Julie Jiang

Hi! My name is Julie and I am a fourth-year PhD student in computer science at the University of Southern California (USC), Information Sciences Institute (ISI), advised by Dr. Emilio Ferrara. Broadly speaking, I am interested in learning about people—how user preferences, social cues, and external contextual factors influence and drive user behavior—in online settings such as social media and multiplayer games. I have had the pleasure to intern at TikTok/ByteDance, Snap (Computational Social Science team), Google, and Bose. I was also a recipient of the 2022 Snap Fellowship . Prior to USC, I obtained my B.S. from Tufts University in 2019, where I double-majored in CS and Math.

Outside of work/school, I enjoy playing the piano and cooking :)
