My main interest is the asymptotic spectral analysis of matrices. In this respect, I have worked on matrix sequences coming from the discretization of linear PDE, on random matrix polynomial with growing size and/or degree, on perturbation of Hermitian matrices, and on matrices utilized in iterative methods.
