My primary field of expertise is the analysis of Partial Differential Equations, both from the theoretical and from the numerical point of view, with a particular emphasis on non-local models and control theory. My contributions to the topic spread among different areas of PDE analysis, including:

  • The study of controllability properties of hyperbolic, parabolic and dispersive PDE, involving the
    fractional Laplacian, integral kernels, singular inverse-square potentials and/or variable degenerate
    coefficients, memory terms.
  • Numerical controllability for non-local parabolic PDE involving the fractional Laplacian.
  • Regularity results for non-local elliptic and parabolic PDE involving the fractional Laplacian.
  • Mathematical and numerical asymptotic analysis for the propagation of solutions of wave-like
    processes in a local and non-local setting.
  • Analysis and control of collecting behavior models and their micro-macro limit.

Besides, I am working on the development of mathematical and computational tools for the model, stability analysis, and control of hybrid AC/DC power grids. This is the core topic of two shared research project between our team, the University of Mondragón (Basque Country), and three industrial partners strongly committed with the topics of control and energy management.

Ph. D 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, we analyze 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, we computed an approximate but reliable solution, investigating its properties and its asymptotic behavior. This analysis has been repeated also in cylindrical and spherical geometry, both configurations being relevant in the description of the physical phenomena at the basis of our model.
