Johan Groeneveld is a senior marine scientist at the Oceanographic Research Institute in Durban, South Africa, and an honorary Associate Professor at the University of KwaZulu-Natal. He completed a PhD at the University of Cape Town in 2001, and has spent most of his professional career working on the impacts of commercial fisheries on fish stocks and on the marine environment in Western Indian Ocean countries, from South Africa in the south to the Sultanate of Oman and Arabian Sea in the north. He coordinated the development of the science plan for the nine nation Southwest Indian Ocean Fisheries Project (SWIOFP; 2008–2013), and led a multi-national team of researchers in the implementation of its crustacean component. During this period, he was the local cruise leader on RV Dr Fridtjof Nansen surveys to western Madagascar, Mauritius and the Mascarene Plateau. He has, since then, participated in many collaborative projects across the Western Indian Ocean region, mostly as the principal investigator, and often as a mentor to post-graduate students and young scientists. Johan has published widely in international scientific journals, and is on the editorial boards of both Fisheries Research and the Western Indian Ocean Journal of Marine Science.
