About Me

I am a lecturer in the School of Computer Science and Informatics, which I joined in 2018 as a Research Associate, to work on the ERC-funded Starting Grant project FLEXILOG, alongside prof. Steven Schockaert. Previously, I was a Natural Language Processing (NLP) scientist at Savana (a Madrid-based company focused on delivering data-driven healthcare solutions), and before that I was a PhD student at Pompeu Fabra University (Barcelona). I have a background in English Linguistics and I have worked several years in second language teaching (English and Spanish). My research, in the area of Artificial Intelligence and NLP, is centered on meaning representation, computational semantics, multilingual NLP and modeling social media interactions. I am a Fulbright and laCaixa fellow and Erasmus Mundus alumni.
