👨🎓 About Me
Hi! I am currently a master student at Intelligent Transportation Lab, Institute of Systems Engineering, Department of Automation, Tsinghua University, advised by Prof. Jianming Hu. Additionally, I work as a research intern at AIR-DREAM Lab of Institute for AI Industry Research (AIR), Tsinghua University, advised by Prof. Xianyuan Zhan. I am also fortunate to work closely with Prof. Dorsa Sadigh at Stanford. I got my bachelor’s degree in June 2022 from the Department of Automation, Tsinghua University.
My research interest broadly lies in advanced data-driven learning theory and algorithms on decision making and optimization, such as reinforcement learning (RL), as well as their promising applications on autonomous driving and robotics. However, over recent years, criticism against RL continues to pour regarding its limited real-world applicability. Specifically, I therefore pay much attention to bridging the complex and intractable sim-to-real gaps that potentially deteriorate RL policies, seeking more practical solutions for real-world deployment.
