Short Bio
I am a second-year master's student in Electrical Engineering and Information Technology at the Technical University of Munich .
I am doing research internship with Jiapeng Tang and Prof. Matthias Nießner at TUM Visual Computing Group.
I was working as a working student at ImFusion with
Mert Asim Karaoglu,
Dr. Benjamin Busam,
Prof. Nassir Navab.
I was a master's student of TUM-CVG,
TUM-DI-LAB working with
Prof. Daniel Cremers,
Dr. Yan Xia,
Dr. Chuanxia Zheng and
Weirong Chen.
I obtained my Master's degree in Computer Science from the CAD Research Center, Tongji University.
I did a research internship at Zhejiang University under the supervision of Prof. Yiyi Liao.
Before that, I received my B.Sc degree in Information and Computing Science from Department of Mathematics, Nanjing Tech University in 2021.
I was born on April 20th, 2000 in Huai'an, China.

An interesting thing about my surname is that in the dialect of my hometown, it's pronounced as "yí" instead of "jī" in Mandarin, which is exactly the same as the German pronunciation of "ji".
Just in case you didn't get it, the letter "j" in German is pronounced as “yott” (rhyming with “thought”).
That is why learning German has been a miraculous experience for me.
* P.S.: My bachelor's degree is in a branch of mathematics, although it looks more like computer science.
I took many mathematics courses during my undergraduate years, such as "Mathematical Analysis", "Numerical Analysis", "ODE", "Optimization And Operations Research", etc.

RE0: Recognize Everything with 3D Zero-shot Instance Segmentation
Xiaohan Yan*, Zijian Jiang*, Yinghao Shuai*, Nan Wang, Xiaowei Song,
Wenbo Ji, Ge Wu, Jinyu He, Gang Wei, Zhicheng Wang†
Scene Decompostion
Given 3D point clouds and multi-view RGB-D images with poses, Re0 leverages the 3D geometric information, projection relationships and CLIP semantic features for 3D zero-shot instance segmentation.

4D Half Gaussian Splatting based Endoscopic Stereo Scene Reconstruction
Tongji University Master's Thesis, 2025
3D/4D Reconstruction
Given stereo endoscopic videos of deformable tissues, this thesis proposes a 4D deformable half-Gaussian splatting framework with depth-prior initialization, temporal–spatial encoding, and lightweight Gaussian pruning for high-fidelity, real-time surgical scene reconstruction.
