The group is headed by Prof. Tharmalingam Ratnarajah (A’96-M’05-SM’05), who is currently working as a Professor in Digital Communications and Signal Processing with the Institute for Digital Communications, University of Edinburgh, Edinburgh, UK. He was the Head of the Institute for Digital Communications from 2016 to 2018. His research interests include signal processing and information-theoretic aspects of beyond 5G cellular networks, full-duplex radio, mmWave communications, random matrix theory, big data analytics and machine learning for wireless networks, statistical and array signal processing, physical-layer secrecy and interference alignment. He has published over 460 Peer-reviewed papers in these areas and holds four US patents. He was the coordinator of the European Union (EU) projects HARP (4.6M€) in the area of highly distributed MIMO and ADEL (3.7M€) in the area of licensed shared access. He was also the coordinator of the European Union Future and Emerging Technologies project CROWN (3.4M€) in the area of cognitive radio networks and HIATUS (3.6M€) in the area of interference alignment. Prof Ratnarajah was an associate editor of IEEE Transactions on Signal Processing, 2015-2017, and Technical co-chair of the 17th IEEE International Workshop on Signal Processing Advances in Wireless Communications, Edinburgh, UK, 3-6, July 2016. Prof. Ratnarajah is a Fellow of the Higher Education Academy (FHEA). He has supervised 18 PhD students and 24 post-doctoral research fellows and raised $11.0+ million (USD) of research funding.

​Dr Ratnarajah was born and educated up to the secondary school level in Sri Lanka. He left Sri Lanka in 1989 to pursue his higher education (BEng (Hons), MSc and PhD) and has worked in various places in the United Kingdom and Canada. He is a naturalized citizen of Canada since 2000 and a naturalized citizen of the United Kingdom since 2010.
