I am looking for Ph.D. students with strong backgrounds in systems, mobile computing, AR/VR/MR, networking, and applied ML. Please email me your CV and transcript.


I am an associate professor in the Computer Science and Engineering Department at University of Minnesota - Twin Cities. My research interests cover the broad areas of intelligent mobile systems (including 5G), virtual, augmented, and mixed reality (VR/AR/MR) systems, cross-layer system design & analysis, application & transport layer protocols, real-world system measurement, and system security. I obtained my Ph.D. from University of Michigan, and my Bachelor's degree from the ACM Honors Class at Shanghai Jiao Tong University.

I am honored to receive several awards including the AT&T Key Contributor Award (KCA) (2014), NSF CRII Award (2016), Google Faculty Award (2016), ACM CoNEXT Best Paper Award (2016,2018), AT&T VURI Award (2017), NSF CAREER Award (2018), IU Trustees Teaching Award (2018), DASH-IF Excellence Award (2019), Cisco Research Award (2021), and ACM SIGCOMM Best Student Paper Award (2021).

My publication profile can be found at csrankings.org and Google Scholar with total citations of 6200+ (H-Index:36). I am also a co-inventor of 14 U.S. patents.

I prototyped the ARO (mobile Application Resource Optimizer) tool based on our Mobisys 2011 paper. It was productized by AT&T. ARO is open-sourced and widely used in industry. [2017: ARO has been extended into the AT&T Video Optimizer, which adds analysis and best practices for mobile videos.]

My on-going and past research includes:
