Biography

Dr. Helen Wu is a senior lecturer at the School of Computing, Engineering and Mathematics at the University of Western Sydney, Australia. Helen was awarded a Bachelor Degree in Mechanical Engineering at Sichuan University in China and a PhD in Civil Engineering at the University of Technology, Sydney. She has twenty years experience in teaching, research and consulting relating to the dynamic response of materials, machines and structures including vibration and condition monitoring.

Before joining UWS, Helen worked at UTS, ECU and Hyder Consulting, a multi-national consultancy, where she has been involved in conceptual, detailed design and implementation of tests on many projects related to vibration and noise control. She has expertise in conducting full scale measurements and analyses of civil engineering structures such as bridges, railway tracks, tunnels, and buildings.

An interesting project in which Helen was a project manager was to conduct full scale vibration measurements of ‘BurjKhalifa Dubai’ (the tallest building in the world) during various stages of the construction. She participated in the design of a vibration monitoring system to monitor the building movement induced by wind and possible future earthquake attacks. Helen was also involved in the project of Epping to Chatswood Rail Link (ECRL) during design and construction stages.
