Hi there! As an HCI and User-centered Design scientist, my research interests lie in Affective Design, Lifelong Learning, Subjective Well-being. A core research passion is designing technologies that enrich affective experiences. My PhD work focuses on understanding people's emotional and cognitive demands when interacting with intelligent systems (e.g., game, simulators, AI pedagogist) and potential behavioural patterns (e.g., interaction, eye) related to these changes. I conduct interdisciplinary studies (e.g., language literacy, CS edu, healthcare) with varied populations (e.g., kids, university students, adult professionals). My work informs user-centered adaptation, which enhances experiences and improves performance. My recent work at VIXI Lab involves develop tools to support happiness for knowledge workers. My master's study focused on using mixed reality and gesture interactions to provide a feeling of companionship.

I am actively looking for a research position.
