About Me


I am a first-year Ph.D. student in the Department of Computer Science at University of Southern California (USC) with Prof. Mohammad Soleymani of IHP-Lab. I'm also currently a visiting researcher at Image and Visual Representation Lab working with Dr. Tong Zhang and Prof. Sabine Süsstrunk .

Before that, I spent four wonderful years during my undergraduate at Dalian University of Technology and Technical University of Munich, studying Informatics and Information Engineering. I'm honored to be advised by Prof. Matthias Niessner and M.Sc Aljaž Božič during my praktikum at Visual Computing Group, as well as Prof. Angela Dai when I was a guided research student at 3D AI Group. I spent a wonderful summer in 2021 with Prof. Dan Xu at HKUST CSE.

I'm interested in Computer vision, Multi-View Stereo and Neural Rendering. My current research focuses include:

Research opportunities: I am happy to collaborate and/or answer questions about my research and my previous study at TUM and current PhD program at USC. If you are interested in research collaboration or have any inquiries about my experience, please send me an email. I especially encourage undergraduate students from DUT who want to work on interesting vision projects targeting top-tier conferences/journals to reach out.
