About Me

Hi, I'm Fred. I am a PhD candidate at the Interdisciplinary Centre for Security, Reliability and Trust (SnT) at the University of Luxembourg focusing on Natural Language Processing (NLP). In parallel, I am currently working as a Data Scientist at Zortify, a startup developing NLP-based Human Experience Management tools. My research is focused on multilingual language models and cross-lingual NLP, with a focus on low-resource languages and parameter-efficient methods.
