I am an Associate Professor in Dept. of Computer Science at Purdue University. Previously, I was an Assistant Professor in the Dept. of Computer Science and Engineering at the Ohio State University after I received my Ph.D. in Computer Science at University of California, Los Angeles. Prior to UCLA, I worked as an Associate/Assistant Researcher at Wireless Networking Group at Microsoft Research Asia. I received a M.Eng and B.Eng in Automation from Tsinghua University, both with highest honors. In the past, I held internships at IBM TJ Watson Research Center, Microsoft Research Redmond and Microsoft Research Asia.

My current research interests are in the broad areas of mobile networking, system and security, with a recent focus on renovating 5G/6G mobile network architecture/protocols/technologies, mobile network analytics, network verification, network security (real attacks and defense), and efficient visual sensing and computing for IoTs (mainly for drones).

Curriculum Vitae

To Purdue Students: There are openings in Research and/or Development in 5G mobile network experimentation and analytics. Currently, my lab is open to independent studies for data-empowered ML, big data visualization, and network analytics. Most of current projects are primarily based on MI-LAB and related to the AIM project (slide). If you want to know more, please email me (drop by is not recommended due to COVID-19).

MI-LAB calling for participants: We continue to call for volunteers and part-time paid positions to conduct driving experiments to measure 5G networks in the US (and even globally). All data collected by you will be released to the whole research community under your consent. The datasets collected by our group (>4TB) in the past three years have been released and visualized here. If you are interested in joining us, please contact

Tutorial on AIM, MobileInsight and beyond

  • This is a brief summary of high-level position talk to the public. It has basic idea, approaches and main results, by skipping all technical details of each research problem under this umbrella project: (pps), (PDF).

  • This is a tutorial of L2/L1 latency analysis enabled by MobileInsight. It was originally used for Hackathon, co-located at ACM SIGCOMM on Aug 25, 2018, and then was reorganized and substantially enhanced for public distribution (step-by-step learning and practice). The used codes and sample logs can be found here. You can find the codes developed by the hackathon team (Quentin, Maryam, Syed and Ensar) at github.

  • This is an 3-hr tutorial on GlobeCom’17 on Dec 8, 2017. It introduces how to step-by-step verify mobile network operations on your phones via MobileInsight. Here is the tutorial slide (pdf) (ppsx). For more up-to-date information, please check our MobileInsight website.
