Biography

I am a PhD student in the LanD group at Fondazione Bruno Kessler (Trento, Italy), under the supervision of Marco Guerini. My research focuses on the automatic generation of counter-narratives to fight online hate speech. More in general, I am also interested in human-machine collaboration approaches for data collection, dialogue generation and AI for social good.
