Hello, My name is Hengchang Liu. Hengchang is my first name, where "Heng" means everlasting and "Chang" means prosperous in Chinese. Liu is my last name, which is probably the most popular surname in China. I love this name a lot!

  I will be a summer intern at Microsoft Research Asia from May to August, 2008.

Biographical Sketch

I joined the University of Virginia in August 2006, under the direction of Professor John A. Stankovic, before that I received my B.S. in Maths and M.E in Computer Science at the Special Class for Gifted Young in USTC in July 2003 and 2006. In addition, I was once an intern in the Wireless and Networking Group at Microsoft Research Asia in 2004.

Recent Research Project

    December 2007 - Present: Leading the FishNet Project collaborated with environmental scientists. Our goal is to track fish location and monitor chemical pollution.

    December 2006 - Present: A major member in the LUSTER Environmental Project. I am responsible for the deployment-time validation (Seemote/SeeDTV).

    August 2006 - Present: Leading a small DTN research group. We have focused on the buffer management for QOS-Heterogeneous surveillance sensor networks.

    August 2006 - December 2006: A member in the AlarmNet Medical Project. I was responsible for the design and implementation of Dust Sensor Driver.
