Lingdong Kong

  PhD Student, NUS


     

     

I am a second-year Ph.D. student 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 S-Lab, Nanyang Technological University, Singapore.

My research pursues to build robust and scalable 3D perception and generation models capable of being generalized across domains and scenarios, with minimum or no human annotations involved.

I am fortunate to have research attachments and internships at OpenMMLab, ByteDance AI Lab, MMLab@NTU, Motional, and Advanced Digital Sciences Center.

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