Jie Liu

Principal Researcher and Research Manager


I am a Principal Researcher and a Research Manager at Microsoft Research-NExT, leading Project Vesta, MSR’s Venture on Embedded Sensing Technologies and Applications (previously known as the Sensing and Energy Research Group — SERG). My group conducts fundamental and systems research on sensing and energy-efficient computing.

My personal research interests root in understanding and managing the physical properties of computing. Examples include timing, location, energy, and the awareness of and impact on the physical world. I worked on actor-oriented modeling, simulation, & programming models, low power and networked sensing, system resource management & control, mobile context extraction & management, and novel mobile & cloud applications. My recent projects range from sensor networks, wearable devices, mobile computing, to data centers.

Before joining MSR in May 2004, I was a researcher at Palo Alto Research Center (formerly Xerox PARC). Since 2008, I also hold an adjunct professorship (Foreign PhD Advisor) at Harbin Institute of Technology, China. I got my Ph.D. degree from EECS, UC Berkeley in 2001; got my Master (1996) and Bachelor (1993) degrees from Department of Automation, Tsinghua University, Beijing, China.


Project CLEO

Established: January 18, 2013

The goal of project CLEO is to develop devices and services to encourage and enable participatory sensing and citizen scientists. A core technology developed in the project is to make location sensing energy efficient, so devices can be small and light, sample more frequently, and of low cost. The approach is called Cloud-Offloaded GPS (or CO-GPS). News: Mobile Location Sensing Tutorial at ACM MobiSys 2013, June 25th, 2013, Taipei. Jie Liu gave a keynote address at…

LiveSynergy – Bridging the Gap between Virtual and Physical Worlds

Established: November 15, 2011

LiveSynergy is a novel magnetic-based wireless proximity detection platform, with accuracy and consistency better than existing solutions such as BLE, WiFi, ZigBee, and long-range RFID. Building on top of this platform, we provide cloud-based APIs that enable real-time and rich interactions between humans and their physical environment. LiveSynergy enables a range of indoor applications such as location-based targeted advertising and presence detection.   News Jan. 2012: Our LiveSynergy paper "Design and Evaluation of a Wireless Magnetic-based…

Joulemeter: Computational Energy Measurement and Optimization

Established: February 23, 2010

The public release of Joulemeter is deprecated. We apologize for any inconvenience.The Joulemeter project provides a modeling tool to measure the energy usage of virtual machines (VMs), servers, desktops, laptops, and even individual software applications running on a computer. The visibility provided by Joulemeter is being used to improve power provisioning costs for data centers, virtualized power budgeting, desktop energy optimizations, and mobile battery management. Note: Joulemeter is no longer available for public download. Similar…
