About Me

I am currently a postdoc fellow, supervised by Prof. Kin-Man Lam, in the department of Electrical and Electronic Engineering, the Hong Kong Polytechnic University.

My research interests include image/video processing, restoration and enhancement (e.g., image/video super-resolution, image/video denoising, high dynamic range imaging, etc.), robust machine learning (e.g., domain adaptation and generalization.), deep generative models (e.g., diffusion models and flow matching), and AIGC-related topics.

(News): I am actively seeking new full-time opportunities. I am currently authorized to work in Mainland China, Hong Kong, and Canada (pending OWP Visa approval). I am also open to considering opportunities in other locations, provided that a working visa sponsorship is available.

Responsibilities include:

  • The core member in the project ``online video restoration and enhancement system" is responsible for investigating deep spatial-temporal models (i.e., RNN, LSTM, Transformer, etc.) for real-time video processing.
  • Proposed a novel knowledge transfer method based on the optimal transport theory. The performance of the lightweight models can be improved by 0.15 dB without increasing model complexity. The proposed method can significantly accelerate the running speed by 400%.
