Human–Computer Interaction · Affective Computing · AI for Healthcare
Le Fang
I am a Ph.D. student in Intelligent System and Interaction Design at The Hong Kong Polytechnic University, supervised by Prof. Stephen Jia Wang and co-supervised by Prof. Ying-Qing Xu.
My research lies at the intersection of multimodal interaction, HCI, AI, and data mining. I design practical healthcare technologies that translate computational advances into meaningful real-world impact.
