About Me

I am a second-year Ph.D. student in Electrical and Computer Engineering at Duke University, advised by Prof. Neil Gong. Previously, I earned my Bachelor’s degree in Information Security (IEEE Honor Class) from Shanghai Jiao Tong University.

My research broadly lies in AI security, and I am currently focusing on prompt injection attacks and defenses for LLM applications and agents.

Please feel free to email me reachal dot wang at duke dot edu for any inquiries related to my research.
