Hi there! I am a PhD candidate at University of Alberta. My research interests lie in Human-computer interaction, Affect (emotions), and User-centred design. My PhD project focuses on understanding how people's affect and cognitive demands vary when interacting with emerging learning systems and the potential behavioural patterns related to these changes. This work involves studies with human subjects and multimodal analysis with data from scales, eye tracking, physiology and interaction logs. The goal is to provide insights that inform user-centred adaptation, which can enhance experiences and improve performance. For my Master's thesis project, I constructed a remote communication system with mixed reality and gesture interactions to provide a feeling of companionship.

I am actively looking for a research position or intern starting in 2025.
