Biography

I am a final-year Ph.D. candidate in the Computer Science Department at the University of Chicago and my advisor is Prof. Nick Feamster. And I received my Master of Science degree within Ph.D. at UChicago in the Summer of 2022 and my Bachelor of Engineering degree from Yingcai Honors College at UESTC. 
 
Before coming to UChicago, I was the CEO of a start-up Dominity Security Co., Ltd. I am a Research Intern at Conviva mentored by Prof. Vyas Sekar, and a Research Consultant at LangSafe.ai, and I also had my internship at FedML, Virginia Tech, Qihoo 360, MSRA(short-term visit), KnowWhy, and Tsinghua NISL.
 
My research interests lie in the intersection of networking, security, and machine learning systems, with my work often focusing on network traffic analysis, cellular networks, the Internet of Things, and cyber-physical systems. My work has been recognized and published in top conferences and journals such as USENIX Security, SIGMETRICS, CoNext, and UbiComp.

I serve as the head of NSF ACTION AI Institute student advisory council. And  ACM IMC and USENIX NSDI as a PC member and a member of the pre-review task force, and he is also a reviewer of USENIX ATC, IEEE INFOCOM, IEEE TDSC, etc. Additionally, my research has been featured in multiple media outlets, including Forbes, The Wall Street Journal, and ACM TechNews.
 

Overview of My Research

(First or co-first authored papers/projects are in Italics.)

Digital Well-being & Security

 

What’s New? 

  • Excited to become a reviewer of NeurIPS 2024!
  • I am very grateful for the warmest welcome extended to me by Prof. Brighten Godfrey and Prof. Tianyin Xu at the UIUC SysNet seminar. The community is super kind and insightful!
  • Immense gratitude to Prof. Zakir Durumeric and Dr. Gerry Wan for hosting my talk at the ESRG of Stanford University! The visit was incredibly welcoming and intellectually enriching.
  • Glad to be invited as a TPC member of IMC 2024! 
  • Our recent work on the highly efficient ML-based traffic analysis system ServeFlow: A Fast-Slow Model Architecture for Network Traffic Analysis is now on arXiv! So are CATO and AC-DC.
  • Recently, I had the privilege of giving a talk on “Operational ML in Networking” at both Carnegie Mellon University and Emerald Inc., extending my sincere thanks to Prof. Peter Steenkiste and Prof. Srinivasan Seshan at CMU, and Prof. Dina Katabi at MIT for their gracious invitations.
  • How to generate high-fidelity PCAP traces using a Generative Model? Our latest work “Generative, High-Fidelity Network Traces” explores this question and has just been accepted by HotNets’23. Our full paper NetDiffusion: Network Data Augmentation Through Protocol-Constrained Traffic Generation has been accepted by SIGMETRICS’24. Huge thanks to Chase, Aaron, Arjun, Paul, Francesco, and Nick for making it happen!
  • Started to serve as the Head of the Student Advisory Council at the ACTION AI Institute. 
  • Our paper “LEAF: Navigating Concept Drift in Cellular Networks” has been accepted by CoNext’23! It is the first end-to-end work to characterize, explain, and mitigate concept drift in networking. Huge shout out to Francesco, Paul, Arjun, Nick, and our Verizon collaborators Hector, Tim, and Brian!!
  • We got our paper “AMIR: Active Multimodal Interaction Recognition from Video and Network Traffic in Connected Environment” accepted at UbiComp/IMWUT 2023. Shout out to Tarun, Ted, Jinjin, John, Sanjay, and Nick! Check out our website for released datasets, processed features, models, and analysis pipelines. 
  • Thanks to the invitation from Prof. Wenke Lee, I shared my research “Towards Data-centric AI for Robust and Secure Operations in Networks” at GaTech. Really glad to have the opportunity to talk to the great minds at GaTech!
