About Me

I'm a final-year PhD candidate in Computer Science at Sapienza University of Rome, where I'm advised by Prof. Walter Quattrociocchi. Currently, I'm a visiting researcher at the University of Toronto, working with Prof. Ebrahim Bagheri. My research interests lie at the intersection of Machine Learning, Network Science, and Computational Social Science, with a particular focus on understanding the dynamics of user interactions on social media, trying to find out if there's more to social media than just cat videos and memes!


My work has been published in high-impact journals such as Nature and has been recognized by both peers and media. A key component of my research involves conducting robust computational analyses on large-scale datasets and recognizing that online platforms serve as both mirrors and shapers of human behavior.


I'm a recipient of the Sapienza's CS "Departmental Excellence" Scholarship and have been fortunate to receive several grants for my research. I hold MSc and BSc degrees in Computer Science from Sapienza University of Rome and the K. N. Toosi University of Technology. Beyond academia, I've worked with several companies to develop AI-driven and cloud-based solutions.


I'm always excited to collaborate with fellow researchers. Over the years, I've had the pleasure of collaborating with amazing people from institutions such as the University of Washington, Stanford, the Complexity Science Hub, and many others. As a true believer in the network effect, I love connecting with others. Feel free to reach out, I'd be more than happy to have a quick chat!
