Hi there! As an HCI and UXD scientist, my research interests lie in Affective Design, Human-AI Interaction, Subjective Well-being. My PhD project focuses on understanding people's emotional and cognitive demands when interacting with intelligent systems (e.g., game, simulators LMS, 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. Most recent work 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 or internship.
