Bio. I am a senior Research Scientist at DeepMind, focusing on Deep Reinforcement Learning. I pursued my Ph.D. at University of Technology Sydney (UTS), advised by Prof. Yi Yang. I received my Bachelor's degree from Zhejiang University in 2013, under the supervision of Prof. Yueting Zhuang and Prof. Fei Wu.
I spent two fabulous internships in Alphabet/Google's AI groups. In Spring 2017, I was a research intern at DeepMind, working with Dr. Hado van Hasselt and Prof. David Silver. And in Spring 2016, I was a research intern at Google Brain, working with Dr. Pierre Sermanet and Dr. George Toderici.
More details can be found in my CV.
