My research interests broadly span networking, systems, and their intersection. My main research objective is to make networked systems run more efficiently! Therefore, my work often addresses a variety of challenges at application and network levels. I have been recently working in various areas such as Multicast Systems, Datacenter Networking, Multimedia Systems, and Cloud Gaming. I previously worked in other areas such as 3D video streaming and GPU virtualization. I am currently affiliated with the Network and Multimedia Systems Lab at SFU.

I received my PhD from the School of Computing Science at SFU. Before starting my PhD, I worked as a Research Assistant at Qatar Computing Research Institute in the Distributed Systems group. I also worked as a Software Development Engineer at Mentor Graphics (later acquired by Siemens). I got my BSc degree in Computer Engineering from Cairo University, where my graduation thesis was about designing an efficient GPU-accelerated data mining system.

Research Highlights (Details)

...
Multicast Forwarding and Routing

My research addresses the scalability and efficiency challenges in multicast systems to (i) support various routing requirements of ISPs such as traffic engineering and service chaining, and (ii) forward packets of large numbers of concurrent multicast sessions. My main contribution is designing systems and algorithms to reduce or even eliminate the required state to be maintained at network switches.

...
Data Center Networking

The current focus of my research is to design various networking primitives to efficiently manage the network resources. My work also focuses on the multi-tenancy aspects of cloud datacenters.

...
Multimedia Systems

My recent work focused on two aspects of multimedia systems (i) the adaptive streaming of multiview videos, and (ii) the traffic engineering and content placement of multimedia content

...
Cloud Gaming

This research focuses on reduce the bandwidth usage of cloud gaming while achieving a high perceived quality. We collaborate with researchers from AMD and University of Ottawa in designing our systems.
