Essomanda Tchandao Mangamana is born in 1991. He obtained his bachelor degree in Mathematics, Statistics and Socio-economics Applications at the University of Kara (2012) and a Bilingual Master degree in Biostatistics at the University of Abomey-Calavi (2016). From 2017, he is unrolled in a PhD program in Biometry at the University of Abomey-Calavi and Applied Statistics at Oniris, Nantes Atlantiques (France). From the same year, he is also temporarily attached to teaching and researches at the Faculty of Sciences and Technologies of the University of Kara.

Research project 

As part of his PhD project, he works on multiblock data, which are paired by individuals.  More precisely, he aims at comparing in a unified framework some existing unsupervised methods and proposing new other methods for the description of the structure of multiblock data and the assessment of the relationships among them. In the same vein, for the purpose of predicting a response block of variables from several explanatory blocks of variables, he aims at comparing supervised methods and proposing new strategies for the analysis of multiblock data.
