About Me

I am a Sr. Staff Software Engineer at Palo Alto Networks. I received my Ph.D. in Computer Science under the direction of Professor Hongxin Hu and M.S. in Computer Science from Clemson University, and M.E. in Software engineering from University of Science and Technology of China. I like developing cool network security functions such as network firewalls and intrusion detection systems. I am also entusiatic about researching new security solutions to protecting new trending network applications, such as Software-defined networks (SDN), Network Functions Virtualization (NFV), and Internet of Things (IoT). Please check out my publications if you want to know more about my ideas about network security. My Google Scholar.
