I received my B.Sc. in Physiology from University College Cork (1974) followed by an M.Sc. in Medicinal Chemistry from Loughborough University of Technology, Leicestershire, UK (1976) and a Ph.D. in Physiology from the National University of Ireland Galway (1985).

I worked as a Biochemist (Basic Grade) in the Institute of Clinical Pharmacology, St. James’s Hospital, Dublin, for 12 months during the period 1974-75. From 1982-85, I was employed as a Biochemist (Senior Grade) at St. John’s & Barrington’s Hospitals in Limerick. This was followed by 27 years as a faculty member at Athlone Institute of Technology (AIT), with an appointment as a Lecturer in the Biomedical Sciences, and then moved to the Royal College of Surgeons in Ireland – Medical University of Bahrain as Senior Lecturer in Physiology in 2013.

Selected honours include highest score in M.Sc. thesis and recipient of a Research Fellowship from the National University of Ireland Galway (NUIG).
