Research interests

Signal Processing - intelligent information infrastructures for wireless communications and radar technology, parasitic antenna technology and analogue beamforming and precoding techniques,  adaptive, cognitive (intelligent) and statistical signal processing techniques in a range of applications including Radar, Lidar, Sonar and RF networks, Network Coding, Cognitive Radio, MIMO signal processing, satellite communications and underwater communications.   


Prof. Mathini Sellathurai is currently a Full Professor in Signal Processing with the Heriot-Watt University, Edinburgh, U.K and leading research in adaptive, cognitive and statistical signal processing techniques in a range of applications including Radar, Lidar, Sonar and RF networks, Network Coding, Cognitive Radio, MIMO signal processing, satellite communications and underwater communications.   She has been active in the area of signal processing research for the past 15 years and has a strong international track record in multiple-input, multiple-output (MIMO) signal processing with applications in radar and wireless communications research.  

Prof. Sellathurai has 5 years of industrial research experience. She held positions with Bell-Laboratories, New Jersey, USA, as a visiting researcher (2000); and with the Canadian (Government) Communications Research Centre, Ottawa Canada as a Senior Research Scientist (2001-2004). Since 2004 August, she has been with academiaShe also holds an honorary Adjunct/Associate Professorship at McMaster University, Ontario, Canada, and an Associate Editorship for the IEEE Transactions on Signal Processing between 2009 -2013. Presently serving as an IEEE SPCOM Technical Committee. 

Prof. Sellathurai has published over 120 peer reviewed papers in leading international journals and IEEE conferences; given invited talks and written several book chapters as well as a research monograph as a lead author.  The significance of her accomplishments is recognized through international awards, including an IEEE Communication Society Fred W. Ellersick Best Paper Award in 2005, Industry Canada Public Service Awards for contributions in science and technology in 2005 and awards for contributions to technology Transfer to industries in 2004.  Dr. Sellathurai was the recipient of the Natural Sciences and Engineering Research Council of Canada’s doctoral award for her Ph.D. dissertation

 We have been presently funded by EPSRC and DSTL(http://www.see.ed.ac.uk/drupal/udrc/people/edinburgh-consortium/dr-mathini-sellathurai). The research group  is also involved in European Union Frame Work 7  projects  Cognitive radio oriented wireless networks (http://www.fp7-crown.eu/keymembers.html) and interference alignment (http://www.fp7-hiatus.eu/index.php/keymembers.html).

 In the past, she was  involved in signal processing for defense research in the first phase of UDRC programme for work on Forward Looking RADAR and OFDM signal recognition/classification.  The group has also been funded by industries QinetiQ and Wireless Fiber Systems to work on MIMO RADAR and underwater communications;  EPSRC under EP/D07827X/1 for advanced signal processing techniques for multi-user multiple-input multiple-output broadband wireless communications; MIMO-RADAR and waveform agility to improve low elevation target detection (also partially supported by QinetiQ, Portsmouth); EP/G026092/1 for Bridging the gap between design and implementation of soft-detectors for Turbo-MIMO wireless systems and EP/H012257/1 for Signal Processing Techniques to Reduce the Clutter Competition in Forward Looking Radar.

Prof. Sellathurai was an organizer for the IEEE International Workshop on Cognitive Wireless Systems, IIT Delhi, India, 2009, 2010 and 2013, and the IEEE WCNC 2013 - WORKSHOP - New Advances for Physical Layer Network Coding, 2013, Shanghai, China.. She has been a Technical Program Committee member for the IEEE International Conference of Communications from 2004 to 2012 and was a National publicity Champion for ICC 2013, Budapest. She is also a peer review college member of Engineering and Physical Sciences Research Council, UK.
