My research interests are in the areas of parallel and distributed systems, high performance computing, grid computing, game theory, science and engineering applications. Specifically, my research is on developing methodology for concurrent processing on various computer systems. The main contribution of my current research consists of deriving new job allocation and load balancing schemes for distributed and grid systems based on game theory which provide both good performance and scalability.
