Research activities

Research Interests

My primary research interests include information retrieval, web/text mining, advanced database systems, cloud computing, bioinformatics, digital image processing and multimedia, and cooperative work.

Current Projects

I am currently engaged in projects such as applying database and information retrieval methods in Bioinformatics, and one of the principal invesitgators for the CAIM (Context-Aware Image Management) and BioTracer - Search Tools for BioMedical Information

Previous Projects

I have previously been a member of the Cooperating Agents in Global Information (CAGIS) project, working specificly on developing a flexible transactional framework to allow cooperation among software agents as well as human agents, and a member of the Mobile Work and Heterogeneous Systems (MOWAHS) project team, working on database support for mobile and heterogeneous environments.
