Professor Padraic Fallon

Professor of Translational Immunology (Clinical Medicine)

Interim IMM Director (Molecular Medicine Ireland)

Professor Padraic Fallon heads the Translational Immunology Group. Prof Fallon is Professor of Translational Immunology in the School of Medicine, TCD. Previously, Fallon was a Wellcome Trust Fellow in the University of Cambridge, UK, investigating immune modulation by schistosomes. Since returning to Ireland in 2001, he has continued his research, elucidating underlying mechanisms of aberrant immune function and novel therapeutic strategies for inflammatory diseases. The main diseases addressed are allergic lung inflammation (asthma), skin inflammation (eczema), inflammatory bowel disease (ulcerative colitis and Crohn's disease).,as well as haemophilia . Since 2007, Prof Fallon has generated over €13 million of funding as Principal Investigator supporting research programmes on inflammatory diseases, clinical immunology and infections (helminths and COVID-19). The main diseases addressed are fibrotic disorders, allergic lung and skin inflammation, inflammatory bowel disease and haemophilia. The research on inflammatory diseases is across the human lifespan; from studies on skin diseases in infants, asthma in adults to the metabolic syndrome in the elderly. Prof Fallon has delivered a number of seminal discoveries across the field of immunology. He is an author of ~220 papers peer-reviwed publications in the leading scientifc journals. Fallon and Luke O"Neill, also Trinity College, are the only scientists in Ireland that have been ranked in top 1% of scientists in the world by citations for publications from 2018-2022 in immunology (Clarivate Analytics).

My research involves two overlapping translational immunology themes. i. The use of mouse models to study pathogen modulation of human inflammatory diseases. ii. Immune phenotyping of patients, in particular children, with inflammatory diseases such as atopic dermatitis and pulmonary fibrosis. Research aims to elucidate new mechanism of modulation of immunity that can alter inflammation and have therapeutic potential. Collaborative activity involves the phenotyping of new transgenic mice. The main diseases addressed are allergic lung and skin inflammation and inflammatory bowel disease. A growing emphasis is applying extensive expertise in animal models of human inflammatory diseases and general pathophysiology of inflammation to functional analysis of new therapeutic molecules/strategies with clinical collaborators and Pharma.
