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. I am currently working on developing source-end defense to IoT-based DDoS attack. (If you happen to own an IoT device, here is how to help.)
