Clustering Techniques
I am interested in developing clustering algorithms for data sets with categorical attributes. I have devised “LIMBO”, a scalable algorithm that clusters both tuples of categorical data and the values within attributes of categorical data.

Schema Discovery
I am studying the use of clustering techniques in decomposing relational tables. More precisely, I am currently extending “Limbo” so that it can find regions of homogeneous content in the data.

Data Warehousing
In the past, I have conducted research on multidimensional data modeling. I have also worked on recasting Program Reverse Engineering to On-Line Analytical Processing.
