I am a second-year PhD candidate in Information Retrieval (IR) at the University of Amsterdam (IRLab), working with Prof. Dr. Evangelos Kanoulas and Dr. Mohammad Aliannejadi. I worked previously for two years in NLP and IR at Naver Labs Europe, in the Search and Recommendation Team. I received my Master from Grenoble INP Ensimag after an Erasmus Exchange at the Imperial College London.
My research mainly focuses on IR and conversational AI, working on distribution shifts, adversarial training, Large Language Models (LLMs) and Retrieval Augmented Generation (RAG).
