Luis Enrique Fernández Machado

Ph.D. student in Mathematics

        
       I am currently first year Ph.D. student in Mathematics in France, employed by the Centre national de la recherche 
       scientifique (CNRS) and as a Marie Sklodowska Curie fellow co-funded by the European Commission through the 
       Cofund MathPhdinFrance program.

       I work in the Institut Denis Poisson at the Université d'Orléans and in the CERMICS lab of the École nationale des 
       ponts et chaussées (ENPC). My Ph.D. supervisors are Romain Abraham, Professor at Université d'Orléans, and 
       Jean-François Delmas, Professor at ENPC. 

       Currently, my research focus is on the field of community detection in dense labeled random graphs with particular 
       interest in the more general setting of the Labeled Stochastic Block Model (LSBM).
