Bio. I am a Principal Scientist at Tencent, focusing on Deep Reinforcement Learning, Large Language Models, especially in reasoning and planning. Previously, I was a Principal Scientist at Sea AI Lab, an Adjunct Assistant Professor at the National University of Singapore, and a Senior Research Scientist at DeepMind.

I received my Ph.D. from the University of Technology Sydney (UTS), where I was advised by Prof. Yi Yang. I earned my Bachelor's degree from Zhejiang University in 2013, under the supervision of Prof. Yueting Zhuang and Prof. Fei Wu.

During my early research career, I had the privilege of spending time at Carnegie Mellon University, the National University of Singapore, Google Brain, and DeepMind.
