—-“I am currently a postdoctoral researcher in the Department of Computer Science at Hong Kong Baptist University. My research interests include user modeling, human-computer interaction, and conversational recommender systems (CRS). I earned my PhD from the University of Duisburg-Essen in 2025, where my research focused on interaction behavior analysis in CRS. Prior to that, I completed my Master's degree in Computer Engineering at the same university in 2019, during which I gained internship experience at Bosch and Volkswagen. I hold a Bachelor's degree in Computer Science from Zhengzhou University in 2015.”
