I am a Postdoctoral Fellow in the Networks Data Science Group at IMDEA Networks Institute, and a Machine learning researcher at NetAI, a mobile network intelligence startup.
During my PhD (Cum Laude) in Telematics Engineering at Carlos III University of Madrid, I studied how we can understand Societal Phenomena and optimize network operations through the lens of Mobile Network Metadata. Also, I had the opportunity to plan, implement, and communicate computational research projects based on large-scale datasets. While closely collaborating with several academic researchers from different countries and major European industry players, such as Telefónica and Orange.
A big part of my PhD was carried out as an intern and visiting roles, including:
Research Internship at Cisco ThousandEyes in Crete, Greece, under the supervision of Antonis Chariton and Sergio Freitas. We analyzed the impact of exceeding the Maximum prefix limit in BGP and its relationship to peer connectivity.
Visiting PhD student in the Social and Urban Networks Lab at the Network Science Institute, Northeastern University in Boston, USA, under the supervision of Prof. Esteban Moro. We analyze how mobile apps can be used to understand election outcomes and political polarization.
Visiting researcher at Telefónica Innovación Digital, Spain, supervised by Dr. Andra Lutu. Between February 2023 and August 2024 (1.5 years), we studied and measured the impact of energy-saving policies in the Radio Access Network (RAN) by analyzing large-scale datasets of KPIs and RAN deployment.
My research lines focus on network measurements, remote sensing, and ML/AI solutions. With a specific interest in:
However, I have always been passionate about everything related to Human mobility, Social disparity and inequality, and combinatorial optimization.
I like being part of the community, which motivates me to contribute to the Technical Program Committee (TPC) for PAM 2026 & 2025, the TPC shadow for ACM IMC 2025 & 2022, and the TPC for the 1st IEEE Workshop on Quality of Data in Network Telemetry.
Also, as external reviewers for conferences and journals like:
In addition, I helped organize conferences such as PAM 2023 and Netmob 2023, and I participated in the Madrid Science Fairs of 2023, 2024, and 2025.
I supported Professor Marco Gramaglia as a Teaching Assistant at UC3M in the Access Networks and Shared Media course for undergraduate students of Telematics Engineering & Sound and Image Engineering.
Some of my work has appeared in IEEE INFOCOM (x3), IEEE SECON (x2), ACM IMC, and IEEE/IFIP TMA. For updated bibliometrics, you can check my Google Scholar profile.

For the first time in Cuba, we use Location Update records from the mobile phone network to generate origin-destination matrices in Havana. We used 15-days telecom anonymized data from 2020 to approximate trips identified as sequences of cellphone towers. We projected these trips over transport areas and municipalities, and showed the plausibility of the fluxes by comparing it with known behaviour of the city and data from census and work-home survey.
The search for binary sequences with low auto-correlations (LABS) is a computationally hard discrete combinatorial optimization problem. We explore two physically inspired algorithms to explore the low energy space of this model. The greedy, T = 0, Monte Carlo (MC) method gets trapped in the exponentially many 1-Spin-Flip stable configurations, that are typically low in energy, but still far from the global optimum. The more elaborated Warning Propagation (WP) algorithm also gets trapped in local minima. However, these local minima, are more stable to spin flips than the ones obtained by the greedy MC. We also compare the behavior of both algorithms in randomized versions of LABS, showing that the low energy space of the 4-Spin model is easier to explore than the one of LABS.
Los geógrafos han concertado esfuerzos con epidemiólogos, matemáticos, especialistas en ciencias de la computación, físicos, demógrafos… para conformar una obra cartográfica inusual, marcada justamente por la mirada multi- y transdisciplinar, con un enfoque espacio-temporal de la epidemia en La Habana, epicentro casi sostenido de la enfermedad en Cuba. La elevada conectividad entre todos los territorios que integran la provincia se convierte en factor de potencial trasmisión del virus; de ahí la mirada diferenciada a la que hay que recurrir y que de alguna manera se presenta en este texto.
Primera mirada al aporte de ciencia e innovación de la Universidad de La Habana al enfrentamiento a la COVID-19 desde una perspectiva multidisciplinar. […] El volumen que presentamos no implica el cierre de un proceso, sino el balance del trabajo realizado en un período inicial, en medio de la fragua continua de estos tiempos. Lo anima la propia vocación de servicio de sus autores: poner al acceso público, sin dilaciones, la obra investigativa e innovadora que se ha ido gestando para que fructifique, para que se convierta en conocimiento compartido, apropiación de un saber y una experiencia a emplear, incluso, más allá de las fronteras nacionales. Plasmar la germinación pronta, desatendiendo la ponderación sabia que permite la distancia crítica, es imperativo en estos momentos. Aquí quedan las huellas de la incertidumbre con que grava la epidemia; de la incompletitud en el desentrañamiento de la operatoria del SARS-CoV-2 y de la enfermedad que produce; del empleo de información estadística que no ha pasado por los «reparos» de rigor en las bases de datos… pero está la fuerza de una ciencia y una innovación de altísima profesionalidad, que también deja referentes en lo concerniente a experiencia, metodologías y sistemas de conocimientos, de validez presente y futura. Queda, asimismo, la construcción de una memoria, de tanta importancia para la propia ciencia, para la Universidad y la educación superior en general, y para la nación.
