Professional Bio

I'm a tenure-track assistant professor in the department of computer science at Wayne State University. I joined Wayne State University in Fall 2020. Before joining Wayne, I was a Ph.D student in the department of computer science at the University of Central Florida. To date, I published as a lead author several peer-reviewed research papers, including papers in top-tier conferences and premier journals, such as IEEE ICDCS, IEEE INFOCOM, and IEEE TMC, etc. I won the Best-in-session Presentation Award (SDN II) at IEEE INFOCOM (2017), the Outstanding Young Researcher Award from KISA (2018).

Recent Research Areas and Interests

  • Network Traffic Measurement: I'm interested in designing a cost-efficient data structure and algorithm (i.e., sketch) to realize the fast and accurate traffic measurement in a high-speed and resource-constraint network environment [INFOCOM'17][WiSec'17][ICDCS'19].
  • Wireless Security: I'm interested in studying the wireless secuirty inlcuding rogue access point detection [ICDCS'19], SDN-based WLAN intrusion detection system [INFOCOM'17], and channel interference [TMC'20].
  • Sampling Algorithm: In this project, we introduce a new concept of per-flow systematic sampling, aiming to provide the same sampling rate across all flows. In addition, we provide a concrete sampling method called SketchFlow, which approximates the idea of the per-flow systematic sampling using a sketch saturation event. We demonstrate SketchFlow’s performance in terms of accuracy, sampling rate, and overhead using real-world datasets. Experimental results show that SketchFlow outperforms SRS (i.e., sFlow) and the non-linear sampling method while requiring a small CPU overhead to measure high-speed traffic in real-time [INFOCOM'20].
  • Privacy: In this work, we conduct in-depth analyses of two state-of-the-art WF defense approaches of The Onion Router (Tor). Then, based on our new insights, we propose a novel defense mechanism using a per-burst injection technique, called Deep Fingerprinting Defender (DFD), which is designed to break the inherent patterns preserved in Tor user's traces by carefully injecting dummy packets within every burst [INFOCOM'20].

  • CSC 5290 - Cyber Security Practice (fall 2020, 2021): This course explores board security topics in the areas of network and operating systems. In particular, this course focus on providing hands-on experience leveraging various security tools, aiming to help students understand real-world security threats. It will cover both offensive and defense methods under a laboratory environment. Students are expected to finish lab assignments using real-world malware, exploits, and defense tools.
  • CSC 5991 - Network Programmability and Applications (winter 2021): This class covers the foundations and advanced topics in network programmability. By the end of the course, students are expected to know 1) the fundamental knowledge of network programmability, 2) router architecture and working flow, 3) state-of-the-art applications, and 4) opportunities and challenges.
