About me

Hello, I'm Xiwen, a PhD student in Computer Science.

I am 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 is about AI agents that see and understand the world as symbols to solve problems. I use this approach for web security, by manipulating these symbols to check, secure, or break systems, and for testing graphical user interfaces (GUI), by verifying that the symbols conform to expectations. Lately, I work with multimodal language model (MLLM) agents.
