Short Bio

I am a third-year Ph.D. candidate at the University at Buffalo of New York, supervised by Dr. Changyou Chen. In general, my research interest includes:

·    Natural language process including multi-lingual models and text generation

·    Multimodal research including the interaction between natural language and computer vision

·    Deep generative models such as VAE and GAN

·    Deep reinforcement learning


My previous work focuses on learning better feature representations for long sequences and generating sequences with deep generative models, with applications to sentence generation and action generation. 


Before that, I received a master's degree from the Department of Electrical and Computer Engineering at the University of Michigan, Ann Arbor in 2018, and my bachelor's degree from the Department of Electrical and Computer Engineering at Central South University, Changsha, China in 2016.

  • May.2021: I will work with Facebook ai on multi-lingual and multi-modal research.
  • Nov.2020: I finished the internship with Amazon working on a multilingual language model for the natural language understanding unit for Alexa Conversation System.
  • Aug.2020: I finished the internship with Tencent AI research working on a document summarization system to automatically write summaries for posts on the game forums, which contains noisy data from the special domain.
  • July.2020: One paper has been accepted to ECCV 2020.
  • May.2020: One paper has been accepted to ICML 2020.
  • Dec.2019: One paper has been accepted to ICLR 2020.
  • Nov.2019: One paper has been accepted to AAAI 2020.
  • Aug.2019: I finished an internship with PlayStation working on physics-based character motion.
  • Jun.2019: My recent work for text generation was orally presented in the imitation workshop, ICML 2019.
