RESEARCH INTEREST AND PUBLICATIONS

Presently I am working in the areas of Grid Computing, Parallel Computing and Cloud Computing. In Grid Computing we work in several areas including design of broker for replica selection problem, design of efficient authorization in Grids etc. In Parallel Computing the work is in the areas of Investigating issues in Distributed Shared Memory (DSM), Parallel Compilers, and Scheduling on multi core computers. In cloud computing we are working on design of P2P architecture, brokerage strategies for user's QoS parameters and design issues of Brokerage Manager.
