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 access technologies, AI for networks, 5G/IoT security, mobile edge computing (mainly for drones and robots).

Curriculum Vitae

What is NEW?

PhD Hiring (2023 - 2024): I am looking for self-motivated Ph.D students who are devoted to research excellence or high-quality system building/hacking in mobile networking, security and systems. In the coming years, I am hiring students particularly interested in building private 5G networks, hacking 5G security and developing physical AI on robots. If you are interested in working with me, please read the note and then contact me.

To students at Purdue: There are openings to Research and/or Development in my lab, through independent studies (undergrad, MS and PhD) and thesis options (MS and PhD). There are several ongoing projects in AI and security which are calling for your participation. I would like you to have a quick look at my active research and recent publications first. If you want to know more, please email me (drop by is not recommended).

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.
