I'm a Senior Research Scientist at Meta in London, working on long-term value modelling for ads ranking. My PhD is from the University of Cagliari (UniCa), where my research focused on Recommender Systems, end-user Explainability, and the intersection of Language Models with Knowledge Graphs. I've published at venues like SIGIR, RecSys, ECIR, and Elsevier KBS, with work spanning constraint-aware decoding for faithful generation (PEARLM), generative pretraining for knowledge-graph representation (KGGLM), and reinforcement-learning approaches to explanation quality.
Before Meta, I interned twice at Amazon Ads as an Applied Scientist on the Contextual Targeting team, working on multilingual category classification and later on LLM-based keyword recommendation. I was also a teaching assistant for Algorithms and Data Structures at UniCa across three semesters.
