I am a PhD student at Fondazione Bruno Kessler (FBK) and European Laboratory for Learning and Intelligent Systems (ELLIS), under the supervision of Bruno Lepri (FBK), Andrea Passerini (University of Trento) and Manuel Gomez Rodriguez (Max Planck Institute for Software Systems). My research interests relate to fair & explainable AI topics, focusing on algorithmic recourse, counterfactual explanations and user-aware decision making systems.
During the PhD, I also interned at X, the moonshot factory (Google X) where I worked on Large Language Models (LLMs) applied to program synthesis supervised by Dr. Rishabh Singh in Mountain View, CA.
Before the PhD, I was a Research Scientist at VUI, Inc., a Boston's startup building innovative conversational agents and a Research Assistant in the Structured Machine Learning Group (SML) at the University of Trento, Italy.
During my undergraduate studies, I interned at CERN (2019), and I spent a semester at the University of Edinburgh (2018) as an Erasmus student. I also participated in the Google Summer of Code (2017) as a Software Developer for Shogun, a machine learning library. I received my Bachelor and Master’s degree (cum laude) from the University of Trento in 2017 and 2020 respectively. I also obtained a scholarship for my academic performance through my undergraduate studies.
In my free time, I enjoy climbing, hiking, reading and chess. I also spend a lot of time thinking about how to (safely) automatize human activity with (explainable and fair) intelligent agents.
