Welcome

I am looking for motivated PhD students to work on self-supervised learning, point cloud recognition, 3D generative learning etc. 

Scholarships are available [link]. Drop me an email if you are interested.

Bio

I am now working as a research scientist at Institute for Infocomm Research (I2R), Agency for Science, Technology & Research (A*STAR), Singapore. I obtained my PhD degree from School of Computer Science, University of Adelaide, in Dec. 2015, under the supervision of 

Prof. Chunhua Shen.

I am listed among the World’s Top 2% Scientists by Stanford University (Single year 2021).

Research Interests

Machine Learning: Representation learning, Few-shot learning, Unsupervised learning, Deep generative models, etc.

Applications: Computer vision, Robotic vision, Medical image analysis, etc.

Academic Services

I am serving as an associate editor for IEEE Transactions on Circuits and Systems for Video Technology (Jan 2023 - Dec 2024). 

I also serve as reviewers for top-tier conferences and journals including CVPR, ICCV, TPAMI, TNNLS, TIP, etc.
