Biography

Professor Noel O'Dowd is Chair of Mechanical Engineering at the University of Limerick. Noel received his degree in Mechanical Engineering from NUI Galway and went onto compete a PhD in Solid Mechanics from Brown University, USA. After completing his PhD, he took up a research fellowship with the Graduate Aeronautical Laboratories at the California Institute of Technology. Professor O'Dowd then joined the academic staff at Imperial College London for thirteen years before joining the University of Limerick in 2006. He was Vice-Chair of the American Society of Pressure Vessels committee on Materials and Fabrication for four years and is a Visiting Professor at Imperial College London. Professor O'Dowd's research is in the area of computational mechanics and fracture mechanics of engineering materials. He has published over a hundred and thirty research articles in these and related areas.
