Dr. Ted Vaughan is a Lecturer in Biomedical Engineering. His research focusses on development of multiscale modelling techniques to address problems in biomechanics, mechanobiology, medical device design and composite materials. He 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. 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. To date, Dr. Vaughan has published approximately thirty peer-reviewed journal articles in internationally-respected journals in the fields of multiscale modelling, computational biomechanics and medical device design. One of these articles is listed as one of the Top-10 most cited articles published in Composites Science and Technology over the past five-years (currently the leading journal in the field of composite materials). He actively collaborates with a range of Industry partners, including Proxy Biomedical, Meotec Gmbh, Boston Scientific and Stryker.

Multiscale Computational Modelling in Biomechanics and Medical Device Design

Dr. Ted Vaughan has developed a range of multiscale and multiphysics computational modelling techniques to better understand the mechanical behaviour of biological tissues, polymer- and metal-based bioresorbable materials and medical devices. He has developed several finite element-based models to characterise fundamental aspects of bone biomechanics, in particular how composition and architecture of the tissue at the nanostructural-level (e.g. mineral and collagen fraction/arrangement) contribute to mechanical properties at higher length-scales (Figure A). Dr. Vaughan has also developed a range of computational models to inform the design of orthopaedic implants and devices, with particular interest in characterising device interaction with the native tissue during surgical cutting, drilling and fixation procedures (Figure B). He is also using multiscale approaches to optimise the design of textile-based stent-graft systems for peripheral applications.
