Academic Experience
Research Assistant, Spring 2002 - present
Worcester Polytechnic Institute, Worcester, MA.
Research flexible loading XML data into object-relational database, query rewriting from XML query into
SQLs, order sensitive query processing, and update propagation. The main application of this work is
the flexible and powerful XML document management. Built and maintained a software system called
"Rainbow" that demonstrates the findings.
Research Assistant, Spring 2000 - Fall 2001
Worcester Polytechnic Institute, Worcester, MA.
Research querying XML data by reusing relational technology and related technologies, e.g., importing
and exporting XML documents and sychronizing XML data updates using related DB engines. Built
and maintained a software system called "Clock" that demonstrates the findings. [Funded by Verizon
Laboratories Incorporated.]
Research Assistant, Spring 1998 - Spring 2000
Worcester Polytechnic Institute, Worcester, MA.
Researched into data warehouses in general and data warehouse evolution in particular under the umbrella
of the EVE project (Evolvable View Environment). The main application of this work is the support of
changing information sources on the WWW into views that combine information from several sources and
their maintenance under changes. Built and maintained a software system that demonstrates the findings.
[Funded by NSF grant.]
