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), Trustees Teaching Award (2018), DASH-IF Excellence Award (2019), Cisco Research Award (2021), ACM SIGCOMM Best Student Paper Award (2021), Google Research Scholar Award (2022), ACM MobiCom Best Community Contribution (2022), and AI 2000 Top-100 Scholar in Networking (2022,2023).

My publication profile can be found at and Google Scholar with total citations of 7,800+ (H-Index:43). I am also a co-inventor of 37 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. [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:
