Hey, I'm Sunny Raj

I am a final year Ph.D. student at The George Washington University advised by Dr. Timothy wood. I love working on complex technical problems. I have a strong understanding of Operating Systems, how the software interacts with the hardware, which enables me to develop applications that are extremely efficient.

Systems researcher and programmer. Language enthusiast. Avid and a quick learner. I'm quick on my feet when it comes to learning and implementing new technology. Love researching about systems, looking into the unknown and pushing the envelope.

More formally, 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.
