img sparksMy current research is marine ecotoxicology focusing on metal concentrations along the west coast of the Cape Peninsula. The thesis looked at historical metals in the area and I also analysed metals in the water, sediment and the mussel Mytilus galloprovincialis. Part of my thesis also included antioxidant biomarker research in mussels.

I have been involved in an array of research projects such as aquaculture, physical oceanography, coastal management, marine and coastal biodiversity and currently supervising numerous MTech Oceanography students.

Previously, I was involved in jellyfish research in the region.
