RESEARCH EXPERIENCE

• May 2005 - Present. CAPE System.
  I am a member of the CAPE Group, a Constraint-exploiting Adaptive Stream Processing Engine. Collaborating with other students in WPI database research group, I am working on multiple continuous query processing and optimization techniques with window constraints.

• May 2003 - Present. Rainbow System.
  I am a core member of the Rainbow Group, an algebraic XML query processing platform. Collaborating with other students in WPI database research group, I am working on algebraic XQuery optimization techniques in native XQuery processing, multiple query optimization using views and XML publication and storage. In particular, I explored and designed XQuery decorrelation for nested XQuery FLWOR with ordered semantics. I built part of the demonstrated Rainbow system at SIGMOD'03.

• May 2001 - May 2003. XCache System.
  XCache system is a semantic caching for answering XQuery using views. Collaborating with other student, I built part of the system shown in the demonstration session of SIGMOD'02. In particular, I proposed the fine replacement strategies suitable for XQuery containment matching. I also conducted experiments for performance analysis for the replacement model. Besides the demonstration we also have papers published on this in WIDM'02 and DKE journal.

• Feb. 1999 - Jul. 2000. Prefetching and Caching for Proxy Server.
  This project aims to build software Proxy Server with function of dynamic prefetching and cache. We proposed several strategies based on user access pattern, network traffic measurement and predications. I proposed part of system modeling, designed and implemented of the proxy server using C/C++.
