I am a third-year 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 IoT, Cyber-Physical Security and Smart Health.


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

[2018.12] Best Graduate Research Award in 2018 at UB CSE.

[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'18) 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.
