Short Bio

I am a postdoctoral researcher at the Faculty of Informatics of the Università della Svizzera italiana (USI) in Lugano, Switzerland. I work in the Information Retrieval group, headed by Prof. Fabio Crestani.
In 2014, I received my Ph.D. in Engineering in Computer Science from Sapienza University of Rome, under the supervision of Prof. Stefano Leonardi. My Ph.D. Thesis focused on query-log analysis, optimization of IR systems through caching of search results and augmented inverted indexes, user-click analysis for recommendations of news and blog websites. Part of my research was conducted while I was intern at the Yahoo Research Lab in Barcelona (Spain) and at the Max Planck Institute for Informatics in Saarbrücken (Germany).
Before joining the IR group at USI, I was a postdoctoral researcher at Max Planck Institute for Informatics. I worked with Prof. Gerhard Weikum in the Databases and Information Systems group, and I was involved in projects on information extraction and on detection of privacy risks for web users.
