About Me

I’m a final year Ph.D. student at The George Washington University. My research focus is on virtual machines and operating systems, combining a deep understanding of resource management in the cloud and systems security issues with expertise in developing systems with real-world impact. I’ve designed systems that:

  • improve the performance in data-centers by utilizing all of the resources available efficiently, and
  • provide tight and scalable security to the Virtual Machines that run on the cloud.
