About Myself

I am currently a fourth-year Ph.D. Candidate of Electrical and Computer Engineering at Rutgers, The State University of New Jersey, New Brunswick, advised by Prof. Yingying (Jennifer) Chen (Fellow of IEEE, ACM, AAIA, NAI). I obtained my Master’s degree of Computer Science at Rutgers, the State University of New Jersey, New Brunswick, and my Bachelor’s degree of Information Security from Huazhong University of Science and Technology, Wuhan.

Research Interest

• Security and privacy for mobile systems, including AR/VR systems (MobiCom 2021, S&P 2023, CCS 2023, CCS 2024), wireless and mobile sensing systems (ICCCN 2023, CCS 2023)
• Robust and trustworthy ML/AI systems, including audio attacks (MobiCom 2022, MobiCom 2024) and defenses (CCS 2021) in voice assistant systems
• Mobile sensing and computing (MASS 2021, CNS 2024)
• Smart and mobile healthcare (JERM, MobiSys 2023)
