Hi! I am a Ph.D. Student in Computer Science at Johns Hopkins University, advised by Angie Liu. Prior to that, I was at VinAI and obtained a B.S.E. in Information Technology from PTIT-Hanoi, under the supervision of Toan Tran and Dinh Phung.

Research Interests [Research Statement]: I want to develop reliable Machine Learning (ML) systems that can support people in high-stakes applications. My research focuses on improving efficiency, uncertainty, and robustness in ML algorithms for sequential decision problems.
