About Me
My name is Dingdong LIU. I’m currently a PhD candidate in department of Computer Science and Engineering (CSE) at the HCI Initiative of HKUST, supervised by Prof. Xiaojuan, MA and Prof. Fugee, TSUNG since 2022. I also do research on humanoid robot with Prof. Bertram Emil SHI in Center for Aging Science. Prior to that, I earned my Bachelor’s Degree in Computer Science and Data Science at HKUST.
My research interest lies in robotics and Human-Computer Interaction (HCI), with a focus on exploring interaction mode between human and AI agents (chatbots, physical robots, etc.). I aim to gain insights into the capabilities that an agent should have to better support human in various tasks, including daily task planning and decision making, medical services, etc.
