I am Yiming Shen, a first-year graduate student at the School of Software Engineering, Sun Yat-sen University, under the supervision of Associate Professor Jiachi Chen (陈嘉弛) and Assistant Professor Yanlin Wang (王焱林). Currently, I'm working as a Security Research Intern at the Skyward Lab of Ant Group.

My research interests center on domain-oriented software security, specifically LLM4Security and program analysis for blockchain and LLM applications. 

I am seeking Ph.D. opportunities for Fall 2027. Please contact me if you are interested.
