About Me

I am a Ph.D. student in the Faculty of Engineering and Information Technology at the University of Technology Sydney (UTS), supervised by Prof. Yunchao Wei and Prof. Ling Chen . I received my bachelor’s degree in School of Data and Computer Science (currently School of Computer Science and Engineering) from Sun Yat-Sen University (SYSU). Before UTS, I spent a wonderful year working with Prof. Xiaodan Liang at SYSU as a research assistant.
My current research interests are in Computer Vision and improving vision models with advanced Machine Learning algorithms, such as Automated Machine Learning, Few-shot Learning and Continual Learning. Specifically, I have recently worked in:

• Computer Vision: Object detection, Segmentation and Human pose estimation
• Machine Learning: Self-supervised pre-training, Continual learning, Few-shot learning, Weakly-supervised learning and Automated machine learning.
