About Me

I'm Jie Cai (蔡杰), a Postdoctoral Researcher and Shuimu Tsinghua Scholar at Pervasive HCI Group in the Department of Computer Science and Technology at Tsinghua University, where I work with Dr. Chun Yu. I was an Assistant Research Professor at College of IST, Penn State University and co-led the Collaboration and Innovation Lab with Dr. John M. Carroll. I received my Ph.D. in the Ying Wu College of Computing at the New Jersey Institute of Technology, where I was supervised by Dr. Yvette Wohn and worked at the Social X Lab. My research has been generously supported by two NSF projects on social media content moderation: (1) Handling Online Risks and Creating Safe Spaces: Content Moderation in Live Streaming Micro Communities; (2) Augmenting Social Media Content Moderation.

My research is situated in Human-Computer Interaction (HCI) and Computer-Supported Cooperative Work (CSCW). I study the intersection of interactive media, platform governance, AI, and education, using mixed methods such as observation, interviews, surveys, and participatory design. My work examines both positive and negative dimensions of online user experience: (1) immersive interactions in emerging online spaces; (2) harassment, including racism and sexism, and content moderation in interactive social spaces; and (3) AI governance and AI education.

My research has been published in premier HCI venues, including CHI (three Honorable Mention Awards) and CSCW (one Honorable Mention Award). I actively serve the HCI community through leadership roles on organizing committees (ACM CSCW 2024, 2025, and 2026 publication co-chair; ACM CHI 2022 assistant to the technical program chairs; ACM IMX 2021 proceedings co-chair), program committees (AC for CSCW, CHI, and CHI PLAY), and workshop organizing teams (CHI 2023 and 2024). I have also been invited to give industry talks at Twitch and interviewed by the Center for Democracy and Technology to broaden the impact of my research.

🚀 Now Recruiting: Motivated Students!

I am actively looking for highly motivated students with interdisciplinary backgrounds (e.g., computer science, psychology, communication, policy, management) to join my projects.
New projects focus on AI governance, LLMs, and education, broadly defined.
