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), long

To Purdue Students: There are openings in Research and/or Development in 5G mobile network experimentation and analytics. Please read my current research and the note.

Hiring: I am always looking for strongly-motivated, talented Ph.D, MS and undergraduate students who are devoted to research excellence or high-quality hacking/development in mobile networking, security and systems. Please read the note and then contact me.

Open to postdocs, professional staffs: I am looking for one postdoc for 5G network research (requirement: networking, AI or formal methods). Please send me your CV and a short research statement while contacting me. I am also looking for one professional staff to develop and manage a data-driven mobile networking testbed (requirement: web service, database, cloud service, mobile networking protocols, big data mining and machine learning).

Talk on AIM (CAREER)

  • 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).

  • A variety of richly extended verions presented at recent visits to Qualcomm, MIT, UIUC, UT Austin, Rice, MSU, IUPUI, Purdue, and Notre Dame.

Tutorial on MobileInsight

  • 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.
