Curriculum Vitae
Resume

I am currently a Ph.D. candidate in the Computer Science Department at the University of Southern California. I also work in the Semantic Information Research Laboratory, under the direction of my advisor, Dr. Dennis McLeod. My interest lies on ontology-based Data Mining, especially clustering association rules using ontologies with market basket data.
