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 current research interests cover numerous areas of PDE analysis and control, including:

  • different classes of non-local models such as hyperbolic, parabolic and dispersive fractional PDE, memory-type equations or PDE with integral potentials;
  • numerical analysis for local and non-local PDE with control purposes;
  • controllability properties of PDE with singular inverse-square potentials and/or variable degenerate coefficients;
  • analysis and control of collecting behavior models and their micro-macro limit;
  • stochastic methods applied to control problems

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

PhD’s Thesis. On the controllability of Partial Differential Equations involving non-local terms and singular potentials

Advisor: Prof. Enrique Zuazua – FAU (Erlangen-Nürnberg, Germany), Deusto Foundation-University of Deusto (Bilbao, Basque Country, Spain) and UAM (Madrid, 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. View the PhD thesis

Master’s Thesis. A free boundary problem for the CaCO3 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.
