👋 Hi, I'm Yuhan

I am a computer science PhD candidate at the Human-Computer Interaction Lab at Princeton University, advised by Dr. Andrés Monroy-Hernández. Previously, I earned my Master's degree at Carnegie Mellon University, where I worked together with Dr. Haiyi Zhu, Dr. Steven Dow, and Dr. Robert E. Kraut. My research interests lie in human-computer interaction and social computing. I'm especially interested in exploring and developing decentralized sociotechnical systems.
