Barry graduated from University of Limerick in 1987 with a B.Eng in Materials Engineering and then worked as a project engineer at BHP Laboratories in Limerick until 1995. During this time he worked on materials research projects investigating aerospace alloys, engineering ceramics and medical device materials. He also completed an M.Eng in 1991 on lightweight alloys for satellite structures. Barry joined Boston Scientific in 1996, working in R&D on projects to develop materials and processes for a range of self-expanding devices and balloon-expanding stents. Subsequently he was Technical Team Leader on a number of medical device technology projects covering topics such as iridium oxide stent coatings, alternative stent materials and novel drug delivery concepts. Barry returned to university, completing a PhD in 2009, in the field of MRI-compatible implant materials. He has since worked as Principal Investigator and Project Manager on a number of medical device projects relating to biodegradable magnesium implants and peripheral vascular stents. Currently he is NUI Galway's project manager on an FP7 project that is developing a tissue-engineered tracheobronchial stent.
