RESEARCH EXPERIENCE

Research Assistant, UVA Real-time System Lab 2005-present

Designed multi-channel algorithms and network protocols to provide reliable and real -time wireless

communication. One of protocols reduced end-to-end transmission data loss by 15% and decreased latency by

15%.

Designed and built a new MAC protocol which uses a novel coding based technique to recover packets after

collision. The protocol improved transmission efficiency of sensor networks by 20%.

Designed and built large wireless sensor systems for environmental monitoring of islands off the shore of

Virginia. The system is funded by U.S. Long-term Ecological Research Network.

http://www.cs.virginia.edu/~yw5s/luster/

Designed and built a novel run time assurance framework for Wireless Sensor Systems, which can

automatically generate codes according to user requirements, and self-testing system functionality at the

runtime.

Research Assistant, Algorithm and High Performance Computing Group 2002-2005

Designed various optimization algorithms to solve graph theory problems.

Designed and built energy-efficient routing and multicast protocols in Wireless Mesh Networks.

WORK EXPERIENCE

YAHOO! INC SUNNYVALE, CA

Senior System Engineer in Sponsored Search Team Aug 2010 ~ present

Designed and implemented scalable UDP software (using Perl) to manage communication between Ads search

frontend and backend servers, which improves Ads Search Performance by balancing load among backend

servers, and provides fault-tolerant techniques to deal with network failures and server crashes.

The software was launched to productions that servers billions of d ollars a year for Yahoo! Ads search. It

allowed Yahoo save potentially $350,000 by substituting expensive CISCO hardware currently used for the

similar functionality.
