Tianshi Li
Assistant Professor
I’m an Assistant Professor at Northeastern University in the Khoury College of Computer Sciences, directing the PEACH (Privacy-Enabling AI and Computer-Human interaction) Lab. I’m also a core faculty member at the Cybersecurity and Privacy Institute at Northeastern University.
Come and join us if you’re interested in designing and building human-centered solutions for privacy! My more recent interest focuses on studying and addressing the emerging AI privacy issues from a human-centered perspective. Read my recent papers (1, 2, 3, 4) to learn more. Read my research statement to learn more about my doctoral dissertation on developer support for privacy.
I’m looking to hire PhD students starting in Fall 2025 with strong technical backgrounds in HCI system building and/or NLP, as well as experience in human-centered privacy research or good insights about human privacy issues. I’ll be attending COLM, UIST, HCOMP, and NeurIPS this year and look forward to talking with prospective students.
My research interests lie at the intersection of Human-Computer Interaction (HCI) and Privacy, with a focus on AI Privacy. I strive to address the increasing privacy issues in today’s digital world using a blend of human-centered problem understanding and technical problem solving. I conduct mixed-methods research to understand the privacy challenges situated in different stakeholders’ lived experiences, and build systems and conduct computational experiments to measure, model, and tackle these human-centered problems.
