Biography

Dr. Susanto Rahardja received his Ph.D. degree from the Nanyang Technological University (NTU, Singapore) in Electrical & Electronic Engineering. In 1996, he joined the Centre for Signal Processing at NTU as a research engineer and was appointed Assistant Director of the Centre in 2001. Dr Rahardja was the Director of Media Division at the Institute for Infocomm Research (I²R) from 2002 to 2007, where he led 150 full-time researchers in a broad range of media related research that cover areas in Signal Processing (audio coding, video/image processing), Media Analysis (text/speech, image, video), Media Security (biometrics, computer vision and surveillance) and Sensor Networks. His research interests are in Audio/Video Signal Processing, Spread Spectrum and Multi-user Detection Techniques for CDMA Applications, Digital Signal Processing Algorithms and Implementations, Logic Synthesis, of which he has more than 200 publications in internationally refereed journals and conferences. Currently, he is Principal Scientist, Director of Personal 3D Entertainment System program and Head of Signal processing Department at I²R. He is also a Program Director of Science & Engineering Research Council of A*STAR.

Dr Rahardja is also a Senior Member of the Institute of Electrical and Electronics Engineers (IEEE). He was the recipient of the IEE Hartree Premium Award for the best journal paper published in IEE Proceedings in 2002. This is an annual award by the Council of IEE, which recognizes outstanding papers published in IEE Proceedings on Computers and Digital Techniques. In 2003, Dr Rahardja received the prestigious Tan Kah Kee Young Inventors’ Gold award in the Open Category, for his contributions to scalable to lossless audio compression technology.

Since 2002, Dr Rahardja actively participates in the international ISO/IEC JTC1/SC29/WG11 (Moving Picture Expert Group, or MPEG) where he contributed to the development of MPEG-4 Scalable to Lossless System (SLS) in which the technology was adopted as Reference Model 0 by MPEG in July 2003. This was subsequently published as an international standard in June 2006 (ISO/IEC 14496-3:2005/Amd.3:2006). At the same time, he led the team to develop an adaptive predictor technology for the audio lossless codec which was incorporated in the MPEG-4 Audio Lossless System (ALS) under the high performance profile (ISO/IEC 14496-3:2005/Amd.2:2006). In recognition of his significant contributions to the national standardization program, Dr Rahardja was awarded the Standards Council Merit Award by SPRING Singapore in 2006. In addition, for leadership and technical contribution to advancement of digital audio signal processing and its adoption to the MPEG, he was awarded the National Technology Award in 2007.

Dr Rahardja has served in several boards, advisory and technical committees in various IEEE and SPIE related professional activities in the areas of multimedia. He is elected members of the Technical Committee of the Visual Signal Processing and Communications, Circuits and Systems for Communications and Multimedia Systems and Applications of the IEEE Circuits & Systems Society. He is currently serving as Associate Editors for IEEE Transactions on Audio, Speech and Language Processing, the Journal of Visual Communication and Image Representation and IEEE Transactions on Multimedia. He served as the Conference Chair of Multimedia Systems and Applications at SPIE OpticsEast Symposium from 2006 to 2007 as well as Symposium Co-chair of the IEEE International Symposium on Multiple-Valued logic in 2006. He was also the Industry and Government Advisor of 1st ACM SIGGRAPHASIA 2008 and the General Chair of 7th ACM SIGGRAPH VRCAI 2008.
