I am currently a postdoctoral associate at the National Engineering Research Center of RVC, working with Prof. Min Liu. Prior to this, I obtained my Ph.D. in Computer Science from Nanjing University of Science and Technology, where I was advised by Prof. Jinshan Pan at IMAG Lab.

My research interests include

• Low-level vision: super-resolution, deblurring, night photography rendering, HDR imaging, and AI ISP
• Event-based visual enhancement
• AI rendering for gaming
• 3D reconstruction

Never stop looking for collaboration, kindly contact me via email.
