hi, i'm yuxi

I am a Distinguished Postdoctoral Research Fellow at Northeastern University's Khoury College of Computer Sciences.

I formally examine how the ever-deepening entanglement of algorithmic technologies and digital services into society has resulted in concrete harms to people’s privacy. These entanglements have necessitated a recalibration of what privacy fundamentally means to people. In parallel, I create uplifting, social designs to help people navigate these challenging, changing contexts.

My work employs a combination of speculative design and traditional HCI methods. I publish at top venues in human-computer interaction (CHI, CSCW), security and privacy (IEEE S&P, USENIX Security), and AI ethics (FAccT). My research has been supported by a Georgia Tech President's Fellowship and a JP Morgan Chase AI Research Fellowship.

At Northeastern, I work closely with Alexandra To. I earned my PhD in Computer Science in 2024 from Georgia Tech's School of Interactive Computing, where I studied human-computer interaction and computer-supported cooperative work under the co-advisement of Sauvik Das and Keith Edwards. Prior to my PhD, I worked with Blase Ur at the University of Chicago.
