Hi, thanks for visiting! I’m Long (*), an incoming Ph.D. student at the Department of Computer Science, National University of Singapore (NUS). My research interests lie in the field of Natural Language Processing (NLP) and Machine Learning (ML). Nowadays, I am especially excited about making generative models more aligned with the human purpose.

I graduated from Nanyang Technological University, Singapore (NTU) where I was advised by Prof. Shafiq Joty. At NTU, I finished my B.Sc. in Mathematical and Computer Sciences with a nomination for SPMS Outstanding Undergraduate Award.

(*) my name means Dragon in Vietnamese context.




The topics I have been working on include:

  • Vision-Language
  • Question Answering & Generation
  • Text Classification
  • Code Understanding and Generation
  • AI Applications (Education, Recommender Systems)
