About

Thanks for visiting! I’m Long (*), a first-year CS Ph.D. student at National University of Singapore (NUS) and Agency for Science, Technology and Research (A*STAR). I am advised by Prof. Kenji Kawaguchi, Prof. Kan Min Yen, Dr. Nancy Chen to study Human-AI Alignment.

I received my B.Sc. in Mathematics (Statistics) + Computer Science at Nanyang Technological University, Singapore (NTU) advised by Prof. Shafiq Joty. At NTU, I won the SPMS Outstanding Undergraduate Award 2023 (Outstanding Achievement).

My works are mostly published at top-tier NLP/ML conferences such as ACL, EMNLP, NAACL.

(*) my name means Dragon in Vietnamese context.
