Pingchuan Ma

I am a Full Professor at Zhejiang University of Technology. Before joining ZJUT, I was a postdoctoral researcher at the Hong Kong University of Science and Technology, supervised by Prof. Shuai Wang, where I also received my Ph.D. I was a visiting scholar at Sky Lab at UC Berkeley in 2024, hosted by Prof. Alvin Cheung. I have also worked as Chief AI Scientist at Myko, an AI startup, in 2023. I received my B.Eng. from the Beijing Electronic Science and Technology Institute. My research interests focus on building privacy-preserving and responsible intelligent systems.

I also co-founded CipherInsight Limited with Prof. Shuai Wang, where we build practical and developer-friendly cryptographic solutions.

I can be reached at Email address

Openings: I have multiple vacancies for PhD, Master, undergraduate, visiting, and postdoctoral positions. Please feel free to email me.
