The main theme of my research is integration. This can be integration of data from different sources, integration of services, integration of applications and lastly data from different devices (IoT). The main topics are
information integration, service computing, Internet of Things, health informatics, scientific
workflows, databases, and agent technologies.

Other research interests
My secondary research goal is to provide technique and model for accurate and rapid retrieval of multimedia data (MDB).
Information processing has shifted from textual data to include still images,
video and audio data. This requires substantial changes
in the way we build and manage databases.
The list of issues that I am investigating are:
- Reasoning and modelling of multimedia data
- Unified indexing scheme to support fast retrieval of
of multimedia data
- Querying moving objects in multimedia database
