Xu Chi (Dr)
Scientist I
Planning and Operations Management
Introduction:Dr Xu Chi worked as a project engineer in Nanyang technological University on the project of localization and identification for ultra wideband (UWB) enabled sentient computing which is funded by SERC A-STAR from year 2006. In the project, he designed the time-of-arrival (TOA) and positioning estimation algorithms for UWB sensor network. Currently, he is a research scientist of Singapore Institute of Manufacturing Technology (SIMTech) and focuses on development of technologies for track and trace information management and synchronization.
Research Interest:Track and trace information management and synchronization, complex event processing
