WORKING EXPERIENCE

*MTS, VMware, Palo Alto, CA, 10/2008 to present
--Worked in VMware Studio team; VMware Studio is a tool to automate the creation/update of Virtual Appliance (virtual machines + OS + application software user configurations);
--Implemented a feature which updates existing appliance as user requests (mainly using Perl, Bash Shell script and Python). It receives positive feedback and becomes the main feature of next two releases;
--Implemented CIM providers for package update service and package creation service (mainly using c++ in Linux);
--Organized the existing system using object oriented design, which makes Studio more extensible and more maintainable;
--Wrote unit tests and solved different bugs

*Intern, Reva Systems, Chelmsford, MA, 05/2007 to 08/2007
--Designed an algorithm to detect moving RFID tags, which achieves a correctness of 99%.;
--Implemented an event-replay tool which reads log files then constructs messages and feed them to Reva's System (using c++ in Linux). Reva standardized this as a test tool for code check-in.

*Software Engineer, ZTE Corp., Shenzhen, China, 07/2002 to 09/2005
--Worked in CDMA Protocol team, which is responsible for implementing L2/L3 of CDMA protocol;
--Developed a module for call establishment and handoff (30,000+ lines of c code). It does: interact with five peer modules, use hash table to find existing users, use linked lists to manage dynamic allocation and release of index resources, maintain eight different states/sub-states according to CDMA protocol, and handle all exceptions. This module runs stably in commercial environment;
--Designed a processor selection algorithm for our multi-processor system and applied a patent in 2004;
--Implemented state synchronization between active system and backup system. By this design, active processor can switch to backup system without interrupting service.


EDUCATION
--Master of Science in Computer Science, 2008
From Northeastern University, Boston, MA
--Master of Science in Electrical Engineering, 2002
From Huazhong University of Science & Technology, Wuhan, China
--Bachelor of Science in Electrical Engineering from Honor Program, 1999
From Huazhong University of Science & Technology, Wuhan, China


SELECTED SCHOOL PROJECTS      	                                		                                                      

*SPREAD project
--Proposed a new way, called “protocol/mechanism jumping”, to increase the robustness of wireless network against jamming attack, and simulated its performance based on 802.11. 
--This work led to a paper in 2007.

*Covert Channel Analysis in GSM System
--Proposed a new way for two synchronized nodes to communicate by using GSM system without being detected: in one time slot the sender sends single information bit by accessing GSM system zero/one time, and the receiver reads the bit by observing response broadcasted by GSM system;
--Analyzed the channel capacity of this covert channel, based on the number of GSM users.


*PUBLICATIONS AND PATENT
--Paper: SPREAD: Foiling Smart Jammers using Multi-layer Agility, in proceedings of IEEE Infocom 07, mini-symposium.
--Patent: A CPU Selection Algorithm for Call Processing System With Multi-CPU, China Application Number: 200410026833.1, Issue Date: 13/04/2004.
--Paper: A BP Algorithm with Self-adapting Slope Output Function, Journal of Huazhong Univ. of Science and Technology, Nov. 2001.
--Paper: Two-value Segmentation of Complex Color Image and Preliminary Dealing, Journal of Huazhong Univ. of Science and Technology, Nov. 2001.
