Hello👋! I am Mingzhe Li(李明哲), a second-year Ph.D student at University of Massachusetts, Amherst, advised by Prof. Shiqing Ma.

I received my B.Eng in Cyberspace Security from Wuhan University in 2025. Before my time at WHU, I completed three years of study at the No.1 Middle School Affiliated to Central China Normal University （华中师大一附中）.

My research focuses on artificial intelligence security and privacy, Responsible Generative AI, and Agentic AI.

You can find my CV here.

I am actively looking for a research internship for Summer 2027. Feel free to reach out!
