My research interests lie in studying the cycling of trace elements in water bodies and understanding chemical and biological processes influencing their fate, transport and transformation. While my previous research focused on the interaction of mercury with reduced sulfur species in sediments, my current focus is on arsenic and other trace elements in the Okavango Delta. Specifically, I am interested in:
Results from my research can be used to carry out human health and environmental risk assessments and craft better management plans for aquatic systems.
