Hi, I'm Kam-Kwai
Postdoctoral Fellow
I am a Postdoctoral Fellow at the Hong Kong University of Science and Technology, working with Prof. Huamin Qu in HKUST VisLab. I received my Ph.D. from HKUST.
My research focuses on spatial interfaces for collaborative sensemaking. I design and study interactive systems that help people interpret data, communicate intent, and make decisions together across immersive, augmented, and hybrid environments. Drawing on data visualization, immersive analytics, and human-computer interaction, I build cross-reality interfaces for collaborative analysis, storytelling, and risk communication.
On the Job Market: I am seeking postdoctoral opportunities starting in Fall 2026 in data visualization, AR/VR, and HCI.
Research Focus
I study how spatial interfaces can support collaborative sensemaking when people work across different viewpoints, devices, and realities. My goal is to understand how interface designs in space can help groups build common ground, coordinate attention, and reason together about complex information.
I build cross-reality interfaces that combine visualization with speech, gesture, tangible interaction, and embodied movement when those modalities help make sense of data relationships, task structure, and dynamic context. I apply this perspective to collaborative visualization, immersive analytics, situated guidance, public-facing data experiences, and disaster-risk communication. Looking ahead, I am especially interested in systems that connect immersive simulation with analytical reasoning, enabling people with different roles, devices, or time horizons to make sense of complex situations together.
