Penghui Li Assistant Professor College of Computing and Data Science Nanyang Technological University | Google Scholar | GitHub |
I am an Assistant Professor at the College of Computing and Data Science, Nanyang Technological University. Previously, I was a Postdoctoral Research Scientist at Columbia University. I received my Ph.D. from the Chinese University of Hong Kong in 2023 and and my B.Eng. from the University of Chinese Academy of Sciences in 2019.
My research focuses on software system security and its intersection with AI, addressing security challenges across web, cloud, and agentic systems. Most recently, I have been building infrastructure to ground LLM-based software security agents with stronger guarantees.
I am looking for motivated students to work on broad security and privacy problems. Please see the openings for details. Current NTU students are especially welcome to reach out.
