Prof. Liam O'Mahony is a Principal Investigator in the SFI Research Centre APC Microbiome Ireland and a Professor of Immunology at University College Cork’s Dept of Medicine and School of Microbiology. He is leading a team whose early research findings suggest that an ongoing immune response may be one reason why some patients develop long-term post-COVID symptoms.
Prof. Liam O’Mahony received his BSc in Microbiology from University College Cork, Ireland in 1994 and his PhD in Immunology was awarded in 1998 by Trinity College Dublin, Ireland. Thereafter, Dr. O’Mahony performed post-doctoral research at the Department of Microbiology, University College Cork, Department of Medicine, University College Cork, and the Digestive Diseases Division, UCLA. Dr. O’Mahony was a Principal Investigator at the Alimentary Pharmabiotic Centre, University College Cork, from 2003 to 2008. From 2009 to 2018, he was head of Molecular Immunology at the Swiss Institute of Allergy and Asthma Research, University of Zürich, Switzerland. He is currently the Prof. of Immunology at the Departments of Medicine and Microbiology, APC Microbiome Ireland, National University of Ireland, Cork, Ireland. He is also currently an EAACI executive committee member and is an Allergy associate editor. His research interests are focused on the molecular basis for microbe and metabolite modulation of mucosal inflammatory responses. In particular, Prof. O’Mahony is investigating the basic mechanisms by which microbes influence allergic sensitization within the gut, skin, and lungs.
