Je suis chercheur IRD au Laboratoire d'Etudes en Géophysique et Océanographie Spatiale (LEGOS UMR - IRD, CNRS, CNES & Université Paul Sabatier) à Toulouse (France). Mes recherches portent sur la dynamique des systèmes d'upwelling de bord Est (EBUS) de l'hémisphère sud, le long des côtes de l'Angola et de la Namibie dans le nord du système d'upwelling de Benguela, en collaboration avec le département d'océanographie de l'UCT (Le Cap, Afrique du Sud, depuis plus de 15 ans). Je suis spécialisée dans la dynamique équatoriale linéaire (propagation d'ondes à grande échelle) et les interactions air-mer à l'échelle régionale et à l'échelle du bassin Atlantique tropical. Je suis une modélisatrice numérique. J'utilise une méthodologie basée sur l'analyse comparative des observations (in situ et satellites) et une combinaison de modèles simples (linéaires) et complexes (modèles régionaux couplés à haute résolution). Je donne également des cours au niveau Master et License (cours de Master sur la dynamique des fluides géophysiques et sur les ondes océaniques (en France, au Bénin et au Vietnam), cours de Statistics au niveau maitrise (Afrique du Sud)) et je donne régulièrement des formations sur la modélisation régionale océanique. Dans le cadre de mes missions à l'IRD, j'ai été chercheur à l'Instituto del Mar del Peru (IMARPE, Pérou) de 2010 à 2012 et au Département d'océanographie de l'Université du Cap (UCT) de 2015 à 2019.
