About Me

I’m a PhD student in Computer Science and Engineering at HKUST, under the supervision of Prof. Huamin Qu at VisLab. My research interests lie in Human-Computer Interaction, with a focus on accessibility technologies and educational games.

Before joining VisLab, I pursued my bachelor’s and master’s degree at Tsinghua University, obtaining a master’s degree in Computer Science and Technology (supervised by Prof. Yuanchun Shi), a first bachelor’s degree in Electrical Engineering, and a second bachelor’s degree in Digital Meida Art. I also accumulated 2 years of experience in the industry, working as a product manager in Xiaomi Corporation.

Research Interests

1. Accessibility Technologies: Exploring new interaction techniques that help people with visual impairment access and engage with visual information.

2. Educational Game Design: Raising awareness of social topics through engaging gameplay.
