My main research interest is spectral analysis of matrix sequences from PDE and FDE discretizations, and other structured matrices (especially Toeplitz-like), using matrix-less methods, the theory of GLT sequences, and other techniques. I especially like non-Hermitian matrix sequences with peculiar spectral behaviour. Some current projects are,
My preferred research tools are Julia (with GenericLinearAlgebra.jl and GenericSchur.jl for high precision linear algebra and Pluto.jl for dynamic visualization and experiments), OEIS, RIES, Wolfram Alpha, a MacBook Pro 13", an AMD Ryzen Threadripper 3970X (32 Core, 256 GB RAM), an AMD Epyc 7502P (32 Core, 1024 GB RAM), clusters at UPPMAX, and an iPad Pro 12.9" with Notability.
