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 Dr. 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 have research attachments and internships at NVIDIA Research, OpenMMLab, MMLab@NTU, Motional, and ByteDance AI Lab.

I was the recipient of the National Scholarship (Ministry of Education, 2019) and Research Achievement Award (NUS Computing, 2023).

🦁 I am a member of AnySyn3D. We are open to discussions and collaborations in 3D scene perception and generation. Feel free to drop me an email if you find our research backgrounds a potential match.
