About Me

I am an Assistant Professor in Computer Science at Georgia Tech Shenzhen Institute. My research area is Cybersecurity. I am particularly interested in security and privacy issues in wireless networks, distributed systems, and more recently next-G mobile networks. I enjoy analyzing the fundamental security and privacy challenges in these systems and developing novel solutions under the assumption of zero or limited trust. I obtained my Ph.D. degree in Computer Science at Virginia Tech, supervised by Dr. Wenjing Lou. I received my master's degree in Computer Science from Tsinghua University and bachelor's degree in Information Engineering from Southeast University.
