About me

I am a 2nd year Ph.D. candidate jointly advised by Prof. Jin Song Dong at the Programming Languages and Software Engineering (PLSE) Lab under National University of Singapore (NUS), and by Prof. Yun Lin at the CoPhi Research Group under Shanghai Jiao Tong University (SJTU).

My research addresses a core challenge in human-agent interaction: how to make software agents capable and reliable in real-world digital environments. I design agents that reason about graphical user interfaces by grounding visual information in structured representations. I apply this work to Internet security and software testing, where agents help detect threats, uncover bugs, and verify that interfaces behave as intended.
