About me

I am Ahmed M. A. Sayed, a Senior Lecturer (Associate Professor) and the Director of the MSC Big Data Science Programme at School of EECS, Queen Mary University of London, UK. I lead SAYED Systems Group where we strive to design and build Scalable Adaptive Yet Efficient Distributed systems of the Future. I am the Principal Investigator of a grant funded by UKRI-EPSRC New Investigator Award for Project KUber in partnership with major industrial players (i.e., Nokia Bell Labs, Samsung AI, IBM Research). I have a PhD in Computer Science and Engineering from the Hong Kong University of Science and Technology (HKUST) advised by Brahim Bensaou. I held the positions of Senior Researcher at Future Networks Lab, Huawei Research, Hong Kong and Research Scientist at SANDS Lab, KAUST, Saudi Arabia working with Marco Canini. My early research involved optimizing networked systems to improve the performance of applications in both wireless and data-center networks and proposing efficient and practical systems for distributed machine learning. My current research focus involves designing and prototyping Networked and Distributed Systems of the Future. In particular, I am interested in developing methods and techniques to enhance the performance of networked and distributed systems. I am currently focusing on developing scalable and efficient systems supporting distributed machine Learning (esp., distributed privacy-preserving ML aka. Federated Learning). I also organise and teach ECS640U/765P Big Data Processing (UG/PG module) and teach ECS637U/757P Digital Media and Social Networks (UG/PG module).
