Research Interests

• Performance modeling and simulation of large scale distributed software systems
  Here I attempt to come up with simple yet efficient models that can predict
  various different situations that occur in the real world. My focus is on
  combining profile based techniques with analytical methods to come up with accurate models.


• Optimal resource allocation of distributed component based systems
  I am working on developing heuristic algorithms which can make use of system
  models to compute static allocation of resources to applications such that
  overall cost of deployment is minimized.
