Biography

I will be joining the Department of Computer Science and Electrical Engineering (CSEE) at the University of Maryland, Baltimore County (UMBC) in Fall 2025. I earned my Ph.D. from the Department of Computer Science and Engineering at Michigan State University, where I was advised by Professor Guan-Hua Tu and Professor Li Xiao. Prior to that, I received my B.S. degree from Zhejiang University in 2018. My research interests lie broadly in security, mobile networks and systems, IoT, formal methods, and vehicle-to-everything (V2X), with a recent focus on securing and innovating 5G and next-generation mobile network protocols and technologies.

 

I am actively seeking self-motivated students for Ph.D. or Research Intern positions. If you are interested, please feel free to email me at huyiwen [at] umbc.edu with the following materials: your CV, transcript, and a brief description of your research interest.
