Executive Team




John Hogan, Chief Commercial Officer

John is Chief Commercial Officer (CCO) of Glantreo and has been instrumental in transforming Glantreo from an academic venture to a commercial and market focused company. Prior to joining Glantreo he held various Business Development & Financial Leadership roles within KineMatik (an Irish based enterprise software company) and he has also served as Commercial Director of Evergreen Foods. He held various positions including working for the Irish Department of Foreign Affairs in Ireland, Brussels and Vienna. John is a Chartered Accountant and received a Bachelor of Commerce degree from UCC. His loves are sports (rugby, golf, hurling) and family (wife Rachel and four kids). His goals for this year are to introduce 2 new technology lines in Glantreo and play off a single figure handicap in golf. Admittedly, these may be mutually exclusive.

John Hanrahan, Chief Technical Officer

John has been Chief Technical Officer (CTO) of Glantreo since 2008. John is one of the co-founders of Glantreo. He has seen it successfully transition from an academic based company to a successful commercial entity. John completed his PhD in materials science at UCC (Cork) in 2003. John held several post doctoral positions prior to co-founding Glantreo. The most successful parts of his scientific research have been licensed to Glantreo. John has authored in excess of 20 peer reviewed publications with several patents also filed. It gives John great pleasure to see jobs and wealth being created off the back of solid scientific research. When not in the laboratory John likes to play football/soccer (for our US cousins!) with his local club. Of course family life (wife + 3 ‘smallies’) also takes up a significant portion of his free time!

Joseph Mc Grath, Senior Operations and Development Chemist

Joseph McGrath join Glantreo in 2018. Joe is an experienced and innovative PhD Materials Chemist, with strong team working and leadership skills developed in roles in industry and academia. He graduated from Tyndall National institute in 2013 with a PhD entitled ‘Development of large scale colloidal crystallisation methods for the production of photonic crystals. Joe is skilled in materials analysis (SEM, viscosity, pH, mechanical, optical, and thermal analysis), and is experienced in chemical handling and testing (particulates, adhesives, polymers). Joe has gained expertise in Quality systems and standards, and Good Manufacturing Practice (GMP) during his time in industry. Joe has several years’ experience in supervising, mentoring, and training junior staff members and PhD students. He is an avid fan of lifelong learning continuing to adapt and grow his knowledge to meet changing markets. Joe thoroughly enjoys sharing his knowledge with children to foster a love of science and has volunteered as a STEAM demonstrator at various science events. Joe is also a keen football fan and has coached his son’s team for the last 6 years.

Scientific Advisors


Professor Michael A Morris

Mick graduated with a PhD from Liverpool University in 1982. He was a post-doctoral fellow at Imperial College in London before moving to Strathclyde University as a lecturer before, in 1987, taking an ICI endowed lectureship at Cardiff University for research into surface science and catalysis. This was followed by a move to ICI as a research scientist with particular interest in developing high temperature catalysts and during this period he worked with academic groups in Cambridge, Nottingham, UMIST and Edinburgh. He was appointed to a post in Materials Chemistry at UCC in 1993 where he currently leads the materials science group and is currently Head of Department. Prof Morris is also a Principal Investigator at the Tyndall National Institute. Prof Morris is also associated with the new AMBER research centre at TCD where he is responsible for handing industrial engagement. Prof. Morris has authored over 300 peer reviewed papers and more than 20 patents and has an H-index of 38. He has some strong industry relationships with close industrial links with several companies including Intel, Merck Millipore and Depuy that have supported his work in several industrial fields.
