Greetings, I'm Oscar!
I am a postdoctoral researcher at the University of the Basque Country in the HiTZ center and IXA group. My research interests are focused on low-resource scenarios and particularly on low-resource Information Extraction. I obtained my PhD at the University of the Basque Country in 2024. I worked on zero and few-shot Information Extraction using entailment models and making LLMs learn to follow annotation guidelines.
Additional research interests include cross-lingual evaluations, LLMs for low-resource languages (particularly Basque), and data contamination in LLMs.
