Development of mathematical and statistical models (both for prediction and estimation) to support natural resource management. I give scientific advice on fishery resources and provide quantitative auditing of management performance. I have a special interest in developing an understanding of the mechanisms that are key to the sustainability of fisheries and relating such mechanisms to the processes of ecosystem management. I have worked for 30 years on research devoted to the assessment and management of worldwide fisheries and my research has been instrumental in the development of major management changes (fishing closures, fleet capacity reductions, catch quotas) in several fisheries. Presently, I am doing work in the assessment of tuna, billfish, sharks and reef-fish fisheries in the Atlantic and Pacific Oceans. I have current collaborative research links with scientists in fishery Institutions all around the world. I am the current Chair of the Scientific Committee of the International Commission for the Conservation of Atlantic Tunas (ICCAT).
