I'm a Ph.D student from CS Department, USC since 2014 Fall. I work in Analysis of Network Traffic (ANT) group with my advisor Prof. John Heidemann at Information Sciences Institute (ISI).
I received my B.S. in Telecommunications Engineering from Beijing University of Posts and Telecommunications in 2014.
My research interests are Internet traffic analysis and measurement-based cybersecurity. I previously focused on detecting and explaining ICMP filtering in the Internet and detecting IoT devices by passive network measurements for security purposes (If you happen to own an IoT device, here is how to help). I am currently working on developing source-end defense to IoT-based DDoS attack.
Besides my research, I'm a huge fan of basketball. Occasionally, I go surfing and snow boarding.
