I am a Ph.D. candidate in the Indiana University Department of Computer Science, working as a RA in Extreme Lab. My advisor is Prof. Dennis Gannon, meanwhile I cooperate a lot with Prof. Kenneth Chiu of SUNY binghamton.  My CV is available here  and my research statement is here.

 

 

RESEARCH INTEREST

 

I have been motivated to improve the performance of the Web Service and XML processing. The approaches I have explored includes Schema specific XML compiler , Streaming XML message processing and Binary XML encoding scheme. Recently, I have been focusing on how to leverage the Multicore resource to accelerate the XML and SOA processing. One of my current approaches is the Parallel XML Processing, including Parallel XML Parsing and Parallel XPath Query,  Also I am investigating the BPEL (Business Processing Execution Language) workflow-engine implementation on the multi-core CPUs for the better service scalability.

Generally speaking, I am very interested in these research topics in the fields of  Concurrent & Parallel programming, Grid & Distributed system, Operating system kernel, Virtual machine,  Programming language.
