Board of Directors

Henri Vallés



Henri has spent most of his adult life associated, in various degrees, with universities of the Caribbean, Spain and Canada. His strong interest in the natural sciences led him to pursue a BSc in Biology at the University of Oviedo (Spain), an MSc in Natural Resource Management at the University of the West Indies (Barbados) and a PhD in Biology at McGill University (Canada). A few years ago Henri worked as a technical advisor to the Haitian government in issues pertaining to the development of fisheries and he is now a full-time Lecturer in Ecology at the University of the West Indies (Barbados) and an associate researcher within the FORCE project. As part of this diverse background, Henri is fluent in Spanish, French, English and Haitian creole. His post-graduate work focused on investigating settlement and post-settlement dynamics of coral reef fishes and in improving the methods we use to study the transition that most reef organisms make when moving from the open sea as larvae to the reef. Although still very much interested on issues pertaining to the population dynamics of reef organisms, Henri’s main line of research over the past few years has steered toward issues more directly related to improving the management of coral reef resources. He is currently working on the identification and development of simple indicators of the status of reef fish communities for ecosystem-based fisheries management in the Caribbean.

Joanna Pitt


Vice Chair

Joanna is the Marine Resources Officer for the Bermuda Government’s Department of Environment and Natural Resources, a post she has held since 2008.
