphibians and reptiles. One of the projects I’m involved in is the conservation of the Hewitt’s Ghost Frog (Heleophryne hewitti, EDGE #15). Since 2008 is I started monitoring the tadpoles and marked them with visual implanted elastomer (V.I.E) markers to understand the movement, population size and breeding cycles of these species. Furthermore, we want to look at the ecology of these tadpoles. What do they eat? What is there throphic status? But most important is to combine this information into a conservation management plan that can be implemented by the local landowners.
