I currently work as a Senior Protection Engineer at Barkly, an endpoint security company. My primary focus is to develop systems that protect our customers against modern-day attacks.
I have a Ph.D. from The George Washington University under the advisement of Dr. Timothy wood. My area of focus was Performance, Utilization and Security of Cloud Systems.
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:
The systems I have designed has been widely adopted and used.
