I am a 3rd year PhD student at LAMA (Université Gustave Eiffel) and CERMICS (Ecole des Ponts) under the supervision of Jean-François Delmas and Pierre-André Zitt, on the subject "Co-evolution models between large dense graphs and epidemics". My PhD is financed by the ED MSTIC and Labex Bézout.

My reserch interests are mainly epidemiological modelling using functional analysis (especially for positive operators on Banach lattices) and applied some ODE on Banach spaces. I am also intersted in random graphs, graphon theory, stochastic processes and topology.
