Interests: The main interest of my research is in the area of database technology. I am especially interested in XML data management in a database environment. XML has become the ubiquitous and “standard” language for web data/document publication; huge amount of data/document formatted in XML has kept mounting up in a tremendous speed. Effective management and efficient querying of XML data are in great demand. My work in this area focuses on developing new storage models suitable for XML and novel and specialized techniques for efficient XML query processing. My other research interests include data mining, bioinformatics, and the persistence issue of intelligent agents. With data mining, I am interested in a new type of mining approach – applying mobile intelligent mining agents (called intelligent spiders). With bioinformatics, my focus is on rationalizing the drug discovery process, which is traditionally conducted by trial-and-error, via application of proper data mining technologies to the accumulated (gene and protein) sequence data repositories.
