ABOUT ME

I am a PhD candidate in Computer Science at University of California, Santa Cruz working with Professor Wang-Chiew Tan. I am interested in all aspects of data management, with emphasis on information integration and data provenance. I will be graduating in 2008.

At UC Santa Cruz, I am involved with the Database Research Group and the eWomen - Women in Engineering Group.

I received my BS in Computer Engineering from Politehnica University of Bucharest in 2003. While an undergrad, I worked for several Romanian IT companies, where I was involved in developing a wide range of applications - from web-based content management systems to computer graphics tools and online games.

PROJECTS

Schema Integration
I have spent two great summers as an intern in IBM Almaden, where I have been involved in the design and implementation of a schema integration framework on top of the Clio schema mapping system.

SPIDER - a Schema mapPIngs DEbuggeR
I have designed non-intrusive, data-driven techniques for debugging schema mappings that employ (test) data to drive the process of exploring, understanding and refining a schema mapping. I have implemented these techniques in SPIDER, a prototype debugger for schema mappings. More details about this work can be found here.

DBNotes - a relational DataBase anNOTation managEment System
I have been involved in the design and development of DBNotes, an annotation management system for relational data. Among others, I have designed and implemented DBNotes' mechanism for tracing the provenance and flow of data through multiple transformation steps, expressed as SQL queries. More details about this work can be found here.

MUSE - a System for Designing Schema Mappings by Example
Muse is a system that complements SPIDER by providing techniques for designing mappings based on data examples. I have designed MUSE's algorithm for guiding a user in selecting the correct interpretation of a semantically ambiguous mapping.

Computing the Core in Data Exchange
As part of this project, I designed a new algorithm that computes the core in special important data exchange settings by means of SQL queries only, thus leveraging existing database technology.
