I'm a final-year Ph.D. student at University of Technology Sydney (UTS), under the supervision of Prof. Yi Yang. I received my Bachelor's degree from Zhejiang University in 2013. I was in the He-Zhijun Honor Class in the College of Computer Science, Zhejiang University, under the supervision of Prof. Yueting Zhuang and Prof. Fei Wu.

I am currently a research intern in DeepMind, working with Dr. Hado van Hasselt and Dr. David Silver. I was a research intern at Google Brain in 2016, working with Dr. Pierre Sermanet and Dr. George Toderici.

I was fortunate to visit the Informedia group, Language Technologies Institute, Carnegie Mellon University in 2012 and 2014, working with Dr. Alexander G. Hauptmann. I was also fortunate to visit Learning and Vision group, National University of Singapore in 2014, working with Prof. Shuicheng Yan.

My research interests include Deep Learning, Computer Vision and Reinforcement Learning. More details can be found in my CV.
