Bio

I am a PhD candidate at IMEC and Ghent University, under Prof. Wilfried Philips. Prior to this, I received my Master's degree in Applied Mathematics from Northwest A&F University. My academic and research interests are focused on the field of Inverse Imaging Problems, which I am deeply passionate about.My research interests primarily focus on tensor completion, hyperspectral imaging, and low-level vision. In my work, I enjoy applying mathematics to develop novel methods for tackling image processing problems. I have published several papers on these topics in IEEE Transactions journals such as IEEE TNNLS, TMM, TGRS, TCI, among others.
