Welcome

I am an assistant professor at the University of Hawaiʻi at Mānoa, appointed by Electrical & Computer Engineering Department and Department of Information and Computer Sciences. I received my Ph.D. in Computer Science & Engineering at Michigan State University, US, in 2024, an M.S. in Computer Science from Ball State University (fully funded with Research Assistant Scholarship), US, in 2019, and a B.S. in Communications Engineering from Chongqing University of Posts of Telecommunications, China, in 2015. Prior to joining the University of Hawaiʻi, I was a research scientist at Samsung Research America (Knox security team) and Amazon (ML security team based in San Diego). My research interest includes trustworthy AI, mobile system & sensing. In particular, I am interested in research real-world AI applications, such as voice ID systems, smart speakers, mobile applications, watermarks, and wireless communication systems. I try to find the Vulnerabilities and potential fix solutions.

Openning: I am actively seeking highly-motivated students for Ph.D. or Research Intern positions. If you are interested, please send me your CV, transcripts, and brief descriptions your research interest
