Research interests

The main theme of my research is knowledge discovery via AI and database technologies. This can be intelligent integration of data from different sources for efficient provisioning of services and scalable integration of sensor data from different devices (IoT) for health monitoring. The main topics center around internet of things, smart health, scientific workflows, databases, service computing, software engineering and agent technologies.

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
