Rehmat Ullah, Ph.D.

Post-Doctoral Research Fellow at School of Electronics, Electrical Engineering and Computer Science, Queen's University Belfast, UK.

In a nutshell

I earned my B.S. and M.S. degrees in Computer Science from COMSATS University Islamabad, Pakistan, in 2013 and 2016, respectively, and the Ph.D. degree in Electronics and Computer Engineering from Hongik University, South Korea, in February 2020. Currently, I am a Post-Doctoral Research Fellow at Queen's University Belfast, UK working with Dr. Blesson Varghese at the Edge Computing Hub in school of Electronics, Electrical Engineering and Computer Science. My main tasks at the Edge Computing Hub include: (i) conducting research in tackling system-oriented challenges of Edge or Fog computing, (ii) assisting in the development of research proposals, (iii) contributing to the supervision of PhD candidates, (iv) coordinating and liaising with other members of the research group and the Rakuten Mobile team in Japan over work progress, and (v) planning and delivering the research activity to meet relevant objectives of the Edge Computing Hub and performance indicators set by the funder. Prior to joining Queen’s, I was an Assistant Professor with the Department of Computer Engineering at Gachon University, Seongnam, South Korea.
My research focuses on the broader area of network and distributed systems particularly the development of architectures, algorithms, and protocols for emerging paradigms, such as edge/fog computing, Internet of Things (IoT), information centric networking/named data networking (ICN/NDN), and 5G evolution and beyond. This includes the design, measurement studies, prototyping, testbed development, and performance evaluations.
