Research Interest: Cybersecurity, Trustworthy AI, Mobile System & Sensing

Openings: I am looking for new PhD students to join my research team, if you are passionate about related research topics, please email with your CV and couple sentences about your research interest. I am excited to have you here to work with me together at Hawaii!

I successfully defended my Ph.D. dissertation titled "Toward private, secure, and robust AI-enabled voice services"
I am selected as the Artifact Evaluation Program Committee of MobiCom 2024.
I am selected as the Artifact Evaluation Program Committee of MobiSys 2024.
I serve as the external reviewer of IEEE Transactions on Mobile Computing (TMC) 2024.


I am an incoming tenure-track assistant professor at University of Hawaii at Mānoa, Electrical and Computer Engineering Department. Prior to this, I complete my Phd study at the Michigan State University, SEIT(SEcure and Intelligent Things) lab and eLANS (experimental Laboratory for Advanced Networks and Systems) lab. My research interests include signal processing, speech recognition, machine learning, AI-enabled mobile systems. I was co-advised by Dr. Li Xiao and Dr. Qiben Yan.

I received my MS for Computer Science at Ball State University, working with Dr.Shaoen Wu. I received my B.Sc for Telecommunication Engineering from Chongqing University of Posts of Telecommunications (CQUPT).
