With a professional background in marine systems ecology, I have been specializing on an ecosystem approach to fisheries management (EAF) since the late 1980s. My research emphasis has been on exploited marine systems experiencing pronounced environmental signals, and in developing societies. My research interests include the development of ecosystem indicators for fisheries management, multivariate data analysis and systems modelling, as well as mediated modelling. I have senior experience in developing scientific advice for management of human activities in the ocean.
Holding the South African Research Chair in Marine Ecology and Fisheries, my current research focuses on developing methodology for multiple-criteria decision support for human activities in marine social-ecological systems under global change, notably in the Benguela Current Large Marine Ecosystem.
