I am an Assistant Professor with the Department of Computer Science at University of Massachusetts, Boston (UMB) where he leads the Mobile Security and Privacy (MobSP) Lab. Prior to joining UMB in Fall 2015, I was a Postdoctoral Researcher (with Prof. David Kotz, FIEEE) at Dartmouth College, Hanover, NH in THaW project from National Science Foundation. I received the PhD degree (awarded Outstanding Achievement in Graduate Studies) in Electrical and Computer Engineering (under Prof. Sherman Shen, FIEEE and Prof. Xiaodong Lin, FIEEE), University of Waterloo, Canada, in 2013. I received the BSc and MSc degree in Computer Science from Shanghai Jiao Tong University, China, in 2006 and 2009, respectively. My research interests are Security and Privacy for Mobile Healthcare, Internet of Things, and Wearable Computing. My Google Scholar H-Index is 37 as of Jan., 2018. Here is my CV. [PDF].

I am looking for self-motivated Ph.D. students who are interested in cyber security research! Please email me your C.V. if interested.
