I am a fourth-year PhD student at the School of Astronautics, Harbin Institute of Technology (HIT). I obtained both my Bachelor’s and Master’s degree from HIT in 2018 and 2020, respectively. My research has primarily focused on offline reinforcement learning, online adaptation, and task transfer. I aim to develop agents that can effectively leverage extensive offline data to adapt seamlessly to new environments while retaining prior knowledge. In addition, I am interested in Preference-based Reinforcement Learning (PbRL), which eliminates the need for meticulously designing reward functions. Recently, my research has shifted towards Large Language Model (LLM) alignment and Reinforcement Learning from Human Feedback (RLHF). I aspire to enhance the reasoning and continual learning capabilities of these models. Email / CV / Google Scholar / Zhihu / Github |
