I am currently an undergraduate student at Tongji University, , where I am actively involved in the TOPS Lab. Under the guidance of Professor Jian Sun and Professor Peng Hang, I am pursuing research at the intersection of cutting-edge technologies in autonomous driving systems and artificial intelligence.
My research interests are primarily focused on autonomous driving, with a particular emphasis on decision-making processes, reinforcement learning techniques, and the application of foundation models. I am passionate about developing innovative solutions to improve safety, efficiency, and the overall user experience in autonomous systems.
