Associated Researcher at DeustoTech, University of Deusto, Basque Country, Spain. Former postdoctoral researcher at DeustoTech (2017-2022) and AI researcher at Sherpa.ai (2022–2024).

I got my PhD summa cum laude from the University of the Basque Country (EHU) in 2016, within the ERC project NUMERIWAVES.

My research interests include the analysis, simulation, and control of dynamical systems and, more recently, the mathematical foundations of Machine Learning and the integration of Artificial Intelligence into control theory and dynamical modeling. Specifically, my expertise covers:

  • Control theory for nonlocal PDE models, such as hyperbolic, parabolic, and dispersive fractional equations, memory-type dynamics, and PDEs with integral potentials;
  • Numerical analysis for local and nonlocal PDEs with control or optimization purposes;
  • Stochastic and data-driven approaches to control and optimization problems;
  • Integration of ML with control theory, focusing on learning-based feedback design and hybrid mathematical–AI frameworks;
  • Mathematical analysis of learning algorithms, exploring their structure through tools from dynamical systems, optimal control, and variational analysis.

My research activities also include collaborations in electrical and control engineering, particularly on the modeling, stability analysis, and control of power grids, developed jointly with the University of Mondragón and several industrial partners in the Basque Country. More recently, I have become involved in biomedical research projects, where I apply mathematical modeling and AI-based methodologies to the study of healthy aging.

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.
