๐ About Me
I am currently a PhD student in the School of Engineering and Computer Science at Victoria University of Wellington (since March 2025), supervised by Bastiaan Kleijn and Felix Yan. My research focuses on:
- Diffusion models for speech enhancement, especially under low-latency, real-time constraints.
- Broader interests in signal processing and generative models.
Prior to my PhD, I obtained a Masterโs degree in Information and Communication Engineering from Huazhong University of Science and Technology (HUST), and a Bachelorโs degree in Biomedical Engineering from Xidian University.
