Technical Postgraduate Symposium (TECHPOS) was established in the year of 2002 and was a symposium specially designed for postgraduates in the technical field. The initial objective was to promote the research and development activities among the engineering postgraduate students at the University of Malaya. The successful inaugural TECHPOS then led to the following TECHPOS 2003, TECHPOS 2004 and TECHPOS 2006. To foster international interactions and collaborations, this TECHPOS 2009 aims to bring together researchers especially engineering postgraduate students from all around the world to discuss the advancement in engineering research.
