I was born in Jaffna, Sri Lanka and left to Norway in 1985 due to civil war. I received the Siv.Ing (MSc)
and Dr.Ing. (PhD) degrees both in signal processing from the Signal Processing Group,
Department of Electronic Systems,
Norwegian University of Science and Technology (NTNU), Trondheim, Norway in 1993 and 1998, respectively. I did my Master thesis at the University of California in Santa Barbara, USA under the supervision of Prof. Sanjit K. Mitra. My PhD supervisor was Prof. Tor A. Ramstad at NTNU in Trondheim, Norway.
From 1998 to 2002, I was employed as a Research Engineer developing video streaming solutions to mobile handheld devices at Fast Search & Transfer ASA, Oslo, Norway. Fast, which was a startup compancy in 1998, was acquired by Microsoft Inc in 2008. Since 2002, I have been with the Intervention Center,
Oslo University Hospital - Rikshospitalet, Oslo, Norway as a Sr. Research Scientist and Founder and Head of the Biomedical Sensor Network Research Group. I was appointed as a Professor of Signal Processing in Medical Technology at NTNU in 2006.
I was Professor by courtesy at the Frontier Institute, Nagoya Institute of Technology, Nagoya, Japan during the academic year 2016-2017.
My research interests include medical signal and image processing, wireless biomedical sensor networks for short range sensing, imaging, localization and communication, and multimedia patient record systems. Lately I have been involved in nano scale communication networks - molecular communications using biology and nanotechnology for intra-body applications like minimally invasive diagnosis, monitoring, and drug delivery.
