I am an Assistant Professor in the School of Design at the Hong Kong Polytechnic University and direct the Little Design Lab. Residing at the intersection of Child-Computer Interaction, Design, and Learning Sciences, my research primarily focuses on studying and designing equitable and playful learning experiences and technologies for young people, investigating the roles that social context plays in supporting such learning, and innovating design research in educational contexts. Additionally, some of my research and design practices extend beyond learning and children's contexts to broader design and HCI research, such as reflecting on design methodologies.

Before joining PolyU Design, I was a Temporary Research Faculty in the Creative Communities research group at the University of Colorado Boulder and once a research intern in the Berkman Klein Center for Internet and Society at Harvard University. I earned my Ph.D. in Information Science from the University of Colorado Boulder, Master's degree in Design from Shanghai Jiao Tong University, and Bachelor's degree in Industrial Design from Zhejiang University.
