### Research interests

My current research is on non-linear PDEs, in particular on the orbital stability of standing-wave or traveling-wave solutions to several evolution equations (as the non-linear Schrödinger and the non-linear Klein-Gordon equations). My interests include problems and variational techniques strictly connected with the orbital stability, as the existence and the local uniqueness of dispersive equations, symmetries and multiplicities of solutions to non-linear elliptic equations, symmetric rearrangements and concentration-compactness theorems. My Ph.D. thesis is on the spectral flow for paths of bounded operators on a Banach space. In infinite-dimensional Hilbert spaces the spectral flow is a group isomorphism. The main result of this work is highlighting a natural connection between the spectral flow and properties of the Banach space environment. Such relation can be illustrated in the space product $\small E\times E$: a loop of index $k$ exists if and only if $\small E$ is isomorphic to a closed subspace of co-dimension $k$; if the linear group of $\small E$ is simply connected, then the spectral flow is injective.
