I am a Ph.D. student at Inria Lille - Nord Europe in MODAL team since January 2020. I work under the direction of Christophe Biernacki and Hemant Tyagi on inverse problems on graphs (mostly clustering and matching problems). I’m particulary interested in iterative methods including model-based approaches like EM algorithms and model-free approaches like generalized power methods. I’m also familiar with spectral methods, perturbation theory and concentration inequalities.
