Associate Professor in Mathematical-Physics at the University of Abomey-Calavi, Ezinvi Baloïtcha obtained his PhD in 2002 in co-supervision between Université de Liège, Belgium, and Université Paris XI Orsay, France, in the field of N-body Problems in non-relativistic quantum mechanics as well as the use of wave packet methods for charge transfer in Helium atoms. After successively two-year and one-year post-doc positions at Bristol University (England) and Université Paris XI Orsay, France, he returned to Benin in 2005 and got a permanent position at the University of Abomey-Calavi where he became Scientific Secretary of the International Chair in Mathematical Physics and Applications. Since 2005, he has been giving lectures in geometric optic, quantum mechanics, electromagnetism, fluid mechanics, wave theories and PDE. His research interests include the development of mathematical tools to study 1) circulation and surface conditions (mixed layer and salinity, barrier layer, circulation and meso-scale eddies) in the Gulf of Guinea and the equatorial and coastal upwellings and 2) the interactions between coastal upwelling, as well as Hamiltonian decompositions, quantum mechanics, and group theories.
