I am a Postdoctoral Researcher at Telecom Paris, working in the S2A research team (Signal, Statistics and Learning), which is part of the LTCI Laboratory (Communication and Information Theory), inside the department IDS (Image, Data and Signal).

I am currently working on survey sampling, transfer learning and broadly speaking on machine learning problematics.

Before that, I was a PhD student in probability theory at Modal'X, under the supervision of Nathanaël Enriquez and Laurent Ménard.

I was working on random matrices and random graphs theory.

My research interests lie in the study of large random graphs and large random matrices. So far, the topics I have worked on include:

- Spectra of large random graphs;
- Eigenvalues and eigenvectors of large deformed random matrices;
- Asymptotic analysis of exploration algorithms on sparse random graphs.

- Spectral asymptotic expansion of Wishart matrices with exploding moments

- For the conference Random Matrices and Random Graphs, organized by the GDR MEGA (Matrices Et Graphes Aléatoires) at the CIRM (2019), I made a poster on spectral measures of spiked random matrices. You can find it here.
- I gave a talk at the 2018 edition of the conference Les probabilités de demain. It was a short introduction to Wigner and Marchenko-Pastur laws and their generalizations, in links with a work on Wishart matrices with exploding moments. You can find the record (in french) here.
