About Me

I am a tenure-Track Assistant Professor in the Computer Science department at the West Chester University of Pennsylvania. I graduated from University at Buffalo - SUNY in the Department of Computer Science and Engineering under the supervision of Dr. Kui Ren.
My research interest broadly focuses on exploring the novel ideas and techniques to solve practical problems and security issues for mobile sensing and cyber-physical systems. In the context of mobile sensing systems, I am interested in smartphone-enabled crowdsourcing approaches that can help build large-scale information infrastructures conveniently at a very low cost. I also study cyber-physical system security from the physical layer, leveraging various related characteristics to enable inherently secure and dependable wireless communications.
In my spare time, I actively participate volunteer computing projects to power cutting-edge research in health, poverty, and sustainability:

My research on voice hacking has been featured in:
