About Me

I am currently a research engineer at the Barcelona Supercomputing Center. My research is centered on investigating added toxicity in Multilingual Neural Machine Translation, utilizing decoder-only architectures for machine translation, enhancing the translation quality of low-resource languages, and improving the interpretability of large language models.
