Hey visitor, got lost on the Internet? Good, I’ll take this opportunity to introduce myself!
I am Tiziano Piccardi, a postdoctoral scholar at Stanford University in the HCI group advised by prof. Michael Bernstein. My research interests lie at the intersection of HCI, AI, and CSS. I study the online information ecosystem and design ways to improve it (e.g., on social media platforms and Wikipedia). I am also a proud collaborator of Wikimedia Research.
I got my Ph.D. in CS from EPFL working with prof. Robert West in the Data Science Lab. During my studies, I had the opportunity to work at HP Labs and Xerox Research.
In the past, I founded a startup (Widerun), which combined virtual reality with fitness.
I am on the academic job market! If my research aligns with any relevant opportunities I’d love to chat!
