Epps and E. Ambikairajah (Australia) Room: Maximillian Room Genomic signal processing research has seen considerable growth in recent years with the advent of the IEEE Workshop on Genomic Signal Processing and Statistics, now an annual conference. Sequence analysis has also attracted increasing attention over the past few years, with applications including sequence similarity, gene/exon detection, sequence characterization using periodicity measures, and tandem repeat detection. Signal

processing and pattern recognition methods have considerable potential to help biologists uncover structure in DNA and provide tools to assist in the discovery of new drugs.

This tutorial aims to equip signal processing and pattern recognition researchers with a basic understanding of how signal processing techniques can be applied to genomic sequence data, fundamental issues concerning the numerical representation and frequency-domain interpretation of symbolic sequences, evaluation methods, and an overview of current research in the area and challenges ahead. Familiarity with concepts from undergraduate signal processing courses should be sufficient background knowledge for participants of this tutorial. Dr. Epps received the BE and PhD degrees from the University of New South Wales, Australia, in 1997 and 2001, respectively. After an appointment as a Postdoctoral Fellow at the University of New South Wales, he worked on speech recognition and language processing research first as a Research Engineer at Motorola Labs and then as a Senior Researcher and Project Leader at National ICT Australia. He joined the UNSW School of Electrical and Telecommunications as a Senior Lecturer in 2007, and is

currently on leave as a Visiting Scientist with the Institute for Infocomms Research (I2R), Singapore. He has authored or co-authored approximately seventy publications, including more than ten in the area of genomic signal processing (including signal processing-oriented conferences such as ICASSP and GENSIPS and pattern recognition conferences such as the ICPR Workshop on Pattern Recognition in Bioinformatics). He has served as a reviewer for several journals including the EURASIP Journal on Bioinformatics and Systems Biology, and as a programme committee member for numerous conferences, including GENSIPS. Associate Professor Ambikairajah received his PhD degree from Keele University, UK. He was appointed Head of Electronic Engineering and later Dean of Engineering at the Athlone Institute of Technology in the Republic of Ireland. He joined the University of New South Wales, Australia in 1999 where he is currently the Deputy Head of School and the Director of Academic Studies in the School of Electrical Engineering and Telecommunications. He received the Vice-Chancellor's Award for Teaching Excellence in April 2004 for his innovative use of educational technology. He has authored and co-authored approximately 150 conference and

15

journal papers, and is also a regular reviewer for several IEEE, IEE and other journals and conferences. Together with Dr. Epps, he has received two research grants in genomic signal processing, and has supervised one Postdoctoral Fellow, one Research Assistant and one PhD student in this area. A/Prof Ambikairajah is currently a Fellow and a Chartered Engineer of IET (UK) and IEAust (Australia), and a member of the IEEE. 15:00 – 15:30 COFFEE BREAK Location: Diesner Foyer 15:30 - TUTORIAL PRESENTATION CONTINUED ******************************** IASTED would like to thank you for attending SPPRA 2008.
