Profile

Elizabeth Cross is a lecturer in the Dynamics Research Group in the Department of Mechanical Engineering. She was awarded a first class degree in mathematics from the University of Sheffield in 2007 and an MSc (Res) in Advanced Mechanical Engineering, also from the University of Sheffield, in 2008. In 2012 she completed her PhD on Structural Health Monitoring whilst also working as a research associate in her final year in collaboration with Messier-Bugatti-Dowty.

Her specific areas of interest include the development of robust indicators for structural performance and condition and the importation of sophisticated mathematical techniques for use in the discipline of structural dynamics.

Research Interests

Elizabeth’s main research interests are in the field of Structural Health Monitoring (SHM), specifically vibration based SHM, which uses monitored dynamic properties of a structure for condition assessment and damage detection. SHM is still a relatively young field and so much of the research that goes on is confined to the laboratory. While it is true that research into SHM is becoming increasingly popular, it has failed, so far, to be taken up in any major way by industry, despite the obvious economic and safety benefits it could offer.

Elizabeth’s current research is broadly concerned with how SHM can be made to work for the real world and encompasses the application of statistics and machine learning technology, as well as mathematics from other disciplines such as econometrics.
