Overview

Wai Kei (Vincent) Ao graduated from the National Taiwan University (NTU) with MSc and undergraduate qualifications in Civil and Structural Engineering and Civil Engineering. Following an invitation from Prof Kuo-Chun Chang in his MSc study, he did "analytical and experimental studies on seismic behaviour of structures with building using passive mass dampers" with Prof Kuo-Chun Chang.

After the MSc course, he went back to his home town Macau to work at BAHH Engineering Consultants Ltd, Macau. He worked there for one and a half year. In that time, he did some works including foundation design, structural design, coordinating engineering plans, program design narrative, etc.

He joined the Vibration Engineering Section (VES) at the University of Exeter (UoE) in 2013 and studied for a PhD under the supervision of Prof Paul Reynolds and graduated in 2017 with the research topic on “electromagnetic damping for control of vibration in civil structures”. 

After the PhD process, he worked at UoE as a graduate research assistant. In 2018, he was awarded a research fellowship related to advanced sensors and modelling for next-generation bridge management in Queen’s University Belfast (QUB) and worked with Dr David Hester. In 2019, he awarded a new research fellowship from Prof Aleksandar Pavic at University of Exeter until present. The key aim of UoE job is corresponding to two project grants: ResIn and DynaTTB. These works are focusing on the dynamic behaviour of offshore structures and the dynamic testing of tall timber buildings around UK and Europe.
