“My research interests are related to the analysis of Partial Differential Equations, in particular from the point of view of control theory. During the years of my PhD I have been concerned with the study of controllability properties of hyperbolic (waves), parabolic (heat) and dispersive (Schrödinger) PDEs, involving non-local terms, singular inverse-square potentials, variable degenerate coefficients or dynamical boundary conditions. At the moment, I am getting interested in non-local transport problems, derived from models of collection behaviour.”

PhD Thesis

On the controllability of Partial Differential Equations involving non-local terms and singular potentials

Advisor: Prof. Enrique Zuazua – Universidad Autónoma de Madrid and DeustoTech – University of Deusto – Bilbao, Spain
Description: In this thesis we study the controllability and observability of certain types of Partial Differential Equations, that describes several phenomena arising in many fields of the applied sciences, such as elasticity theory, ecology, anomalous transport and diffusion, material science, filtration in porus media and quantum mechanics. In particular, we focus on the analysis of PDEs with non-local and singular terms.

Master’s Thesis

A free boundary problem for the CaCO_3 neutralisation of acid waters

Advisors: Prof. Riccardo Ricci and Dr. Angiolo Farina – University of Florence, Italy.
Description: In this thesis is analysed a parabolic free boundary model arising from a problem of neutralization of acid waters via the filtration through calcium carbonate. After having developed the model according to the Physics, it has been computed an approximate solution, analysing its properties and its asymptotic behaviour. This analysis has been repeated also in cylindrical and spherical geometry.
