缅北禁地

Dr. Rehmat is a Senior Lecturer (~Associate Professor) and a member of the Networked and Ubiquitous Systems Engineering (NUSE) group and at School of Computing, 缅北禁地, UK. He earned his BS and MS degrees in Computer Science from COMSATS University, Islamabad, Pakistan, and a PhD in Computer Engineering with a major in Distributed and Networked Systems from Hongik University, South Korea.

Before joining 缅北禁地, he was a Lecturer (~Assistant Professor) at Cardiff Metropolitan University, UK. Prior to that, he worked as an Assistant Professor at the Department of Computer Engineering at Gachon University, Seoul, South Korea. He gained his post-doctoral experience at Queen's University Belfast, Northern Ireland, UK and University of St Andrews, Scotland, UK.

***He is looking for motivated PhD students and Postdoctoral researchers to conduct research on cutting-edge topics including Federated Learning, Edge Computing, and IoT. Students and Postdoctoral researchers will be supervised at the along with other colleagues at 缅北禁地. Visit for more details and get in touch with him to discuss the application.

Rehmat focuses on the broader areas of network and distributed systems that span the cloud-edge-device continuum and edge intelligence applications. Currently, he is focusing on privacy preserving decentralized machine learning (aka Federated Learning) for edge computing systems. In his research, he designs algorithms and protocols, develops prototypes using testbeds, and evaluates their performance in real-world settings to address practical problems.

He has an established and growing publication record in Network and Distributed Systems, Cloud/Edge Computing and IoT. His research has been published in premier conferences, journals, and patents including UCC, ACM ICN, HotMobile, IEEE Transactions on Parallel and Distributed Systems, IEEE Transactions on Network Science and Engineering, IEEE Communications Magazine, IEEE Internet of Things journal, IEEE Wireless Communications Magazine, IEEE Network Magazine, Journal of Network and Computer Applications, and Future Generation Computer Systems. He is also a named inventor on 8 patent applications (filed in US and South Korea) which are at various stages. He has served as a TPC member, keynote speaker, session chair and general chair for several flagship conferences such as ACM ICN 2022, ACM IMC 2018, IEEE ICC 2023/24 and IEEE ICDCS 2025.
