Lingdong Kong

I am a Ph.D. candidate in the Department of Computer Science at the National University of Singapore, under Prof. Wei Tsang Ooi. I am also closely with Prof. Benoit Cottereau from CNRS, Dr. Lai Xing Ng from A*STAR, and Prof. Ziwei Liu from Nanyang Technological University, Singapore.

My research pursues to build 3D perception and generation models that are robust, scalable, and generalizable across domains and scenarios, while requiring minimum human annotations.

I have been fortunate to collaborate with NVIDIA Research, OpenMMLab, MMLab@NTU, and ByteDance AI Lab.

🦁 I am open to discussions and collaborations in 3D/4D scene perception, generation, and understanding. Feel free to drop me an email if you find our research backgrounds a potential match.
