I am a DPhil student of WhiRL at University of Oxford, advised by Prof. Shimon Whiteson. I’m also a member of AIMS CDT. I’m generally interested in improving the efficiency and generalization of reinforcement learning (RL) to make it more applicable in real world. I mainly focus on meta-RL and multi-task RL to achieve this goal, with application in domains such as robotics and science.

Previously, I graduated from Tsinghua University with Bachelor in Electronic Engineering and Master in Computer Science, working on automated machine learning with Prof. Wenwu Zhu.
