Since Aug 2017, I am an Assistant 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 in 2013. Prior to UCLA, I worked as an Associate/Assistant Research at Wireless Networking Group at Microsoft Research Asia. I received a M.Eng and B.Eng in Automation from Tsinghua University in 2005 and 2002, 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 innovating 5G/4G mobile network architecture/protocol/technologies for demanding apps (performance and reliability), mobile network data analytics and inference, network verification via formal methods, network security (real threats and defense), and mobile/IoT communication and sensing techniques over new wireless (e.g, light or sound).

Curriculum Vitae: short (2-page)

What is NEW?

Call for participants: MI-LAB is calling for participants (volunteers and paid positions) to conduct driving experiments across the US and even globally. We plan to build a MAP to profile our 5G and 4G access. All data collected through these experiments will be released to the whole research community under your consent. The datasets collected by our group in the past two years have been released and visualized here or there (this is a direct link). If you are interested in joining us, please contact me and/or

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 schedule an appointment (drop by is OK but not preferred).

PhD Hiring: I am always looking for strongly self-motivated Ph.D students who are devoted to research excellence or high-quality hacking/development in mobile networking, security and systems. If you are interested in working with me, please read the note and then contact me.

Open to postdocs: I am looking for one postdoc for 5G network research (requirements: networking, explainable AI, approximation/formal methods). Please send me your CV and a short research statement while contacting me.

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.
