Siobhain O' Mahony


Dr. Siobhain M. O’ Mahony, Department of Anatomy and Neuroscience, APC Microbiome Ireland, University College Cork

Siobhain O' Mahony, Senior Lecturer, graduated with a B.Sc. (Hons) in Neuroscience from University College cork. She then went on to complete a Masters in Neuropharmacology in the National University of Ireland, Galway. As part of her Masters Siobhain worked in the Department of Psychiatry and Neuropsychology in the University of Maastricht, the Netherlands, which was funded by a Marie Curie Fellowship. Siobhain obtained a Ph.D. from the Department of Psychiatry, UCC. She continued her research on adverse early life events and the development of pain-related disorders during a post-doctoral post in the APC Microbiome Ireland, Biosciences Institute, UCC. She then took up a post-doctoral position with GlaxoSmithKline. In 2008 Siobhain was appointed as Lecturer in the Department of Anatomy and Neuroscience at UCC.

Siobhain's main research areas focuses on women’s health investigating the role of the microbiome in endometriosis, menopause and during pregnancy.  She also works on investigating outcomes of adverse events during early life in particular the disruption of the developing gut microbiota and how this can lead to the miscommunication within the brain-gut-microbiota axis. The outcomes assessed include the neurodevelopment of children, stress-related disorders and visceral pain in adulthood and how these may be ameliorated through manipulation of the gut microbiota. Her research group is based in the APC Microbiome Ireland and the department of Anatomy and Neuroscience in the Biosciences Institute and the Western Gateway Building, UCC. She has a H-index of 45 and has many successful national and international academic and industry collaborations.
