Biography


Dr. Ted Vaughan graduated with a First Class Honours Degree in Mechanical Engineering from the University of Limerick in 2007. He was awarded a PhD in Mechanical Engineering in 2011, also from the University of Limerick, for research in the area of computational micromechanics of composite materials, funded through a scholarship from the Irish Research Council for Science Engineering and Technology (IRCSET). Between 2011-2015, he held a position as a postdoctoral researcher in the Centre for Biomechanics Research (BMEC) here at NUI, Galway. During this time, he also held a position as a Visiting Postdoctoral Scholar at the University of Notre Dame, funded through a Postdoctoral Mobility Grant awarded by the Royal Irish Academy. Dr. Vaughan’s research focusses on the development of multiscale modelling techniques to address problems in areas such as composite materials, bone biomechanics and bone mechanobiology. To date, he has published 21 peer-reviewed journal articles in internationally respected journals in all of these fields. In September 2015, he was appointed as a Lecturer in Biomedical Engineering at NUI, Galway.

Research Interests

Dr. Ted Vaughan's current research is focused on the development of multiscale computational models that facilitate a better understand of different aspects of bone biomechanics and mechanobiology. His research has also developed multiscale finite element damage models for composite materials. Some of his research interests include,

  • Multiscale finite element modeling to understand the hierarchical structure of bone tissue
  • Multiscale finite element models to predict mechanical stimulation of bone cells in their native environment
  • Fluid-structure interaction modelling of bone cells and their mechanosensors under in vitro and in vivo fluid flow stimulation
  • Continuum damage modelling and failure prediction of composite materials 
  • Micromechanical modelling of damage and failure in fibre reinforced composite materials
  • Nanoindentation of fibre reinforced composite materials
