I am a forth-year (2016 - present) Ph.D. candidate in the Department of Computer Science at the State University of New York at Buffalo (UB), under the direction of Prof. Wenyao Xu at the Embedded Sensing and Computing (ESC) Lab. I earned my B.S (2009 - 2013) and M.S (2013 - 2016) degree in Electronic Engineering from Hangzhou Dianzi University (HDU).

My research interests focus on Internet-of-Things (IoT), Cyber-Physical Security, Emerging Technologies and Applications (e.g., Smart Health).


[2019.12] I have enjoyed a great fall semester at Samsung Research America (Mountain View, CA).

[2019.11] FerroTag (ACM SenSys 2019) won the Best Paper Award.

[2019.11] Join the IEEE S&P 2020 Shadow PC.

[2019.05] I will teach a course (CSE460 Data Models and Query Languages) in Summer 2019.

[2018.12] E-Eye (ACM SenSys 2018) is the first wireless tool to detect hidden electronics in the field, such as buggs and hiddencameras. A US patent is granted upon this work and licensed to multiple industrial players.

[2018.12] The mRehab team wins the finalist award (5 out of 74 teams) in NYS Department of Health Aging Innovation Competitions (read more).

[2018.10] The research work on "Fingerprinting 3D Printers" (ACM CCS 2018) drives emerging challenges of abusing 3D printers for unethical and criminal activities. Our product PrinTracker receives tremendous attentions from over 50 public media outlets, including VICE , CNET , ZDNet and New Atlas.
