About Me

I am currently working as an Associate Professor at Harbin Institute of Technology. Prior to this position, I served as as a Research Fellow at Nanyang Technological University, collaborating with Prof. Alex Kot from Aug 2023 to Mar 2024. I was a Research Scientist at MBZUAI from Mar 2022 to July 2023 and a Research Fellow at Nanyang Technological University from Nov 2019 to Mar 2022, working with Prof. Shijian Lu. I received my PhD at Zhejiang University in Sep 2019, supervised by Prof. Yanpeng Cao, Prof. Jiangxin Yang, and Prof. Yanlong Cao. I obtained my bachelor's degree from Central South University in Jun 2014.

Research Statement

My research interests encompass scene understanding, unsupervised learning and multimodality. My goal is to develop techniques that can interpret complex scenes across various modalities with minimal human supervision.

Towards this goal, (I) during my doctoral studies, I focused on designing object detectors capable of processing visible and infrared images, particularly in situations where human-annotated labels were limited or unavailable. (II) Since graduating, I have been dedicated to developing unsupervised algorithms for object detection and semantic segmentation that can facilitate learning from unlabeled data across multiple modalities, such as images, videos and point clouds. (III) Most recently, I have been exploring the potential of unlabeled data to improve the effectiveness of large-scale vision-language models in various application fields.

Research Interests

  • Scene Understanding: Object Detection, Semantic Segmentation, Visual Reasoning

  • Unsupervised Learning: Unsupervised Domain Adaptation, Semi-Supervised Learning

  • Multimodality: Images, Videos, Point Clouds, Vision-Language Pairs, RGB-IR Pairs
