About me

I studied Mathematics and Computer Engineering at Universidad Autónoma de Madrid, then went for a double masters program in Language and Communication Technologies at Charles University in Prague and Malta University. I earned my PhD in computer engineering with a thesis on the computational treatment of Spanish Sign Language and SignWriting. Currently, I work as assistant professor at Universidad Complutense de Madrid.

Research lines

My research topic is Computational Linguistics, and I'm mostly centered on analysis and processing. I use both grammars and rules and machine learning, and nowadays I'm interested in combining deep learning with knowledge based approaches.

Currently, I'm focused on Sign Language, the natural language of the Deaf and Hard-of-Hearing communities, which presents very interesting challenges and insights due to its viso-gestual nature.
