About Me

I am a Ph.D. student at National University of Singapore, advised by Prof. Yang You. I received my B.Sc. in Computer Science from Nanjing University in 2021. I spent one year in iCyPy at UC Berkeley from Apr. 2020, supervised by Prof. Alberto L. Sangiovanni-Vincentelli and Dr. Xiangyu Yue.

Research Interest

My current research mainly focus on Video Generation, Efficient ML (machine learning) and Large-scale DL (Deep Learning) Optimization.

  • Video Generation: large-scale video generation model, video control and alignment.
  • Large-scale DL Optimization: optimizer design (faster, memory-efficient, robust, etc.), optimizer explanation, data-model-algorithm connections.
  • Efficient ML: computation-efficient training (accelerated optimizer, large batch training, incremental learning), memory-efficient training, efficient inference.

I am always happy to chat about interesting research ideas.
