Hello, stranger! My name is Alejandro. I am a multi and interdisciplinary researcher working at the intersection of natural language processing (NLP), human-computer interaction, information visualization, and digital humanities. I hold a PhD in Computer Engineering (2020) and a Master’s Degree in Intelligent Systems (2016), plus degrees in Computer Engineering and Software Engineering from the University of Salamanca.

In 2016, I joined the Visual Analytics and Information Visualization Group from the University of Salamanca in Spain. VisUSAL and later the GRIAL Research Group in Interaction and e-Learning, where I completed my PhD thesis, “Supporting Methodology Transfer in Visualization Research with Literature-Based Discovery and Visual Text Analytics”.

After completion of my PhD, I have been awarded two competitive postdoctoral fellowships: a Margarita Salas Postdoctoral Fellowship (2022-2023), and a Juan de la Cierva Postdoctoral Contract (2024-2025) in the NLP & IR Research Group at UNED. Since September 2025, I have been an Ayudante Doctor (Assistant Professor) in the department of Computer Languages and Systems at UNED.

I regularly serve as a reviewer for ACL, EMNLP, Computational Linguistics, IEEE VIS/TVCG and ACM CHI, among others, and have contributed to program and scientific committees in Digital Humanities and visualization (including VIS4DH).
