I am currently a post-doctoral researcher in CyLabECE Department, CMU, advised by Prof. Marios Savvides. My research interests span computer vision, machine learning, deep learning, etc.

Prior to CMU, I was fortunate to be a joint-training Ph.D student (2017-2019) in UIUC/IFP group, advised by Prof. Thomas S. Huang.

I received my Ph.D from Fudan University working with Prof. Yu-Gang Jiang and Prof. Xiangyang Xue. I was a research intern at Intel Labs China and SenseTime Research, collaborating with Zhuang Liu, Jianguo Li, Yurong Chen (ILC, 2016-2017), Mingyang Huang, Jianping Shi (SenseTime Research).

Research Interest

My research focuses on the broad area of computer vision and machine learning. Specifically, I am interested in deep learning methods for object detection, fine-grained recognition, image/video captioning, etc. Recently, I focus on

  • Few-shot and zero-shot learning
  • Designing and training high-efficiency network structure
  • Video Analysis, including detection, captioning, summarization and prediction
  • Image Understanding, including visual question answering, captioning, fine-grained recognition and detection
  • Weakly-supervised/Unsupervised Learning
  • Low-bit Networks
