I am currently pursuing my Ph.D. degree (supervised by Quan Li) at the School of Information Science and Technology, ShanghaiTech University.
My research interests include Explainable AI and Human-in-the-loop ML, particularly within the realm of Social Computing. I develop visual analytics systems with innovative AI models to enhance the interpretability of AI-related applications and make them more user-friendly.
